3. Chenopodium berlandieri Moquin-Tandon (1840: 23). Lectotype (designated here):― Circa Mexico, Sep. 1828, Berlandier 1906 (G00176930 [image!], image available at http://www.ville-ge.ch/ musinfo/bd/cjb/chg/adetail.php?id=178855&base=img&lang=en); isolectotypes: P00606417 [image!], image available at http:// coldb.mnhn.fr/catalognumber/mnhn/p/p00606417, P00606418 [image!], image available at http://coldb.mnhn.fr/catalognumber/ mnhn/p/p00606418, G00206050 [image!] image available at https://plants.jstor.org/stable/10.5555/al.ap.specimen.g00206050, GH00037169 [image!] image available at https://kiki.huh.harvard.edu/databases/specimen_search.php?mode=details&id=12807, NY324308 [image!] image available at https://sweetgum.nybg.org/science/vh/specimen-details/?irn=290056) Note on the type of Chenopodium berlandieri :―There are at least six duplicates of this collection deposited in four different herbaria, i.e. at P, G, GH, and NY-.All this material correspond to syntypes (Art. 9.6 of ICN). In fact, Moquin-Tandon (1840: 23) reported “v.s. [vidi sicco] in herb. Moricand” and Moricand’s herbarium is currently deposited at G, with duplicate elsewhere (see HUH-Index of Botanists 2023). The specimen G00176930 is here designated as lectotype since it is in better condition and shows flowers and fruits (which features are important in the identification of Chenopodium taxa). There is another specimen of C. berlandieri collected by Berlandier with the number 1906 deposited in G (barcode G00206050), probably a fragment from G00176930 or other duplicate. P, GH, and NY specimens are isolectotypes. Note that in the protologue it is reported “circa Mexico ”, but on the sintypes the locality of collection is Bejar, probably Béjar (now Bexar) Texas, not far from the Mexican border., Published as part of Sandoval-Ortega, Manuel Higinio & Zumaya-Mendoza, Silvia, 2023, Types of some Mexican names in Amaranthaceae s. l.

1. Iresine ajuscana Suessenguth & Beyerle (in Suessenguth 1935: 10) ≡ Iresine ajuscana f. longiflora Suessenguth & Beyerle (in Suessenguth 1935: 10). Lectotype [designated by Borsch et al. (2018: 963–964) as “ holotype ”, here corrected to lectotype (Art. 9.19 of ICN)]: ― MEXICO, Thal von Ajusco, 1870, Hahn 35 (B 100177104 [image!] Image available at http://herbarium.bgbm.org/object/ B 100177104). = Iresine ajuscana f. minutiflora Suessenguth & Beyerle (in Suessenguth 1935: 11). Lectotype (designated by Borsch et al. 2018: 964):― MEXICO. Sallo de aqua, December 1905, Purpus 1807 (B100715445 [image!] image available at https://herbarium.bgbm.org/object/B100715445). = Iresine grandis var. glabrata Suessenguth (in Suessenguth & Merxmüller 1952: 108). Lectotype (here designated):― MEXICO. Oaxaca: Ayutla, Cañon Rio Tlahuitoltepec, 19–27 February 1937, Camp 2720 (NY01259979 [image!] image available at https://sweetgum.nybg.org/science/vh/specimen-details/?irn=1489059; isolectotype: NY01259978 [image!] image available at https://sweetgum.nybg.org/science/vh/specimen-details/?irn=1489058). Notes on the type of Iresine ajuscana:― The protologue of I. ajuscana consists of a detailed morphological description; no mention of a type specimen or citation of a locality and/or a collector there is. Just after the morphological description of I. ajuscana, Suessength & Beyerle (in Suessenguth 1935: 11) describes two forms for this species, distinguishable each other by the size of the tepals: I. ajuscana f. longiflora Suessength & Beyerle (in Suessenguth 1935: 11) and I. ajuscana f. minutiflora Suessength & Beyerle (in Suessenguth 1935: 11). For each one of these forms, locality, collectors and collection numbers are reported (“ Mexico, Staat Mexico, Tal von Ajusco, [leg. L. Hahn, no. 35, anno 1870]; Mexico, Staat Mexico, Sallo de aqua, [leg. C.A. Purpus no. 1803 und 1807]; Amecameca, Sacro Monte 2300 m [Leg. H. Fröderström et E. Hultén no. 1207 und 1208 ― Herb. Stockholm]”). Borsch et al. (2018) designated lectotypes for Iresine ajuscana f. longiflora and I. ajuscana f. minutiflora and proposed both names as synonyms (heterotypic) of I. ajuscana s.s. However, they also mentioned that the holotype of I. ajuscana was the same specimen as the one designated as lectotype of I. ajuscana f. longiflora. However, this cannot be possible according to Art. 9.1 of ICN, because no holotype was indicated in the protologue and the material cited are syntypes (Art. 9.6. if ICN). According to the Art. 9.10 of ICN, Borsh et al.’s indication as holotype (barcode B100177104) is treated as an error to be here corrected as lectotype. I. ajuscana and I. ajuscana f. longiflora are homotypic synonyms. Note on the type of Iresine grandis var. glabrata: ―The protologue of I. grandis var. glabrata consists of a short description; a locality (Gebiet von Ayutla, Hoch-paβ zwischen Ayutla und Tumazulapa, canon des Rio Tlahuitoltepec.- Exp. New York Bot. Garden 1937), a collector (W.H. Camp), a collection number (2720), and the herbaria where the material was deposited (“Herb. Bot. Garden New York ”, referred to the Herbarium NY) are given. We traced two specimens at NY, one of which was reported by Borsch et al. (2018) as the holotype of I. grandis var. glabrata (the other specimen indicated as isotype). According to Art. 9.6 of ICN, these two specimens (barcodes NY01259978 and NY01259979) are syntypes, and a lectotypification is necessary. NY01259979 is here designated as lectotype, since it is a more complete specimen, matches with the protologue, and the current concept in Iresine (Calderón de Rzedowski 2005). NY01259978 is the isolectotype. Notes on the identity of Iresine rubella Suessength (in Suessength & Merxmüller 1952: 109):― Suessenguth & Merxmüller (1952: 109) mentioned in the protologue that the type material of Iresine rubella is deposited at BM (“Herb.Brit.Mus.”). However, after a digital search, no original material was found by us in this or other herbaria. Further, after contacting the BM staff, we verified that no material of I. rubella collected before 1890 is currently deposited at the Herbarium (we also asked for specimen identified as I. ajuscana). So, we reached to the conclusion that the specimen is probably lost. Iresine rubella has been considered a synonym of I. ajuscana by Borsh et al. (2018), and so reported also in TROPICOS (2023) and POWO (2023). However, since the type is lost, the only information available to identify I. rubella is the collection locality (Mexico-Valle, Monte de la Parada) and the morphological description provided in the protologue, where it is mentioned that this species has glabrous pseudostaminodia, bisexual flowers and reddish tepals (Suessength & Merxmüller 1952: 109). I. ajuscana has unisexual flowers and pubescent pseudostaminodia, feature not described in the protologue (Suessenguth 1935: 10) but that can be observed in the type material (B100177104, S05-5664), so it is unlikely that I. rubella is a synonym of I. ajuscana. The species of Iresine reported to the Valley of Mexico are I. ajuscana, I. schaffneri Watson (1886: 437), I. cassiniformis Schauer (in Nees ab Esenbeck & Schauer 1847: 709), I. latifolia (Martens & Galeotti 1843: 349) Bentham & Hooker (1880: 42), and I. interrupta Bentham (1844: 156) (see Calderón de Rzedowski 2005), but no one of these taxa matches with the morphological description in the protologue of I. rubella. Since the identity of I. rubella could not be confirmed, this name was not here considered as synonym of I. ajuscana. Syntypes of Iresine ajuscana:― MEXICO, Sallo de aqua, December 1905, Purpus 1803 (B100715444 [image!] image available at https://herbarium.bgbm.org/object/B100715444); Amecameca, Sacro Monte, 3 March 1932, Fröderström & Hultén 1207 (S05-5665 [image!] image available at https://herbarium.nrm.se/specimens/S05-5665); Amecameca, Sacro Monte, 3 March 1932, Fröderström & Hultén 1208 [image!] image available at https://herbarium. nrm.se/specimens/S05-5664).

2. Iresine interrupta Bentham (1844: 156). Lectotype (designated here):― MEXICO. Tepic, Sinclair s.n. (K000195155 [image!] image available at http://apps.kew.org/herbcat/ getImage.do?imageBarcode=K000195155http://specimens.kew.org/herbarium/K000195155). = Iresine acuminata Moquin-Tandon (1849: 345). Holotype: ― MEXICO. Bates s.n. (P00438664 [image!] image available at http://coldb.mnhn.fr/catalognumber/mnhn/p/p00438664). Note on the type of Iresine interrupta: ― Bentham (1844: 156) provided a short morphological description for Iresine interrupta; no collector name or collection number are given, whereas two Mexican localities (“Tepic”, in the state of Nayarit; and “Acapulco” in the state of Guerrero) are reported. At K there are three specimens of I. interrupta, all bearing a label written by Bentham (barcodes K000195154, K000195155 and K000195156). The label on K000195155 reads “Tepic” and the name “Hooker” and the year 1845, one year after the publication of I. interrupta. However, this information does not correspond to the collector and year of collection since W. Hooker did not collected material from Acapulco and was not part of the H.M.S. (Her Majesty’s ship) Sulphur crew. The collector seems to be Sinclair, whose name is written on the label, just after “Tepic”. Raven (1964) explains why some Bentham’s labels have a date that does not correspond to the collection date, indicating that Bentham wrote the year in which he included the duplicates provided by Hooker in his own herbarium. The label on K000195156 reads “Acapulco” and the last name “Barclay”, who was the official collector sent out by the Royal Botanic Gardens Kew. Some of the material collected by Barclay came into the possession of Hooker, who became director of the Royal Botanic Gardens Kew in 1941, and who provided those specimens to Bentham (Raven 1964). Finally, on the sheet K000195154 reads “ Mexico ” and “Beechey”. W. Hooker sent to Bentham all the specimens collected by Hinds, Sinclair and Barclay and other members of the H.M.S. Sulphur crew. About this matter, Raven (1964) wrote: “It is important to note that all of this material was available to Bentham throughout the time he was conducting his studies, and hence all of it is equally important for purposes of typification”. Borsch et al. (2018) cited one of these specimens (K000195155) as the holotype. According to Art. 9.1 of ICN, that specimen cannot be the holotype, but it is a sintype (Art. 9.6 of ICN). K000195155 is designated as lectotype, matching the protologue and the current concept in Iresine (Calderón de Rzedowski 2005, Sandoval-Ortega 2020)., Published as part of Sandoval-Ortega, Manuel Higinio & Zumaya-Mendoza, Silvia, 2023, Types of some Mexican names in Amaranthaceae s. l.

The family Amaranthaceae has a cosmopolitan distribution and it is one of the most diverse families within the order Caryophyllales. Species of Amaranthaceae live mainly in arid environments, saline habitats, or disturbed areas. Nomenclature is the necessary first-step to study the members of this group, aiming to clarify their identity which is often critical. The types of four names in Amaranthaceae (sensu lato, including Chenopodiaceae)—Chenopodium berlandieri, Celosia monosperma, Iresine grandis var. glabrata, Iresine interrupta—with Mexican loci classici are designated in the present paper, including comments on their identities.

Stilbanthus scandens Hooker filius (1879: 67). Lectotype (designated here):— INDIA. “Hab. Sikkim. Regio subtrop. Alt. 4−6000 ped”, Hooker s.n. (CAL0000217508!) (Fig. 1). Description (Fig. 2):— Large gigantic woody climber with pendulous branches; stems quadrangular, grooved, sparsely pubescent, dense at swollen nodes. Leaves opposite, ovate-elliptic, 5.3–11.8 × 2.5–5.2 cm, base oblique-cuneate to equally cuneate, margins not prominently crenate or entire, apex acuminate, sparsely pubescent above, less pubescent only on nerves beneath; veins 5–7 pairs, prominent; petioles 0.7–1.5 cm long, sparsely pubescent. Flowers in densely flowered spikes; spikes pendulous, 2.0– 8.5 cm long, in terminal spreading trichotomously branched panicles and axillary, sometimes subtended by small foliaceous bracts; peduncles 2.0– 4.5 cm long, densely pubescent. Perianth segments ovate-lanceolate, 8–9 × 3.5–4.0 mm, accrescent, whitish woolly at apex, scarious, striated, midvein not prominent; perianth bracts 3.0–4.0 × 2.0– 2.5 mm, ovate, hairy at apex, midvein extended to mucronate, scarious; bracteoles 1.8–2.0 × 1.0– 1.5 mm, ovate, scarious. Stamens 5; filaments slender, 5.5–6.0 mm long, hairy up to 1/3 of length, connate at base; anthers oblong, c. 1 mm long, 2-celled; staminodes membranous, long ligulate lacerate irregularly. Ovary elliptic-oblong, 2.0– 2.5 mm long, compressed, densely hairy of penicillate at apex, otherwise smooth; style filiform, 4.5– 4.5 mm long, glabrous; stigma capitate. Fruit oblong, 3.0– 3.2 mm long, indehiscent, with a circular rim at apex, smooth except apical part. Phenology:— Flowering and fruiting times September–December Habitat:— Grows in the valleys of warm broad-leaved subtropical forests, 900–2100m. Distribution:— INDIA: Arunachal Pradesh, Nagaland, Sikkim, West Bengal; BANGLADESH, BHUTAN, CHINA, MYANMAR. Lectotypification of the name:— The monotypic genus Stilbanthus was validly described by Hooker filius (1876: 67) by the publication of the species Stilbanthus scandens from “Forest of the Sikkim Sikkim Himalaya at elevation of 4–6000 ped; Herb. Griffith, J.D.H. [Jospeh Dalton Hooker] Fl. August, September”. These Griffith’s and Hooker’s gatherings represent at least two syntypes according to the Art. 9.6 of Schenzhen Code (hereafter reported as “ICN”; Turland et al. 2018). Moreover, Hooker filius (1876) published an illustration (”PLATE 1286”; image available at https://www.biodiversitylibrary.org/item/ 54432#page/168/mode/1up) which is also an original material for the name (Art. 9.3 of ICN). We traced five syntypes, of which three were collected by Hooker filius [CAL0000217508, L1691279 (image at https://bioportal.naturalis.nl/specimen/ L.1691279/term= Stilbanthus +scandens&from=0), C10005461 (image at https://plants.jstor.org/stable/viewer/10.5555/al.ap. specimen.c10005461?loggedin=true),] and two by Griffith [K000848078 (image at http://apps.kew.org/herbcat/getImage. do?imageBarcode=K000848078) and CAL0000217104). Griffith’s collections (K000848078 and CAL0000217104) include the script (stamped) “HERBARIUM BENTHAMIANUM 1854”, so confirming that Hooker filius seen them. Note that the herbarium and types of Joseph Dalton Hooker (son of William Jackson Hooker) are mainly preserved at K (HUH-Index of Botanists 2013 +), where strangely we did not find any Hooker’s collection (but only a Griffith’s one). We here designate CAL0000217508 as the lectotype of the name Stilbanthus scandens: it matches the protologue, is well preserved, and corresponds to the correct concept of the species (see e.g., Bao et al. 2003, Mao et al. 2017, Paul & Chaudhury 2019). Taxonomic notes:— Hooker filius (1876: Pl. 1286) illustration does not exactly correspond to the original description. The shown staminodes is filiform with plumose apex while those are thin membranous and tored at random heights in to filiform appendages or irregularly lacerate. Apart from this, stamens are also equal to staminodes in studied specimens which is contradictory in figure. The shown ovary is glabrous at apex while it is found bearded or pencillate all around the style base. Hence, authors are discussing first time these errors to avoid confusion on identity, circumscription and illustration mismatch. Other specimens examined:— INDIA.

(G147762/1!, image of the lectotype available at http://www.ville-ge.ch/musinfo/bd/cjb/chg/adetail.php?id=138993&base=img&lang=en). Description:— Herbs 6–20(–25) dm tall, monoecious, annual (therophyte). Stems erect, glabrous (pubescent in the upper part), green to reddish, often branched. Leaves usually green, ovate to ovate-lanceolate, rhomboidal [(2.0–)3.0– 8.0(–13.0) × (1.0–)1.5–6.0(–6.0) cm], with usually entire margins, apex acute or obtuse, mucronate, base cuneate, usually glabrous, petioled [petiole (1.0–)1.5–4.0(–6.0) cm long]. Synflorescences terminal, panicle-like, the main florescence usually up to 15 cm long (longer than the paraclades), usually green. Floral bracts greenish or yellowish, lanceolate to lanceolate-linear [(2.5–4.5(–6.0) × 1.0– 1.5 mm)], 1.6–2.0 times longer than the perianth, acute, awned, with membranous border abruptly interrupted at the half, margin entire, glabrous. Staminate flowers with 5 tepals, ovate-lanceolate; stamens (4–)5. Pistillate flowers with 5 tepals, ovate to lanceolate [(1.5–)2.0–2.5(–3.0) × 0.5–0.7 mm], with acute and sometimes mucronate apex, median vein usually dark-green; stigmas 3. Fruit usually brown, ellipsoidal [1.5–2.5(–3.5) × 1.0– 1.2 mm], as long as or longer than the perianth, smooth to rugose, dehiscent. Seed lenticular (0.9–1.4 mm in diameter), black to dark reddish-brown. Iconography:— Ardenghi & Parolo (2010: 71, figs. 6b, e), Bayón (2015: 283, Figura 10). Phenology:— Flowering time April (Al-Eisawi & Al-Ruzayza 2015). Habitat and elevation:— Human-made habitat, at 250–300 m a.s.l. (Al-Eisawi & Al-Ruzayza 2015). Chromosome number:— 2n = 32, 34. Alien status:— Neophyte species native to tropical areas of North and Central America, it can be considered as naturalized in Saudi Arabia (Chaudhary 1998). Occurrence in Saudi Arabia (Fig. 14):— Al-Baha, Makkah (Al-Eisawi & Al-Ruzayza 2015), Tabuk (Aljieddani et al. 2021), Bisha (Abbas et al. 2020), and Taif (Abdullah et al. 2017). No finding was done during the filed surveys. Further researches are necessary to verify the distribution of Amaranthus hybridus in the country. Taxonomic annotations:— Amaranthus hybridus is a species characterized in having an high phenotypic variability, especially concerning the features of the flowers. Costea et al. (2001) recognized two subspecies [subsp. hybridus and subsp. quitensis (Kunth) Costea & Carretero] on the basis of the shape of the tepals (ovate and acute in subsp. hybridus, obovate to spathulate tepals and obtuse to truncate in subsp. quitensis). However, one of us (DI) believes that the taxon quitensis is more related to A. retroflexus, at least on the basis of shape and length of the tepal (a study is in progress by DI). In other cases, other taxa (e.g., A. cruentus L. or A. hypochondriacus L.) were accepted as subspecies of A. hybridus (see, e.g. Galasso et al. 2018). Anyway, further several forms were described in the past and a taxonomic revision is still lacking. We here accept the recognition of A. hybridus as separate species from the other member of the aggregate, according to Iamonico (2015)., Published as part of Hassan, Walaa A., Al-Shaye, Najla A., Alghamdi, Salma, Korany, Shereen M. & Iamonico, Duilio, 2022, Taxonomic revision of the genus Amaranthus (Amaranthaceae) in Saudi Arabia, pp. 135-157 in Phytotaxa 576 (2) on pages 151-152, DOI: 10.11646/phytotaxa.576.2.1, http://zenodo.org/record/7461280, {"references":["Townsend, C.

No. 1117.15 (LINN!, image of the lectotype available at http://linnean-online.org/11641/). Description:— Herbs 1–7(–8) dm tall, monoecious, annual (therophyte). Stems erect, glabrous, green to brownish, branched. Leaves black-green, ovate, rhomboidal [(2.0–4.5) × (1.5–)2.0–7.0 cm], with entire (rarely undulate) margins, apex obtuse or rounded (rarely slightly emarginate) and sometimens mucronate, base usually cuneate, usually glabrous, petioled [petiole 1.5–5.0 cm long]. Synflorescences terminal, spike- or panicle-like (sometimes axillary glomerules also occur), the main florescence 3–4 cm long, green to brown, usually thin (5–7 mm in diameter). Floral bracts yellowish or greenish, ovate to lanceolate [0.5–1.0 × 0.4–0.7 mm], shorter (up to ⅓) than the perianth, acuminate, margin entire, glabrous. Staminate flowers with 3 tepals, ovate; stamens 3. Pistillate flowers with 3 tepals, ovatelanceolate or obovate-spathulate (1.2–1.5 × 0.3–0.6 mm), with rounded apex (sometimes acute), mucronate or not; stigmas (2–)3. Fruit brownish, subglobose [(1.2–)1.4–1.7(–1.9) × 1.4–1.6(–1.8) mm] as long as or slighly longer (up to ¼) than the perianth, clearly rugose, indehiscent. Seed lenticular (0.8–1.2 mm in diameter), black or brownish-black. Iconography:— Chaudhary (1998: 239, Plate. 129b), Bayón (2015: 371, Figura 64). Phenology:— Flowering time february. Habitat and elevation:— Human-made habitat, 400–600 m a.s.l. Chromosome number:— 2n = 34. Alien status:— Neophyte species native to South America, it can be considered as naturalized in Saudi Arabia (see also Chaudhary 1998). Occurrence in Saudi Arabia (Fig. 3):— Al hudud ash Shamaliyah (Osman & El-Ameid Abedin 2019), Bisha (Abbas et al. 2020), Jizan, and Taif (Abdullah et al. 2017). Taxonomic annotation:— The name Amaranthus gracilis Desf. was cited by Mandaville (2011) as synonym of A. viridis. Desfontaines’ name was widely discussed by Iamonico (2016b) who reached to the conclusion that it is a nomen ambiguum published by Desfontaines (1804) as nomen novum pro Chenopodium caudatum Jacq. The latter Jaquin’s name was proposed as nomen rejectendum by Iamonico et al. (2015).

Amaranthus L., Sp. Pl. 2: 989. 1753. Type (lectotype designated by Green 1929: 188): Amaranthus caudatus L. Description:— Monoecious or dioecious herbs, usually annual (therophytes), sometimes perennial (hemicryptophytes). Stems erect, ascending, or prostrate, glabrous to tomentose (trichomes uniseriate, whitish to yellowish), green, white, brownish or red, usually branched. Leaves alternate, petioled, with blade lanceolate to ovate, elliptic to deltoid to rhombic; base cuneate to obtuse; apex acute, obtuse, or emarginate, sometimens mucronate; margins entire, sometimens undulate; blade glabrous to pubescent (sometimens hairs only along the veins), with trichomes whitish to yellowish, uniseriate. Synflorescences thyrsoid paraclades arranged in terminal and/or axillary spike- or panicle-like structures or only in axillary glomerules (for details see Iamonico 2015). Bracts 1–5, ovate to lanceolate, with membranous borders thinning to apex or abruptly interrupted at the half of the total length, sometimes keeled; apex acute to obtuse. Flowers unisexual, sessile. Staminate flowers with 3–5 free and more or less equal tepals, ovate to lanceolate, usually glabrous; apex usually acute; margin entire; stamens 3–5, anthers tetrasporangiate with 2 lines of dehiscence, filaments free to the base; pseudostaminodia absent. Pistillate flowers with (0–)2–5 usually free tepals, linear to ovate-lanceolate sometimes spathulate, usually glabrous; apex acute to emarginate (sometimes mucronate); margins entire; one pistil, one ovule, 2–5 stigmas. Fruit dry (dehiscent capsule, or indehiscent utricle), globose to ellipsoid, smooth to strongly rugose on the surface, with often persistent styles; seed one, usually lenticular, smooth to reticulate; embryo annular. General note and diagnostic key:— Twelve non-hybrid species (sixteen taxa, by considering the infraspecific taxa) were here recorded in Saudi Arabia, of which two (A. caudatus and A. tricolor L.) are cultivated only in the country. Four taxa (A. graecizans subsp. graecizans, A. graecizans subsp. sylvestris, A. graecizans subsp. thellungianus, and A. sparganicephalus) are authoctonous, whereas the other ones are aliens, mostly neophytes native to the Americas (Table 2). A diagnostic key of the Amaranthus species occurring in Saudi Arabia follows (the characters of the flowers refer to the pistillate ones, since the features of the staminate flowers have a very low taxonomical value in the genus Amaranthus; see e.g., Mosyakin & Robertson 2003, Iamonico 2015). We include also the two cultivated species (A. caudatus and A. tricolor) which could be found in wild in future. Diagnostic keys for infraspecific taxa of A. blitum L. and A. graecizans are reported after the morphological descriptions of them. 1.

No. 1117.26 (LINN!, image of the lectotype available at http://linnean-online.org/11652/). Description:— Herbs 8–15 dm tall, monoecious, annual (therophyte). Stems erect, glabrous (pubescent in the distal part), red to purple, branched. Leaves red, ovate, rhomboidal 5.0–15.0 × 2.0–8.0 cm), with entire margins, apex obtuse or acute, mucronate, base cuneate, often pubescent, petioled (petiole 1.0–12.0 cm long). Synflorescences terminal, spike-like, up to 60–70 cm long, red to purple, pendulous (terminal florescence 30 cm long or more). Floral bracts greenish to reddish, ovate to lanceolate-linear (3.0–4.0 × 0.8–1.5 mm) longer than the perianth, acute, awned, margin entire, glabrous. Staminate flowers with 5 tepals, ovate; stamens 5. Pistillate flowers with 5 tepals, lanceolate-spathulate (1.0–2.5 × 0.3–1.3 mm), with acute (in this case mucronate) or obtuse (sometimes emarginate) apex; stigmas 3. Fruit brownish, globose (1.5–2.5 × 1.4–1.9 mm), as long as or longer than the perianth, smooth to rugose, dehiscent. Seed lenticular (1.0– 1.5 mm in diameter), dark-brown to brownish-black. Iconography:— Beck (1909: Tab. 297, figures 1–2), Bayón (2015: 277, Figura 6). Phenology:— Flowering time december. Habitat and elevation:— Dry and rocky places, human-made habitat, around 1700 m a.s.l. Chromosome number:— 2n = 34, 68. Alien status:— Neophyte species native to South America (Argentina, Equador, Peru, and Bolivia), it can be considered as casual in Saudi Arabia (Makkah). Occurrence in Saudi Arabia (Fig. 11):— According to Chaudhary (1998: 236) this species would be cultivated only in Saudi Arabia (as ornamental plant). Despite no wild plants were found by us during the field survey, we traced one specimen at IND, so confirming that the species occurs in Saudi Arabia.

Description:— Herbs 5–14 dm tall, monoecious, annual (therophyte). Stems erect, ± glabrous (slightly pubescent in the upper part), red or green, often distally branched. Leaves usually green, ovate to ovate-lanceolate, rhomboidal [(3.0–)5.0–12.0(–14.0) × (1.5–)3.0–6.0(–7.0) cm], with entire margins, apex acute or obtuse (sometimes slightly emarginate), mucronate, base cuneate, glabrous or slightly pubescent, petioled (petiole 1.5–10.0 cm long). Synflorescences terminal, panicle-like, the main florescence up to 15 cm long (longer than the paraclades), red or green. Floral bracts green or greenish, lanceolate (2.0–3.5 × 0.8–1.3 mm), 1.0–1.5 longer than the perianth, acute, awned, with membranous border abruptly interrupted at the half, margin entire, glabrous. Staminate flowers with 5 tepals, ovate-lanceolate; stamens (4–)5. Pistillate flowers with 5 tepals, ovate-lanceolate [(1.5–)2.0–2.5(–3.0) × 0.6–1.5 mm], with acute and sometimes mucronate apex, median vein usually yellow-brown; stigmas 3. Fruit brown, ellipsoidal (2.0–2.5 × 1.4–1.6 mm), longer than the perianth, smooth to slightly rugose, dehiscent. Seed lenticular (1.2–1.6 mm in diameter), dark-brown to reddish-brown. Iconography:— Willdenow (1790: Tab. II fig. 4, sub A. paniculatus), Beck (1909: Tab. 296, figures 3–4, sub Euxolus patulus), Bayón (2015: 280, Figura 7). Chromosome number:— 2n = 32, 34. Alien status:— Neophyte species native to Central America, it can be considered as naturalized in Saudi Arabia (Chaudhary 1998). Occurrence in Saudi Arabia:— Chaudhary (1998) indicated this species [sub Amaranthus hybridus subsp. cruenthus (L.) Thell.] in “the southwest of Saudi Arabia”, without further data about the localities in which it occurs. No finding was done during the filed surveys. Further researches are necessary to verify the distribution of A. cruentus in the country. Taxonomic annotations:— Amaranthus cruentus is quite variable from the morphological point of view, especially concerning the surface of the leaf blade (simple green, green with a white band arch-shaped, or green with a central red spot), the structure of the synflorescences (the paraclades can be erect to patent), and the colour of the stem and synflorescence (from green to red or dark-red). Some cultivars (A. cruentus is also used as ornamental plant), especially those with dark-red synflorescences, can be confused with some forms of A. hypochondriacus, but the two species differ each other by the characters of the bracts (see Iamonico 2015)., Published as part of Hassan, Walaa A., Al-Shaye, Najla A., Alghamdi, Salma, Korany, Shereen M. & Iamonico, Duilio, 2022, Taxonomic revision of the genus Amaranthus (Amaranthaceae) in Saudi Arabia, pp. 135-157 in Phytotaxa 576 (2) on pages 152-153, DOI: 10.11646/phytotaxa.576.2.1, http://zenodo.org/record/7461280, {"references":["Townsend, C.

Type (neotype designated by Iamonico 2016c: 104): UNKNOWN ORIGIN. Herbarium Requien, s.d., s.coll. s.n. (P 04021942!, image of the neotype is available at http://mediaphoto.mnhn.fr/media/14494899601942MO7c2qCCiZJWunt). Description:— Herbs 3–10 dm tall, monoecious, annual (therophyte). Stems erect, glabrous, green, branched. Leaves green, ovate, ± rhomboidal (2.0–)3.0–10.0 × (1.5–)2.0–6.0 cm, with entire margins, apex obtuse, mucronate, base cuneate, glabrous, petioled (petiole 0.8–5.5 cm long). Synflorescences terminal, panicle-like, green to yellowhish. Floral bracts greenish-yellowhish, lanceolate (1.2–2.0 mm long) shorter than the perianth, acute, awned, margin entire, glabrous. Staminate flowers with 5 tepals, ovate; stamens 5. Pistillate flowers with 5 tepals, oblong-spathulate (1.5–2.0) × 0.5–1.0 mm), with acute and mucronate apex; stigmas 3. Fruit brownish, ovoid (1.5–2.0 × 1.0– 1.5 mm), shorter than the perianth, smooth to slightly rugose, dehiscent. Seed lenticular (0.8–1.0 mm in diameter), dark-brown to black. Iconography:— Bayón (2015: 280, Figura 8). Phenology:— Flowering time february. Habitat and elevation:— Human-made habitat (coastal plain), 5–15 m a.s.l. Chromosome number:— 2n = 64 (Behera & Patnaik 1982, Baquar & Olusi 1988, Ugborogho & Oyelana 1992, Greizerstein & Poggio 1994). Alien status:— Neophyte species native to South America, it can be considered as casual in Saudi Arabia. Occurrence in Saudi Arabia (Fig. 12):— Our collections (Jizan) represent the first records of Amaranthus dubius in Saudi Arabia. Nomenclatural notes on Amaranthus dubius:— The name Amaranthus dubius was published for the first time by Martius (1814: 197) who did not reported any diagnosis [only the symbols “*” (that means “ significat plantam, de qua anno 1813 non nisi semen adfuit ”), and “†” (that means “ nomen plantae nondum extra omnem dubitationem positum ”) were indicated (see Martius 1814: 3). As a consequence, Martius’ name is a nomen nudum and invalid from the nomenclatural point of view (Art. 38.2 Ex.1 of ICN). Moquin-Tandon (1849: 260), in his treatment of Amaranthaceae in Candolle Prodromus, reported “ A. dubius Mart. Hort. Erlang. 1814, p. 197 ” as synonym of A. tristis L. and, again, this name cannot be considered as valid according to the Art. 36.1b of ICN. Finally, Thellung (1912: 203) validly published the Martius’ name providing a diagnosis partially taken from Moquin-Tandon (1849, “ calyce vix bracteas superante…sepala oblonga, obtusa, mucronulata…Stam 5, interdum 4, raro 3 ”). Thellung (1912: 203) further indicated the provenance (“ Am. trop. … Indes occ. … Afr. trop.... Afr. trop. … mais peut-être seulement à l’etat d’introduction récente ”) and a reference to Seubert’s Amaranthus tristis (Seubert 1864: 237–238). Note, however, that Seubert (1864) described A. tristis in having “bracteis perogonium subaequantibus” which is a character that contrasts the current concept of A. dubius. In fact, this latter species can be easily identified, among the species belonging to the subgen. Amaranthus sensu Mosyakin & Robertson (1996), by the lenght of its bracts which are clearly shorter than the perianth (see also Mosyakin & Robertson 2003). According to the description given by Seubert (1864: 237–238), the species appears to be the real Linnaean A. tristis, a name that is currently considered as heterotypic synonym of A. tricolor (see Iamonico, 2014a: 148–149). The typification of the name Amaranthus dubius has to be addressed in searching Martius’ collection which, according to HUH Index of Botanists (2013 -onwards), is preserved at the herbaria BR and M. No specimen of original material we traced at M. On the other hand, we traced three specimens at BR bearing labels reporting “HERBARIUM MARTII” (collected before 1806, July 20, 1827 and 1864). However, the “HERBARIUM MARTII” is in contrast with Martius’ so-called “private herbarium” which includes all specimens he received from others but not collected by him himself, and that was given to BR after his death (H. Esser pers. comm.). So, just because there is a label head “HERBARIUM MARTII”, it does not mean the specimen was collected by Martius, it just shows that it had been in his possession (H. Esser pers. comm.). As a consequence, we cannot be sure that the three BR specimens found are part of the original material for the name Amaranthus dubius. No further specimen, useful for the lectotypification purpose, were found. So, a neotypification is required according to the Art. 9.8 of ICN and we here confirm the proposal by Townsend (1974: 471–472) who neotypified the name using a specimen included in the Schwaegrichen’s collection at M (barcode M0107382).

A taxonomic revision of the genus Amaranthus (Amaranthaceae) in Saudi Arabia, based on both field surveys and examination of harbarium specimens, is here presented. Collected exsiccata are kept the Herbaria PNUH and RO. An extensive literature was also analysed. Sixtheen non-hybrid taxa (twelve species) are recognized. Data about nomenclature (accepted names, main synonyms, and types), morphology, chromosome number, chorology (for native taxa) or alien status (for exotic taxa), occurrence in Saudi Arabia, ecology (preferential habitat, phenology, elevation), and taxonomic annotations are provided for each taxon. A diagnostic key is proposed. Four taxa (A. graecizans subsp. graecizans, A. graecizans subsp. sylvestris, A. graecizans subsp. thellungianus, and A. sparganicephalus) are native, whereas the other ones are to be considered aliens. A. dubius and A. blitoides var. blitoides are new for the national flora. Furthermore, the name A. sparganicephalus is neotypified on a specimen deposited at E and a nomenclatural change (A. blitum var. nanus comb. nov.) is proposed.

Description:— Herbs 1–5 (rarely up to 10) dm tall, monoecious, annual (therophyte). Stems prostrate-ascending, glabrous, pale green to pale brown, branched. Leaves green or green-yellowhish, ovate, rhomboidal to deltoid, some subcircular [1.5–3.5(–7.5) × (0.7–)1.5–2.5(–5.0) cm], sometimes fleshy, with entire or undulate margins, apex acute or rounded, often mucronate, base cuneate, glabrous, with marginal white vein, petioled (petiole 1.0– 5.5 cm long). Synflorescences arranged in axillary glomerules, reddish or green. Floral bracts, green or greenish, ovate to lanceolate (1.3–3.0 × 0.4–0.7 mm), shorter than the longest perianth segments, acute, margin entire, glabrous. Staminate flowers with 3(–4) tepals, ovate to lanceolate; stamens 3. Pistillate flowers with (4–)5 unequal tepals, lanceolate, elliptic [the greater 1.5–2.5(–3.5) × (0.7–)1.0– 1.2 mm], with acute to acuminate, and mucronate apex; stigmas 3. Fruit brown or reddish, ellipsoidal (2.0–2.2 × 1.0– 1.4 mm), as long as or longer than the tepals, usually smooth, dehiscent. Seed lenticular (1.5–1.7 mm in diameter), black. Taxonomic annotations:— Amaranthus blitum shows a high phenotypic variability (both in vegetative and in generative characters) and several names (at subspecies, variety, and form ranks) were published in the past, especially in the nineteenth century (see e.g., IPNI 2008). As a consequence, misapplication of names and nomenlcatural disorder exsist. We here recognized two varieties which can be distinguished as follows: 1.

Description:— Similar to var. blitoides but smaller, i.e. 2.0– 4.5 cm tall. Phenology:— Flowering time january. Habitat and elevation:— Human-made habitat, around the sea level. Chromosome number:— Not still counted. Alien status:— Native (endemic?) to Saudi Arabia. Occurrence in Saudi Arabia (Fig. 9):— This species was firstly published for Saudi Arabia by Iamonico (2016c: 91–92; see below “TAXONOMIC NOTES”), sub Amaranthus blitum var. nanus Moq. on the basis of an old Schimper’s collection in Makkah (lectotype). No further finding was done during the filed surveys. Taxonomic notes:— Iamonico (2016c: 91) lectotypified the name Amaranthus blitum var. nanus on a specimens preserved at MPU (barcode MPU022388). We found further three specimens at HAL (barcode HAL0140219) and M (barcodes M0241403 and M0241404) which can be considered as the isolectotypes, here published for the first time. Concerrning the identity of Amaranthus blitum var. nanus, Iamonico (2016c: 91–92) proposed to synonymized it with A. blitoides based on characters of flowers. However, no discussion was provided by Iamonico (2016c: 91–92) regarding the generative characters. Based on the examination of the types of A. blitum var. nanus, and the comparison with specimens and living plants examined by one of us (DI) during the last 15 years, Moquin-Tandon’s variety appear to be very small, i.e. 2.0– 4.5 cm tall, whereas A. blitoides s.str. is at least 10–20 cm tall (see also Akeroyd 1993, Bao et al. 2003, Mosyakin & Robertson 2003, Bayón 2015, Iamonico 2015, Atlas of Living Australia 2022). Waiting further studies (floristic and molecular ones could be useful), we think that this taxon should be maintained as separate for the moment, at least at variety rank.

6. Amaranthus sparganicephalus Thell. in Ascherson & Graebner, Syn. Mitteleur. Fl. 5: 312. 1914 Type (neotype, here designated):— OMAN, Dhofar, J. Qara, nr. Aqarnahawat, Acacia hollow, 880 m a.s.l., 19.09.1985, A. G. Miller 7693 (E00687024!, image of the neotype available at https://data.rbge.org.uk/herb/E00687024). Description:— Herbs, 0.7–6 cm tall, monoecious, annual (therophyte). Stems erect, glabrous (pubescent in the upper part), yellowish, simple or branched (branches sometimes decumbent). Leaves green to dark-green, ovate (1.5–5.5 × 0.6–3.0 cm), with entire margins, apex obtuse to retuse, mucronate, base cuneate, glabrous (short hairs on the nerves of the abaxial surface), long petioled (petiole up to 6.0 cm long). Synflorescences arranged in axillary spherical glomerules, ± 1 cm in diameter, brown to dark-brown. Floral bracts ovate (0.3–0.5 × ca. 0.2 cm), about 1/2 times shorter than the perianth, acute to acuminate, mucronate. Staminate flowers with 3 tepals, green, ovate-lanceolate; stamens 3. Pistillate flowers with 3 tepals, green, ovate-lanceolate (1.0–1.3 × ca. 0.3 mm), with obtuse apex, median vein green; stigmas 2. Fruits arranged in stellate heads (divergent capsules), each one brown, as a double cone (2.75–3.25 × ca. 1.5 mm), longer than the perianth, the half base longitudinally sulcate, dehiscent with point of junction of lid and base cristate-crenulate. Seeds lenticular (1.2–1.5 mm in diameter), black. Iconography:— Townsend (1985: 33, Fig. 6). Phenology:— Flowering time from march to april. Habitat and elevation:— Uncultivated land, around 2000 m a.s.l. Chromosome number:— Not still counted. Chorology:— Species native to eastern tropical Africa (Djibouti, Eritrea, Ethiopia, Kenya, Somalia, Sudan, Tanzania), Arabian Peninsula (Saudi Arabia, Yemen, Oman), and Socotra (POWO 2022b and literature therein). Occurrence in Saudi Arabia (Fig. 6): — Riyadh. Typification of the name Amaranthus sprganicephalus:— Amaranthus sparganicephalus was validly published by Thellung (1914: 312, a note) by a short diagnosis (in german) in which the following two characters were highlighted: the shape of the fruiting glomerules (which resembles those of the members belonging to the genus Sparganium L.; the specific epithet “ sparganicephalus ” derives from this feature) and that of each fruit (“polyedrisch abgeflachten” = “polyhedral flattened”); a morphologic comparison with A. angustifolius Lam. (currently A. graecizans subsp. graecizans) and A. macrocarpus Benth. was also given. Finally the provenance (“tropischen Africa... und Arabiens” = tropical Africa and Saudi Arabia) and three specimens (“ Abessinien: Massaua: Hildebrandt n. 716!; ostafrican. Grabenrand, 1904, Merken!... “Chedrasch et Chedolia, Ehrenberg!”) were reported. According to the Art. 9.6 of ICN, these three citations are syntypes, original material for the name A. sparganicephalus (Art. 9.4 of ICN), and useful for the lectotypification purpose (Art. 9.3 of ICN). Verdcourt (1967: 252) listed 16 specimens of Amaranthus sparganicephalus adding “ syntype ” after three of them, i.e. “ARABIA. Chedrasch and Chedolia, Ehrennberg (B)”, “ ERITREA. Massawa, Hildebrandt 716 (B)”, and “ TANZANIA. Grabenland, 1904, Merker (B)”. These three specimens was also cited (as “Types”) by Townsend (1985: 32) in his treatment of Amaranthaceae for the Flora of Tropical East Africa. According to Shenzen Code, neither Verdcourt (1967: 252) nor Townsend (1985: 32) proposed a correct typification, since they just re-listed the syntypes which was originally reported by Thellung (1914: 312) in the protologue. As a consequence, a lectoptypification is necessary. Note moreover that both Verdecourt and Townsend reported after the syntypes the symbol “†” which would indicate that the specimen was are no longer exsisting. R. Vogt (pers. comm.) informed one of us (DI) that no original material for A. sparganicephalus is preserved at B being probably lost/destroyed during the II World War. Lacking material useful for the lectotypification purpose (Arts. 9.3 and 9.4 of ICN), a neotyipfication is required under the Art. 9.8 of ICN. We here propose to designate, as neotype of the name A. sparganicephalus, a well preserved specimen at E (barcode E00687024) collected in Oman in 1985 which matches the Thellung’s description and the current application of the name (see e.g., Townsend 1985: 32).

5. Amaranthus graecizans L., Sp. Pl. 2: 990. 1753 Type (lectotype designated by Fernald 1945: 139):— U.S.A. Habitat in Virginia, Herb. Clayton No. 442 (BM000051563!, image of the lectotype available at https://data.nhm.ac.uk/object/ca635ca9-9252-42a3-9082-60ec097bc2d6/1641427200000). = Amaranthus angustifolius Lam., Encycl. [J. Lamarck & al.] 1: 115. 1783, nom. illeg. Art. 52.21 of the ICN (Turland et al. 2018). 1 Amaranthus angustifolius was described citing among synonyms an earlier legitimate name (A. graecizans L.). Description:— Herbs 1–8 dm tall, monoecious, annual (therophyte). Stems erect or ascending, ± glabrous (sometimes sparsely pubescent in the distal region), pale to black-brown to reddish, usually branched. Leaves usually green, ovaterhomboidal to lanceolate (decreasing in size towards stem apex), with entire margins, apex acute or obtuse, sometimes mucronate, base cuneate, glabrous, petioled [petiole (1.0–)2.0–5.0(–6.0) cm long]. Synflorescences arranged in axillary glomerules, often reddish. Floral bracts brown-yellowish, lanceolate (1.2–2.0 × 0.3–0.6 mm) as long as or shorter than the perianth, acute, margin entire, glabrous. Staminate flowers with 3 tepals, ovate to lanceolate; stamens 3. Pistillate flowers with 3 tepals, ovate-lanceolate [(1.3–)1.5–2.0 × 0.4–0.7 mm], with acute, and often mucronate apex; stigmas 3. Fruit brown, subglobose [(1.5–)2.0–2.5(–2.7) × (1.0–)1.4–1.5(–1.8) mm], longer than the perianth, rugose, dehiscent. Seed lenticular [1.0–1.3(–1.5) mm in diameter], black to dark-brown. Chorology:— Paleotemperate taxon native to Europe, Central-Western Asia, and Northern Africa (Carretero 1990, Akeroyd 1993, Boulos 1999, Ghafoor et al. 1977, Fennane & Tatou 2005, Le Floc’h et al. 2008), it is considered introduced in some European countries, North America, South Africa, and Australia (POWO 2022a and literature therein). Concerning Saudi Arabia, it is native. At subspecific rank two main distribution areas can be distinguished, the first one including Central and southern Europe plus North Africa [subsp. graecizans and subsp. sylvestris (Vill.) Brenan], the second area being the eastern Europe (Russia and adjacent territories) plus Central and southern Asia [subsp. aschersonianus (Thell.) Costea and subsp. thellungianus (Nevski) Gusev] (see Iamonico 2015: 34). Occurrence in Saudi Arabia:— See varieties. Taxonomic annotations:— Amaranthus graecizans is a species morphologically variable, especially regarding the hairiness of stem, the shape of leaves (lanceolate or ovate-rhomboidal), the structure of synflorescence (with or without terminal synflorescence), the apex of bracts and tepals (acute-mucronate or awned), the margin of seed (obtuse or acute), and the dehiscence/indehiscence of fruit. These variability is currently interpreted recognizing four subspecies, i.e. subsp. graecizans, subsp. sylvestris, subsp. aschersonianus, subsp. thellungianus (see e.g., Costea 2003). Based on our field surveys and according to Chaudhary (1998) three subspecies occur in Saudi Arabia. These taxa can be distinguisced as follow: 1. Bracts and tepals awned (awn 0.3–0.7 mm long)................................................................................................ subsp. thellungianus 2. Bracts and tepals mucronate (mucro about 0.1 mm long)..................................................................................................................3 3. Leaf blade lanceolate [2.0–3.0(–4.0) × 0.5–1.0 cm], ratio length/width of the blade 3.0–6.0................................ subsp. graecizans - Leaf blade ovate-rhomboidal [5.0–6.0 × 2.5–3.0(–3.5) cm], ratio length/width of the blade 1.8–2.2....................... subsp. sylvestris, Published as part of Hassan, Walaa A., Al-Shaye, Najla A., Alghamdi, Salma, Korany, Shereen M. & Iamonico, Duilio, 2022, Taxonomic revision of the genus Amaranthus (Amaranthaceae) in Saudi Arabia, pp. 135-157 in Phytotaxa 576 (2) on pages 141-142, DOI: 10.11646/phytotaxa.576.2.1, http://zenodo.org/record/7461280, {"references":["Fernald, M.

Allmania multiflora V.S.A.Kumar, V.Suresh, S.Arya, & Iamonico sp. nov. (Figs. 7–8). Type:— INDIA. Kerala, Palakkad district, way to Kollengode, ± 160 m, 10°35’34.2”N 76°42’48.1”E, 18 May 2019, Suresh & Anil Kumar 2850 (holotype UCBD; isotype CALI!, KFRI!, RO!). Diagnosis (Table 7):— Allmania multiflora differs from A. nodiflora in having shorter tepals (2.2–2.5 mm and ovatelanceolate vs. 3.3–3.6 mm long and linear-lanceolate), wider gynoecium [(0.3–) 0.4–0.5 mm vs. 0.2–0.3(–0.4) mm long], the diameter of the seeds (1.5–1.9 mm vs. 2.9–3.7 mm), shorter bracts (1.0– 1.2 mm vs. 2.0– 2.4 mm long), shorter and pubescent peduncle (1.0– 1.3 cm long, pubescent with pointed hairs vs. 2.0– 2.7 cm long, glabrous or sparsely pubescent), a higher number of flowers per inflorescence [(15–)30–44 vs. 3–10), stigma pinkish or violet, protruding beyond the anthers (vs. green, not protruding), hairiness of the seeds (highly pubescent vs. glabrous), aril with protruding setae (vs. without setae). Description (Figs. 7–9):—Annual herb, erect or ascending with branches arising from the base, up to 60 cm long. Stem red to violet at the base, green in the rest, pubescent. Stipules hard and deciduous. Leaves ovate-elliptic or lanceolate (1.0–2.5 × 0.5–1.5 mm), apex obtuse or acute, base attenuate, pubescent at the margin and adaxial surface, veined (5–7 pairs of lateral arcuate veins), petioled (0.5–1.0 cm long). Inflorescence in cymose heads, leaf opposed, peduncled, peduncle 1.0– 1.3 cm long, pubescent. Flowers (15–)30–44 per inflorescence; bracts ovate-lanceolate to linear-lanceolate, 1.0– 1.2 mm long, pubescent, with membranous border, abruptly interrupted at about the half (bracts awned), eglandular; bracteoles lanceolate to narrowly ovate, 2.9–3.6 × 0.5–0.8 mm, awned, pubescent outside at the distal part, glabrous at margins. Tepals 5 lanceolate 5.7–7.3 × 0.5–0.7 mm. Stamens 5, 0.6–2.0 cm long, glabrous, creamy white; filaments basally connate, forming a rim around the gynoecium. Pollen polypantoporate, 15–18 µm in size, pores 2–3, pollen surface spinulose. Ovary ovoid, 4.3–5.8 × (0.3–) 0.4–0.5 mm, usually white (sometimes greenish), glabrous; style 0.1–0.2 cm long, extending beyond the filaments, glabrous; stigma capitate, pinkish-violet. Fruits utricle, light green to white, 1.4–2.0 × 0.6–0.8 mm. Seeds ovate, 1.5–1.9 × 1.7–2.1 mm in size, brownish-black, with aril at the base having protruding setae, surface densely pubescent. Etymology:— The new species name refers to the characteristic occurrence of many flowers in a single glomerule. Distribution (fig. 10), habitat, and phenology:— Allmania multiflora is known from few locations in SW-India (Kerala State), at 1000–1250 m of elevation. The distribution area of the new species partially overlaps that of A. nodiflora in Palakkad and Thiruvananthapuram districts. It grows in open areas of the granite hillocks with 25–30 scattered individuals per population. Each population spreads over an area of nearly 1–2 m 2. Flowering and fruiting times are May to September. Conservation status:— The plant propagates mainly through seeds (rarely by rooting at stem nodes). The number of individuals is very few and prone to severe grazing and repeated fire. The exploitation of taxon as a vegetable is another threat, especially by local people along with amaranths. Following the IUCN Red List Guidelines and Criteria (IUCN 2019), Allmania multiflora is assessed as Critically Endangered (ER) in the category [B2a,b(iii,v)] since AOO is about 30 m 2, locations are 4, and decline observed in the quality of the habitat (iii).

First molecular and morphometric investigations for the genus Allmania are presented. A new species of Allmania from the granite hillocks of Palakkad district (Kerala state, India), is described as A. multiflora. It differs from A. nodiflora by shape and length of tepals, diameter of the gynoecium, diameter and hairiness of seeds, length of bracts, length and hairiness of peduncles, number of flowers per synflorescence, colour of stigma, and occurrence of setae associated with the aril. Furthermore, sequence analysis of chloroplast genes (rbcL and matK) also support the distinctness of the new taxon. Original illustrations, photographs, and ecological data are also provided, as well as an evaluation of the conservation status.

Celosia patentiloba C.C.Towns. Hooker’s Icones Plantarum 38: 41, t. 3732 (Townsend 1975); Flora of Tropical East Africa: 13 (Townsend 1985). Type TANZANIA • Newala; alt. 670 m [2200 ft]; 9 Apr. 1959; W. Hay 61; holotype: K (2 sheets). Additional collection studied MOZAMBIQUE • Cabo Delgado Prov., Mueda District; 11°31.822ʹ S, 39°26.504ʹ E; alt. 947 m; 10 Sept. 2009; A. Banze 106; K, LMA. Distribution and habitat Restricted to the Rovuma CoE, known from the Maconde Plateau of Southeast Tanzania and the Mueda Plateau of northeast Mozambique. It occurs in partial or full shade in woodland including in degraded or disturbed areas, at ca 670–950 m a.s.l. elevation. Conservation status This species is currently assessed on the IUCN Red List as Critically Endangered – CR B2ab(iii) – and possibly extinct (Howard et al. 2020). Whilst the new record from the Mueda Plateau adds a second location, this species could be considered to be severely fragmented given that the two known subpopulations are over 65 km apart, whilst the dispersal potential of this species is likely to be very limited given that it is a small understorey herb. Recolonisation between these isolated subpopulations is, therefore, unlikely to occur. Further, there is very little intact wild habitats still present on both the Maconde and Mueda Plateaux which are highly degraded, with much conversion to agricultural land. At Mueda Plateau, for example, there has been an estimated loss of dense woodland and dry forest vegetation cover of over 96% (Timberlake et al. 2011). Whilst this species appears tolerant of some disturbance, it is unlikely to persist in farmlands. Furthermore, as noted by Howard et al. (2020), it is possible that the Maconde subpopulation is no longer extant. Therefore, the assessment of CR B2ab(iii) is upheld here. Taxonomic notes Two collections from the Rondo Plateau in southeast Tanzania (G.P. Clarke 35; Q. Luke 12958; both K) are closely allied to this species but have markedly smaller perianth segments. These collections may represent a further species of Rovuma CoE endemic in Celosia or possibly a distinct variant of C. patentiloba. Further material is desirable to fully assess the extent of this variation., Published as part of Darbyshire, Iain, Burrows, John E., Luke, Quentin & Langa, Clayton, 2022, Cladoceras rovumense sp. nov.
