Nine new combinations including two new names in South American species of Heliotropium (Heliotropiaceae) are proposed in this work: H. antioquianum J.I.M.Melo, replacement name; H. brevilobatum (K.Krause) J.I.M.Melo, comb. nov.; H. fuliginosum (Kunth) J.I.M.Melo, comb. nov.; H. gigantifolium (Killip ex J.S.Mill.) J.I.M.Melo, comb. nov.; H. macrostachyum (Rusby) J.I.M.Melo, comb. nov.; H. rollotii (Killip) J.I.M.Melo, comb. nov.; H. romeroi (I.M.Johnst.) J.I.M.Melo, comb. nov.; H. scabridum (Kunth) J.I.M.Melo, comb. nov., and H. stapfianum J.I.M.Melo, replacement name. Furthermore, Heliotropium romeroi is recorded for the first time in Ecuador and lectotypes are provided for Tournefortia brevilobata K.Krause, T. fuliginosa Kunth, T. macrostachya Rusby, and T. scabrida Kunth.

The Sierra de las Nieves National Park, declared by the Spanish Government in July 2021, is part of the Serranía de Ronda (Western Baetic mountains), which is considered one of the main centres of biodiversity and endemicity of the southern Iberian Peninsula (Andalusia, Spain) and the Mediterranean Basin. The park and its surroundings have an important diversity of vascular plants, mainly due to the orographic, climatic and geological diversity of the area, which is divided into three biogeographical sectors: Rondeño sector (limestones, dolomites and clays), Bermejense sector (peridotites and serpentines) and Aljíbico sector (gneisses and micaschists). This contribution presents the first catalogue of the vascular flora of this national park and its surrounding area, with 1,387 taxa distributed in 104 families and 542 genera. An amount of 79 taxa are endemic to Andalusia and 57 are endangered: 4 are Critically Endangered (CR), 17 are Endangered (EN) and 36 are Vulnerable (VU).

During the preparation of the treatment of the family Heliotropiaceae for Argentina, several names were identified as needing typification to stabilize their nomenclature. As a result, lectotypes are designated for six names (Heliophytum anchusifolium (Poir.) DC. var. angustifolium DC., Heliotropium claussenii A. DC. f. robustior Chodat, H. inundatum Sw. f. elliptica Chodat & Hassl., H. margaritense Hassl. ex I. M. Johnst., H. salicoides Cham., and Tournefortia elegans Cham.) and second-step lectotypes for two names (Heliotropium andinum Rusby and H. maximum Chodat & Hassl.). Furthermore, remarks on types of three names (Heliotropium chrysanthum Phil., H. rugosum Phil., and T. paniculata Cham.) are provided.

Euploca riochiquensis J.R.I. Wood & P. Muñoz sp. nov. Fig. 3. Type:— BOLIVIA, Dept. Chuquisaca, Prov. Oropeza, Río Chico Valley between Bellavista and Zurima, scattered plants in steep gullies on sandstone hills covered in sparse xerophytic scrub 18°44.772’S, 65°08.521’W, 1693 m a.s.l., 17 March 2016, J.R.I. Wood 28121 (holotype: USZ!, isotypes: FHO!, HSB!, K!, LPB!). Diagnosis:— Euploca riochiquensis is related to three other Bolivian species placed in Euploca, E. campestris, E. lagoensis and E. procumbens, but the four species are not very similar in facies and are very unlikely to be confused. Euploca riochiquensis is conspicuously woody forming a much-branched subshrub 0.4–1 m in height with linear leaves 5–15 × 2–4 mm and solitary flowers unlike E. campestris and E. procumbens which have several stems from a woody base reaching a maximum of 50 cm in height, oblong-elliptic to obovate leaves, 7–30 × 6–12 mm and flowers aggregated into scorpioid cymes. Although in E. lagoense the flowers are solitary and axillary, this is a slender, usually prostrate, annual herb of drying mud, the stems E. riochiquensis, which reaches 1 m in height and grows on dry rocky hillsides. Phylogenetic studies (Figure 1) suggest E. riochiquensis is most closely related to the Mexican species, E. mexicana and E. karwinskyi. The three species are somewhat similar in their leaf shape but the two Mexican species differ clearly in their scorpioid inflorescences. Subshrub, mostly 0.4–1 m high. Stems several from a woody rootstock, ascending, woody, much branched upwards; when old, brown with flaky bark, glabrous; when immature, brown, strigose; when young densely strigose and appearing whitish. Leaves subsessile, alternate but often clustered, especially below, 5–15 × 2–4 mm, diminishing in size towards the branch tips, narrowly oblong-elliptic, less commonly lanceolate, base narrowly cuneate, apex acute, margin entire, involute, adaxially grey-green, bullate, strigose, abaxially paler, more densely strigose, pustulate, venation of a single vein prominent abaxially; petioles 0–2 mm long, densely white-strigose. Inflorescence of solitary, very shortly pedunculate flowers borne in the leaf axils, mostly towards the apex of juvenile branches, many apparently aborting leaving small dried calyces; peduncles 0–1.5 mm long; pedicels absent; bracteoles linear-subulate, 2–3 mm long; calyx unequally 5-lobed to base, longest lobe 5 mm long, shortest lobe 3.5 mm, lobes linear-lanceolate, strigose on exterior; corolla 5 mm long, white, tubular with spreading lobes; tube 3.5–4 mm long, strigose externally, lobes ca. 1.5 mm long, oblong-ovate, obtuse at apex; stamens inserted near base of tube, anthers subsessile, oblong, ca. 1 mm long, glabrous; ovary yellowish, conical, pubescent, stigma sessile, ca. 3 mm long. Schizocarp rarely formed, subglobose, pubescent, ca. 1.3 mm in diam., tardily splitting into four rounded nutlets. Distribution:— Endemic to the Rio Chico Valley between Chuquichuqui and Imillahuanusca, especially near Zurima, Prov. Oropeza, Dept. Chuquisaca, Bolivia. Fig. 4 Habitat:— Very locally frequent in sparse xerophytic scrub with abundant Senegalia gilliesii (Steud.) Seigler & Ebinger (2006) on steep rocky slopes in the Rio Chico Valley, some 10–15 km above its confluence with the Rio Grande, principally, perhaps exclusively, on sandstone, between about 1600 and 1900 m. The area is not particularly diverse in terms of species numbers but is very interesting in terms of endemism. As well as the new species, Puya ugentiana L.B.Sm. (Smith 1966), Puya valida L.B.Sm. (Smith 1964), Salvia graciliramulosa Epling & Játiva (1966), Tillandsia helmutii L.Hrom. (Hromadnik 1990), Tillandsia oropezana L.Hrom. (Hromadnik 1989) are other pinpoint endemics growing on the same formation in the same area. Other Bolivian endemic species occurring in the same dry valley include Brongniartia ulbrichiana Harms (1908), Hippeastrum mollevillquense (Cárdenas) Van Scheepen (1997: 18), Justicia consanguinea (Lindau) Wassh. & C.Ezcurra (1997), Funastrum rupicola Goyder (2008), Salvia orbignaei Benth. (1848), S. sucrensis J.R.I. Wood (2007), Tecoma beckii A.Gentry ex J.R.I. Wood (2008), Tillandsia lotteae H.Hrom. (Rauh 1978) and Varronia lantanifolia J.S.Miller & J.R.I.Wood, but all of these occur in other locations in the inter-Andean dry valley system of central Andean Bolivia. The Río Grande Valley and its tributaries the Río Chico and Río Grande are remarkable for the presence of scattered, narrowly restricted endemics from many plant families. An earlier publication (Wood 2013) has drawn attention to the endemics found in Puente Santa Rosa area, while this paper highlights one of the side valleys, the Río Chico valley in Chuquisaca as an important centre of endemism. Phenology:— Found in flower towards the end of the summer rainy reason, all collections of flowering material having been made in March. Etymology:— The epithet riochiquensis is derived from the Río Chico, to whose valley the species is endemic. Preliminary conservation status:— As far as it is known, this species is restricted to a limited area of the Rio Chico Valley in Chuquisaca. All collections have been made close to the Sucre-Cochabamba highway and no search has been made at any distance from this road. As the steep scrub-covered slopes on various geological formations including sandstone extend over huge botanically unexplored areas, there is no reason to believe this species is as rare as the few records might suggest. Equally, there are no obvious threats to this habitat from mining, deforestation or human settlement and even goats do not seem to find this species particularly palatable. Until systematic search has been made in suitable areas in the same general region, this species can only be realistically assessed as Data Deficient (DD) according to IUCN (2019) guidelines. Additional specimens examined (Paratypes):— BOLIVIA. Dept. Chuquisaca, Prov. Oropeza, Río Chico Valley ca. 15 km below Chuquichuqui, scattered plants on open, almost bare sandstone hill slopes in hot, dry valley ca. 1900 m, 26 March 1995, J.R.I. Wood 9612 (K, LPB, USZ); ibid., 1 km north of Zurima, hot valley lined with steep-sided red sandstone hills covered in sparse spiny bushland. Locally frequent in rock crevices on steep open sandstone hills, 1800 m, 15 March 2002, J.R.I Wood 17828 (HSB, K, LPB). Morphological charactersation. Euploca riochiquensis is unlikely to be confused with any other species once it is recognised as belonging to Heliotropiaceae. The combination of shrubby habit with small solitary white flowers appears to be unique., Published as part of Wood, John R.

Many new combinations are needed in Euploca, previously regarded as Heliotropium section Orthostachys, to correspond with results of our forthcoming, world-wide, molecular phylogenetic analysis. We also need these names for our many δ13C determinations that identify many Euploca species exhibiting C4 photosynthesis and show that other Euploca species are not C4. Here we make the many new combinations required to support these results.

Subshrubs or shrubs 0.9���1.85 m tall, always erect; stem exfoliating by cinereous longitudinal plates; leaves held horizontally, petiolate, with base obtuse, apex obtuse or acute, velutinous-whitish on both surfaces; venation brochidodromous; inflorescence 9���23 cm long, opposite to the leaves, solitary; flowers 8.4���8.9 mm long, always pedicellate, the calyx 3.7���3.8 mm long, velutinous externally, with lobes triangular or oblong-triangular, the corolla 7.4���7.8 mm long, salverform, entirely yellow. Type:��� BRAZIL. Goi��s: Niquel��ndia, Reserva Particular de Desenvolvimento Sustent��vel Legado Verdes do Cerrado, N��cleo Engenho, ��rea do Coimbra, crescendo sobre solo areno-pedregoso, em topo de morro a 100 m da lateral direita da Caverna Timb��, Cerrado Denso, 14��33���08���S, 48��30���04���W, 644 m a.s.l., 28 January 2021, fl., fr., M. J. Silva 11899 (holotype UFG!; isotypes CEN!, HACAM!, NY!, to be distributed). Subshrubs or shrubs 0.9���1.85 m tall, erect or suberect when greater than 1.5 m tall; adult stems glabrous, cinereous, flaking off in thin longitudinal plates, young stems densely velutinous-canescent or whitish; xylopodium absent. Leaves alternate spiral, held horizontally with Kranz anatomy, petiole 1.8���2 mm long, villous, non decurrent; leaf blades 3���3.8 �� 1.2���1.6 cm, membranaceous, discolored, abaxial surface light green, abaxial surface opaque green or green-whitish, elliptic or ovate-elliptic, apex acute or obtuse, base obtuse, margin flat or slightly revolute, ciliated, velutinous on both surfaces, the trichomes shorter on abaxial surface, whitish; venation brochidodromous, midrib impressed on adaxial surface and prominent on abaxial surface, secondary veins 4���6 pairs, impressed on both surfaces, Inflorescence (9) 10���23 cm long, 1.1���15 cm, terminal, sometimes axillary and opposite to the leaves, always solitary, congested, many flowered; peduncle 1���1.2 cm long, similar to the branches and leaves in relation to the trichomes; bracts 3���3.2 �� 0.8���1 mm, membranaceous, elliptic or oblong-spatulate, persistent, flat, velutinous externally, ciliate, barbelate internally. Flowers 8.4���8.9 mm long; pedicel 1.7���1.8 mm long; calyx 3.7���3.8 �� 0.9���1.1 mm, lobes triangular to oblong-triangular, velutinous externally, glabrous internally; corolla 7.4���7.8 mm long, salverform, always entirely yellow, velutinous externally along its length and in the central portion of the lobes, tube 4���4.1 mm long, lobes 2���2.1 �� 2.5���2.6 mm, widely oval, apex obtuse or rounded, shortly mucronate; stamens subsessile, filaments inserted 2���2.1 mm above the base of the tube; anthers 1.8���2 mm long, cordate, pubescent and slightly coherent at the apex; ovary 0.4���0.5 mm long, style ca. 0.7 mm long, cylindrical; stigma 0.6���0.7 mm long, bifid at the apex. Schizocarp 1.1���1.2 �� 1.8���1.9 mm, globose, shortly pubescent, styles and stigma persistent, nutlets 4, ca. 0.9 mm long, angulate, brownish, with a cavity (pit) in each ventral surface. Distribution and habitat:��� The species has so far been found in the municipality of Niquel��ndia, state of Goi��s (Fig. 3), where it grows on hilltops in open areas of ���cerrado denso��� on sandy-clay and stony soil close to rock outcrops between 644 and 1000 meters of elevation. It draws attention in the landscape for its erect aspect and the slender stems with rhytidome conspicuously flaking off in plates. Among the species of the genus occurring in Brazil, this reaches up to 1.85 m tall, which probably makes its stem topple and be parallel to the ground, when then its inflorescences up to 25 cm in length and in an ascending aspect. Phenology:��� Collected with flowers and fruits between January and March. Etymology:��� The specific epithet ��� decorticans ��� alludes to the species presenting a stem with rhytidome flaking off in grayish longitudinal plates. Preliminary conservation status:��� Euploca decortica ns has an Extent of Occurrence and Area of Occupancy calculate as 179.9 km 2 and 12.000 km 2, respectively so it is considered Endangered [EN B2 ab (iii)]. Despite this, we emphasize that the new species was found in a Permanent Biodiversity protection unit that is the Private Reserve of Sustainable Development Legado Verdes do Cerrado, which ensures its full protection, and that it grows in a very common type of vegetation in the highlands of the state of Goi��s, ���cerrado denso���, so it might be found in other locations in the state of Goi��s, Brazil. Affinities and morphological characterization:��� Euploca decortica ns is morphologically most similar to E. salicoides (Fig. 4) shown especially by the color of the branches, leaves and corolla and, partly by the habit and appearance of growth. However, E. decorticans is a subshrub or shrub with slender stems presenting 0.9���1.85 m tall, always erect (vs. subshrub with 0.2���0.9 m tall, erect, prostrate or decumbent in E. salicoides), has an adult stem flaking off in longitudinal plates (vs. striated with fissures, but never flaking off), young branches velutinous (vs. strigose or villous); leaves petiolate, held horizontally, the leaf blades 3���3.8 �� 1.2���1.6 cm, elliptical or oval-elliptical, velutinous on both surfaces, with base obtuse and margin flat or slightly revolute (vs. sessile or subsessile, ascending, the leaf blade 0.7���5 �� 0.15���1.4 cm, lanceolate, oblong-lanceolate, oval-lanceolate or broadly ovate, hirsute or villous on the adaxial surface and strigose or tomentose on the abaxial surface, with base truncated or cordate, and margin conspicuously revolute), venation brochidodromous (vs. apparently hyphodromous), inflorescences 9���23 cm long, showing the same trichomes as the branches (vs. 1.1���15 cm long, strigose or tomentose); bracts 3���3.2 �� 0.8���1 mm, elliptical or oblong-spatulate, flat (vs. 2���5 �� 0.5���3 mm, lanceolate or oval, revolute); flowers with 8.4���8.9 mm long, the pedicel 1.7���1.8 mm long (vs. flowers 4���5 mm long, sessile or with pedicel up to 1 mm long), calyx 3.7���3.8 mm long, lobes triangular or oblong-triangular (vs. calyx 2���3 mm long, the lobes elliptical or widely elliptical); corolla 7.4���7.8 mm long, entirely yellow, salverform, velutinous externally (vs. corolla 3���5 mm long, tubular, yellow or white, strigose externally); anthers 1.8���2 mm long, cordate (vs. ca. 1 mm long, ovate); style ca. 0.7 mm long (vs. style 1���1.1 mm long), as well as schizocarp with 1.8���1.9 mm diameter (vs. ca. 1.5 mm).

Made available in DSpace on 2022-04-29T08:38:03Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01 Boraginaceae s.l., the single family of Boraginales, are extremely diverse in terms of morphology, and their species are well distributed in South America especially in Brazilian ecosystems. The pollen morphology of 11 Brazilian native species and four genera (Cordia L., Varronia P. Browne, Heliotropium L. and Myriopus Small) of Boraginaceae s.l. was investigated to expand the morphological knowledge of the species, contributing new data on the palynology, taxonomy, and conservation of the family. The pollen grains were acetolyzed, measured, photographed using light microscopy (LM) and scanning electron microscopy (SEM), and described qualitatively. The analyzed species present differences in size, shape, type and number of apertures (3-porate, 3-colpate, 3-colporate and heterocolpate) and exine ornamentation (psilate, echinate, microechinate-verrucate, reticulate and rugulate) of the pollen grains, allowing the species studied to be distinguished. Multivariate analysis of measurements confirms the qualitative description and pollen diversity in Cordiaceae species. Smaller diameter values and similarities in aperture and exine ornamentation characterize the Heliotropiaceae species. Our data reinforce the taxonomic importance of pollen morphology and of Boraginaceae s.l. as eurypalynous.

Five new combinations in Myriopus (Heliotropiaceae) are proposed in this paper: Myriopus andrade-limae, M. isabellinus, M. mapirensis, M. selleanus, and M. subsessilis. Myriopus isabellinus and M. selleanus are restricted to Costa Rica and Haiti, respectively, and other three species are distributed in South America; M. andrade-limae is endemic to Brazil.

The studies were carried out as part of the “Flora of Uzbekistan” project, which represents a transition from the classical stage of the existence of botanical information, available in the form of herbarium collections and paper publications summarizing them, to the modern stage of electronic accumulation, processing and dissemination of information. When conducting a critical revision of the species of the families Heliotropiaceae and Boraginaceae for the next volume of the “Flora of Uzbekistan”, an important stage in the work is the selection of type specimens and typification. The article contains information about 100 type specimens of the names of 38 species of the Heliotropiaceae and Boraginaceae kept in National Herbarium of the Uzbekistan of Institute of Botany of Academy of Sciences of the Republic of Uzbekistan (TASH), 22 specimens kept in Herbarium of the Komarov Botanical Institute (LE), 6 specimens kept in D. P. Syreitcshikov Herbarium of Biological faculty of Moscow State University (MW), and 2 specimens kept in Muséum National d’Histoire Naturelle, Paris, France (P). The type category is indicated, text of the original label and text of the protologue are cited for each specimen. Among 130 specimens found in the collections, there are 25 lectotypes, 29 isolectotypes, 35 syntypes, 12 holotypes, 7 isotypes, 6 paratypes and 17 authentic specimens. The lectotypes of the names of 13 species from genera: Cynoglossum, Lappula, Macrotomia, Nonea, Onosma, Paracaryum, Rindera, Stephanocaryum are designated. The selection of herbarium sample as a lectotype was confirmed for 7 taxa. The collection of type specimens presents the species described by M. G. Popov, K. Z. Zakirov, V. K. Paziy, A. P. Chukavina, E. G. Chernyakovskaya, R. V. Kamelin, A. D. Lee from the territory of all the republics of Central Asia: Kazakhstan, Uzbekistan, Tajikistan, Kyrgyzstan and Turkmenistan. The earliest collections in the type collection belong to G. S. Karelin and I. P. Kirilov.&nbsp, Исследования проведены в рамках проекта «Флора Узбекистана», который представляет собой переход от классического этапа существования ботанической информации, доступной в виде гербарных коллекций и обобщающих их бумажных публикаций, к современному этапу электронного накопления, обработки и распространения информации. При осуществлении критической ревизии видов семейств Heliotropiaceae и Boraginaceae для очередного тома «Флоры Узбекистана» важным этапом работы служит выделение типовых образцов и проведение типификации.

The genera of Heliotropiaceae in Argentina. The generic delimitation within Heliotropiaceae has changed in the past years. However, these changes are not reflected in recent taxonomic publications on the group in Argentina. In this contribution, the taxonomy of the genera of Heliotropiaceae in Argentina is updated and all accepted species are enumerated. Brief generic descriptions and a key to distinguish the genera are provided. The genera of Heliotropiceae accepted in this work are Euploca, Heliotropium, Ixorhea and Myriopus, all of them present in Argentina. Lectotypes for Heliotropium hasslerianum (?Euploca hassleriana) and Heliotropium patagonicum are here selected and the new combination Heliotropium lilloi (based on Tournefortia lilloi) is proposed in order to complete the taxonomic treatment of the family in Argentina.

DOI : http//dx.doi.org/10.15553/c2017v721a8The intensive geographical exploration of the world, starting in the mid eighteenth century, resulted in the discovery of numerous plant species new to science of which many were subsequently introduced into cultivation in Europe. Etienne-Pierre Ventenat (1757–1808) contributed widely to this process. After the end of his curatorial and teaching commitments at Sainte-Genevieve Abbey in Paris he became an active botanist following in the footprints of his mentor Charles Louis L'Heritier de Brutelle (1746–1800). Ventenat was attracted by a trend of his period : publishing magnificent botanical books splendidly illustrated. He published three flower books from 1800 to 1808 on exotic plants recently brought to France from all over the world by various expeditions. Two flower books describe plants cultivated by Jacques-Martin Cels (1740–1806), an influential horticulturist who had built one of the most impressive plant collections of his period at Montrouge, just outside Paris. Another plant lover was Empress Josephine (1763–1814). After her wedding with Napoleon Bonaparte (1769–1821), she bought in 1799 the splendid estate of Malmaison west of Paris. There the Empress assembled a remarkable collection of exotic plants, largely cultivated in her orangery and the “Grande Serre Chaude”. She engaged Ventenat to describe her luxurious collection and the artist Pierre-Joseph Redoute (1761–1841), later known as the “Raphael des fleurs”, to depict the plants. This resulted in the famous flower book Jardin de la Malmaison, a masterpiece of botanical illustration. Ventenat, exhausted, passed away in 1808. His personal herbarium was bought in 1809 by Benjamin Delessert (1773–1847) whose herbarium was later donated to the City of Geneva in 1869. In his three flower books Ventenat treated a total of 343 plant names. A search in the herbaria of Geneva, Paris, Berlin and Madrid resulted in the finding of nearly all the original material relative to these names. A comprehensive list of names is provided here with comments on the origin of the plant material in the context of the explorations of this period, as well as information on typification and currently accepted names. In his three flower books Ventenat validated the names of 208 taxa (207 species and one variety) new to science : of these 67 are still accepted today as published while 52 are basionyms of names currently placed in another genera. Of these 208 names, lectotypification was not needed for 116 and the holotype has been found in G. For the remaining 92 names, 21 previous lectotypifications have been published but 5 of them needed a second-step lectotypification ; 70 new lectotypes have been selected and one neotype. Further comments on the typification of ten species are also provided.

Tournefortia albifolia J. S. Mill. and T. longipedicellata J. S. Mill. are described as new from Costa Rica, bringing the total number of Tournefortia L. species known from Costa Rica to 16. They are described, their affinities are discussed, information is provided to allow them to be separated from the other species with which they may be confused, and their conservation status is determined.

A large number of specimens used as original material for the description of new species were destroyed in the bombing of the Berlin-Dahlem herbarium, B, in 1943. Six lectotypes are designated here for Cordia discolor Cham., Cordia multispicata Cham., Cordia tobagensis Urb. and its variety broadwayi Urb. in the Cordiaceae and for Tournefortia paniculata Cham. and Tournefortia ulei Vaupel in the Heliotropiaceae.

Three new combinations in Myriopus (Heliotropiaceae) endemics from Brazil are proposed in this paper: Myriopus gardnerianus, M. membranaceus and M. salicifolius.

Two new combinations in Euploca (Heliotropiaceae) from Marquesas Islands, endemic from French Polynesia, are proposed in this paper: Euploca marchionica and Euploca perlmanii.

Se efectúan cuatro nuevas combinaciones en los géneros Euploca y Myriopus (Heliotropiaceae): Euploca aurata , E. catamarcense , Myriopus breviflorus y M. paniculatus var. austrinus.
