Abstract
Biscutella incana is endemic to the southern Apennine Peninsula (Italy) and was first described by Michele Tenore in 1826 from Calabria. It belongs toB. ser.Levigatae , the most morphologically diversified and critical series within the genus. In order to fix the application of this name, a lectotype housed in NAP was designated here. An updated and detailed morphological description, distribution and information about habitat and phenology are provided. Furthermore, a chromosome count made on a new population discovered in Dolomiti Lucane (Basilicata, southern Italy), confirmed thatB. incana is diploid (2n = 18). [ABSTRACT FROM AUTHOR]- Published

While conducting phylogenetic analyses of sequence-capture data of Australian members of Asteraceae tribe Astereae, we found that Elachanthus pusillus F.Muell., Isoetopsis graminifolia Turcz. and Kippistia suaedifolia F.Muell. formed a clade with Minuria. We, therefore, conducted an analysis focused on this clade, but with replicate samples of the three smaller genera, and confirmed our results. Kippistia had been synonymised under Minuria between 1876 and 1980, when it was reinstated. Elachanthus and Isoetopsis had not previously been suggested to be part of Minuria , and, indeed, Isoetopsis had been considered so morphologically divergent that even its tribal affiliations were long controversial. However, on closer examination, Elachanthus and Isoetopsis are strikingly similar to Minuria , especially in cypsela and pappus morphology. The evolution of both genera from a common ancestor in Minuria appears plausible in the light of their overall similarity to annual species of that genus such as M. annua , their multiple uniform rows of herbaceous phyllaries with scarious margins, a pappus of scales v. the tendency of Minuria to form pappi with scale-like bases, female outer and male inner florets, and a cypsela indumentum shared with some species of Minuria. We propose the following three new combinations under Minuria : M. pusilla , M. glabra and M. graminifolia. We conducted a phylogenetic analysis of Minuria and related genera and found that Elachanthus , Isoetopsis , and Kippistia phylogenetically nested in Minuria. Before 1980, Kippistia had long been considered part of Minuria. Morphological examination showed many similarities between Eleachanthus , Isoetopsis , and annual species of Minuria. We publish new combinations for four species, synonymising the three smaller genera. (Image credit: Alexander Schmidt-Lebuhn.) This article belongs to the collection Genomics for Australian Plants.

Elias Magnus Fries's fungus exsiccati Scleromyceti Sueciae documents specimens cited in several of Fries's publications that are now considered sanctioning works in the nomenclature and taxonomy of several groups of fungi. The first eight fascicles of the first edition of the Scleromyceti Sueciae were issued periodically during the years 1819–1822. Each fascicle was issued as a bound booklet that included, among other information, a printed title page with a date, and an index followed by 30–40 specimens. A ninth fascicle that concluded the first edition was issued without a date. Scholars of the Scleromyceti Sueciae inferred an approximate date of issuance of mid‐1825 based on Fries's correspondence, but they were uncertain whether fascicle nine was issued as a booklet or on loose sheets. In addition, the location of the printed index to fascicle nine that they studied was unclear. We obtained images of a complete, original copy of fascicle nine from the collections of the Natural History Museum of Denmark of the University of Copenhagen. This copy proves that fascicle nine was issued as a bound booklet like the previous eight fascicles and contained a printed index and printed specimen labels. Because of the apparent rarity of a complete, original copy of fascicle nine, we describe the copy at the Natural History Museum of Denmark and provide images of the index. We discuss potential problems in typifying names from material issued in the Scleromyceti Sueciae second edition. Using an example from fascicle nine, we discuss Fries's omissions, errors, and lapses in citing specimens. [ABSTRACT FROM AUTHOR]

- Abstract
To further develop the module German for Migrant Students (DSSZ) which is an inherent part at university teacher education in North Rhine-Westphalia, for example by providing more learning opportunities, a status quo of the module must be determined and described. Due to the tense relationship created by the framework conditions of the module (target group, scope etc.), the question arises how the teacher educators in the module deal with these requirements, which factors they focus on, and which group-specific similarities and differences result from this. In problem-centered interviews with twenty teacher educators in the module at two universities A and B, a qualitative content analysis reveals subject-specific group differences. The subsequent typification provides indications that the educators primarily act in a very individual- and target-group-specific manner. At the same time, they find themselves in a framework in which they must constantly make decisions evoked by the narrowly defined module framework. [ABSTRACT FROM AUTHOR]

Residual lignocellulosic biomass (RLB) is a valuable resource that can help address environmental issues by serving as an alternative to fossil fuels and as a raw material for producing various value-added molecules. To gain a comprehensive understanding of the use of lignocellulosic waste in South America, a review was conducted over the last 4 years. The review focused on energy generation, biofuel production, obtaining platform molecules (such as ethanol, hydroxymethylfurfural, furfural, and levulinic acid), and other materials of interest. The review found that Brazil, Colombia, and Ecuador had the most RLB sources, with sugarcane, oil palm, and rice crop residues being the most prominent. In South America, RLB is used to produce biogas, syngas, hydrogen, bio-oil, biodiesel, torrefied biomass, pellets, and biomass briquettes. The most studied and produced value-added molecule was ethanol, followed by furfural, hydroxymethylfurfural, and levulinic acid. Other applications of interest that have been developed with RLB include obtaining activated carbon and nanomaterials. Significant progress has been made in South America in utilizing RLB, and some countries have been more proactive in regulating its use. However, there is still much to learn about the potential of RLB in each country. This review provides an updated perspective on the typification and valorization of residual biomass in South America and discusses the level of research and technology being applied in the region. This information can be helpful for future research on RLB in South America. [ABSTRACT FROM AUTHOR]

The nomenclatural status and typification of the names Arthrocaulon macrostachyum, Salicornia fruticosa, S. fruticosa var. deflexa, S. fruticosa var. glaucescens, S. fruticosa var. intermedia, S. fruticosa var. humilis, S. fruticosa var. pachystachya, S. fruticulosa, S. glauca, S. lignosa, S. macrostachya var. virescens, S. macrostachya var. glaucescens, S. perennis, S. radicans, S. radicans var. caespitosa, S. sarmentosa, S. sempervirens, and S. virginica, as well as an unnamed β-variety of S. fruticosa proposed by A. Bertoloni, are investigated. Concerning A. macrostachyum, we document that the type indicated in literature (G00177362) is not a holotype, and that lectotypification is necessary. A specimen from G (G00687638) is here designated as a lectotype. On the level of variety, Arthrocnemum fruticosum var. macrostachyum is an earlier legitimate name for Salicornia fruticosa var. pachystachya. Furthermore, Piirainen et al. are incorrect when citing Forsskål's "Salicornia" from Alexandria as "S. virginica Forssk."; it is not a new name and should be cited as S. virginica auct. non L., as published in Forsskål's Flora Aegyptiaco-Arabica. Like with numerous other parallel cases in Flora Aegyptiaco-Arabica, Forsskål's designation of "Salicornia virginica" for an Arabian plant is to be considered a misapplication of the earlier Linnaean name for an American plant. Arthrocnemum glaucum (a nomen illegitimum of Ungern-Sternberg), was listed as type species of Arthrocnemum by the Names in Current Use project; the basionym, Salicornia glauca Delile, is here lectotypified and identified as Arthrocaulon meridionale, published by Ramirez et al. Updated synonymies of Arthrocaulon macrostachyum, A. meridionale, Salicornia fruticosa, and S. perennis are proposed. Salicornia sempervirens is an invalid name according to Art. 36.1a of ICN. No original material was found for S. radicans var. caespitosa. This paper also refer to lecto- or neotypifications on specimens deposited at BM, G, LINN-HS, LY, MPU, NAP, and PAL, and their current taxonomic positions are suggested in a taxonomic part of the paper.

Botanical surveys carried out during the last 13 years throughout central and northern Tunisia (North Africa) allow to find first national and continental N-African records of non-native taxa belonging to Bignoniaceae. The genera Catalpa, Podranea, and Tecomaria are new for N-Africa (Catalpa is new for the whole Africa). Tecomaria capensis is here considered as a naturalized alien species, whereas Campsis radicans, Catalpa bignonioides, Jacaranda mimosifolia, Podranea brycei, P. ricasoliana, and Tecoma stans are casuals. Distribution in Tunisia, phenology, and original photographs are provided for each species. A diagnostic key for Tunisian Bignoniaceae is also given. Moreover, the name Tecoma ricasoliana (basionym of Podranea ricasoliana) is lectotypified on a specimen preserved at K (isolectotypes at FI), whereas the holotype indication of the name Bignonia capensis (basionym of Tecomaria capensis), made in Flora of Tropical East Africa, is here corrected according to the Art. 9.10 of Shenzhen Code (lectotype at UPS; isolectotype, here reported for the first time, at LD).

A taxonomic and nomenclatural account on taxa of Iridaceae proposed by Ferdinand Schur, a famous investigator of the flora of Transylvania (present‐day Romania), is presented. Types are designated for 12 names, namely lectotypes for Crocus banaticus var. niveus, C. exiguus, Iris fieberi var. monantha, I. × binata, I. × cucullata, I. pseudocyperus, I. transsilvanica, I. sibirica var. salina, and neotypes for C. banaticus var. concolor, C. banaticus var. pictus, C. banaticus var. versicolor and I. pumila var. albiflora. Based on a broad examination of Schur's original and authentic material, the taxonomic application of these names, as well as of his invalidly published and unpublished names (appearing only on herbarium labels), are clarified. It is proposed to treat I. fieberi var. monantha as a taxonomic synonym of I. aphylla, I. pumila var. albiflora and I. transsilvanica as synonyms of I. pumila, and I. sibirica var. salina as a synonym of I. spuria. The names I. × binata and I. × cucullata are accepted for the hybrids I. aphylla × pumila and I. × germanica × pallida, respectively. The treatment of I. pseudocyperus as a distinct subspecies within I. graminea is supported. All names validly published by Schur in Crocus are treated as synonyms of C. heuffelianus s.l. until an adequate taxonomic revision covering the southern Carpathian allotetraploid C. cf. heuffelianus (2n = 18) is implemented. If this polyploid deserves the rank of a distinct species, the name C. exiguus, which seems to be the earliest validly published, should be accepted for this taxon. [ABSTRACT FROM AUTHOR]

GREY literature ,BOTANY ,BOTANICAL nomenclature ,PRIMROSES ,HERBARIA ,SYNONYMS ,ASTERACEAE - Abstract
The taxonomic history, nomenclature and application of the oldest species names available for the common hybrids between Pilosella caespitosa and P. lactucella are reviewed. Elias Fries created a nomenclatural and bibliographical collision when he replaced a printed label of his exsiccata Herbarium normale with its second version, distributed at a later date, in which the protologue of Hieracium suecicum had appeared. In this protologue, the new species name was validly published with a mere reference to the original description of H. auricula var. majus, thus being based on the type of the latter. In a later fascicle of the same exsiccata, Fries excluded this synonym and distributed a different morphotype of H. suecicum, which caused taxonomic confusion and re-description of the same taxon under the name H. fennicum. The surviving original material of H. auricula var. majus is rejected, and its neotype is designated, making H. suecicum the correct name for the hybrids strictly intermediate between P. lactucella and P. caespitosa. Such hybrids constitute the most common hybridogenous taxon of Pilosella in Scandinavia, Finland and neighbouring Russia, with many synonyms described from this area and partly typified here. Another hybridogenous taxon of the same origin, more similar to P. lactucella and previously known as P. cochlearis, is correctly named P. stipitiflora comb. nov. The nomenclatural value and bibliographic complexity of exsiccata, a commonly underestimated kind of grey literature in taxonomic botany, are further highlighted. [ABSTRACT FROM AUTHOR]

The unicellular green alga Oophila amblystomatis was named by Lambert in 1905 based upon its association with egg masses of the spotted salamander Ambystoma maculatum. We collected algal cells from Lambert's original egg capsule preparations that were contributed to Phycotheca Boreali‐Americana (PBA) in 1905 and subjected them to DNA extraction and PCR with O. amblystomatis‐specific 18S rRNA gene primers. DNA amplified from these preparations was cloned and nine clones were sequenced. Along with representative sequences from the Oophila clade and Chlorophyceae, a phylogenetic tree was inferred. Seven sequences clustered within the Oophila clade and two clustered with Chlamydomonas moewusii, which is included in a sister clade to Oophila. By sequencing algal material from the egg capsules of representative type material we can unambiguously characterize O. amblystomatis and define a monophyletic clade centered on this type material. Accordingly, we reject a recent proposal that this species be transferred to Chlorococcum. [ABSTRACT FROM AUTHOR]

The South American central Andes have a great richness of Asteraceae, where the genus Stevia (Eupatorieae, Piqueriinae) is also especially diverse. The taxonomy of Stevia species in the southern part of the central Andes pose a challenge because of the unclear delimitation among the species and overlap of morphological characters. Two species complexes were identified for the region comprising north Argentina and southern Bolivia. In this study, our objectives were to employ morphometric analyses to assess the delimitation of taxa within the Stevia alpina Griseb. and Stevia chamaedrys Griseb. complexes. We aimed to identify informative morphological characters and gain insight into the identity of species in each group. To accomplish this, we utilised cluster analysis, principal-component analysis, non-metric multidimensional scaling and univariate analyses to evaluate 37 morphological traits. In total, 200 specimens were examined, covering the entire geographic distribution of each species complex. We found support for the recognition of nine species: Stevia alpina, S. breviaristata Hook. & Arn., S. chamaedrys, S. mandonii Sch. Bip., S. mercedensis Hieron., S. minor Griseb., S. potrerensis Hieron., S. procumbens Hieron. and S. vaga Griseb. A new combination and status is proposed for S. tarijensis Hieron., incorporating it as a variety of S. mandonii, and S. centinelae Cabrera and S. crassicephala Cabrera are merged as synonyms under the name S. alpina. Two neotypes are designated for the names S. mercedensis and S. potrerensis. [ABSTRACT FROM AUTHOR]

PHYLOGENY , *ROSACEAE , *LOQUAT - Abstract
This study addresses the longstanding absence of a comprehensive phylogenetic backbone for the apple tribe Maleae, a deficiency attributed to limited taxon and marker sampling. We conducted an extensive taxon sampling, incorporating 563 plastomes from a diverse range of 370 species encompassing 26 presently recognized genera. Employing a range of phylogenetic inference methods, including RAxML and IQ-TREE2 for Maximum Likelihood (ML) analyses, we established a robust phylogenetic framework for the Maleae tribe. Our phylogenomic investigations provided compelling support for three major clades within Maleae. By integrating nuclear phylogenetic data with morphological and chromosomal evidence, we propose an updated infra-tribal taxonomic system, comprising subtribe Malinae Reveal, subtribe Lindleyinae Reveal, and subtribe Vauqueliniinae B.B.Liu (subtr. nov.). Plastid phylogenetic analysis also confirmed the monophyly of most genera, except for Amelanchier, Malus, Sorbus sensu lato, and Stranvaesia. In addition, we present a comprehensive taxonomic synopsis of Photinia and its morphological allies in the Old World, recognizing 27 species and ten varieties within Photinia, three species and two varieties within Stranvaesia, and two species and three varieties within Weniomeles. Furthermore, we also lectotypified 12 names and made two new combinations, Photinia microphylla (J.E.Vidal) B.B.Liu and Weniomeles atropurpurea (P.L.Chiu ex Z.H.Chen & X.F.Jin) B.B.Liu.

Alexander A. Tatarinow (1817?–1886) made an extensive collection of vascular plants and insects in North China and Mongolia while serving as a physician in the 12th Russian Orthodox Ecclesiastical Mission in Beijing during 1841–1850. Tatarinow's plant collection included about 800 species and became the basis for 70 new species, of which 12 were named after him. The collection was split into three large sets, each labelled in its own way and handled in different times by different people at different institutions, thus obscuring its correct attribution; notable misinterpretations include its misattributions to A. von Bunge and P.E. Kirilov who were attached to the 11th Mission and collected plants near Beijing during 1830–1840. In this study, the history of these three sets and their parts is uncovered, and label samples are provided and commented to allow unambiguous recognition of the sets for correct lectotypification of plant species names based on the material collected by the 11th and 12th Missions.

BOTANY ,FLOWERS ,SPECIES - Abstract
The typification of the Linnaean name Statice echioides (currently Limonium echioides) is discussed. An illustration from Magnol's Botanicum Monspeliense ("Limonium minus annuum bullatis foliis vel echioides") was correctly designated as lectotype by Erben in 1978 according to Art. 7.11 of Shenzhen Code. However, this image lacks some of the important flower characters required for a critical identification of the species. An epitype (plate no. 299 in Sibthorp & Smith's Flora Graeca) is selected to serve as an interpretative type of the lectotype of S. echioides (Art. 9.6). In addition, the name S. aristata, published in Sibthorp & Smith's Flora Graecae prodromus, is discussed in depth and lectotypified on the above‐mentioned Magnol illustration, making this name homotypic with the Linnaean one. Finally, the concept of S. echioides, as described in Flora Graecae prodromus, is discussed, concluding that it refers to the currently recognized Limonium roridum (≡ S. rorida, as originally published in Flora Graeca).

DISCOURSE , *JUDGES , *STANDARDS - Abstract
How do civic groups judge what issues are appropriate for public discourse? And how do they know what kinds of arguments to use where? Cultural sociologists identify varying "orders of worth," that is, historically defined systems of typification and evaluation people draw on to evaluate public arguments. Yet it remains unclear how these take form in ongoing group practices. This article theorizes how groups' ongoing interaction patterns, or "style," typify social scenes to steer members toward distinct orders of worth in varying situations. As I argue, different typifications of public and private scenes condition the type of arguments members deem appropriate for public discourse, with meaningful implications for their politics. Combining style and orders of worth allows us to ask how ostensibly similar groups may publicly define different political goals and value varying forms of civic engagement. I illustrate this theoretical framework with an ethnographic study of two culturally distinct groups of libertarians in the United States. [ABSTRACT FROM AUTHOR]

INDIGENOUS species , *ASTERACEAE , *PHYLOGENY - Abstract
Tribe Anthemideae (Asteraceae) is represented in Australia by only nine indigenous species of Cotula and Leptinella. The generic placement of Cotula alpina (Hook.f.) Hook.f. is considered problematic, because it shares the stoloniferous and scapose habit of Leptinella, but lacks corollas in female florets, a trait traditionally considered defining of Cotula. A previous phylogenetic analysis of Leptinella using ITS and chloroplast data showed that the species nested in that genus, but some uncertainty remained because of incomplete sequence data and missing cytological information, and no taxonomic change was made. Here, we use target-capture data from three different sequencing initiatives to reconstruct a phylogeny of Australian native and introduced Anthemideae to resolve this outstanding question. We confirm previous results with a high degree of support and formally transfer Cotula alpina to the genus Leptinella. A lectotype is selected for the basionym, Ctenosperma alpinum Hook.f.

SUBSPECIES , *CAMPANULACEAE , *GENETIC variation , *DNA sequencing , *AMPLIFIED fragment length polymorphism - Abstract
Campanula hawkinsiana and C. ramosissima are among the poorly investigated Campanula species distributed in the Balkan Peninsula. According to recent phylogenetic studies these species are closely related, and they belong to the section Decumbentes along with the two species from the Iberian Peninsula. However, none of these published studies included a larger number of populations of C. hawkinsiana and C. ramosissima, nor were they studied in detail at the morphological level. During our floristic investigations in the Balkan Peninsula, we observed a great morphological variability within the populations of C. ramosissima. The most morphologically specific and diverse are C. ramosissima populations from Montenegro. Considering all this, in this study, both molecular (AFLP fingerprinting and DNA sequencing) and classical morphometric analyses were applied with the aim to get insight into the genetic diversity and morphological variability of the populations from Montenegro and geographically close populations of both species from the section Decumbentes in the western part of the Balkan Peninsula. Significant morphological differences and a distinct position based on molecular phylogenetic evidence indicate that the plants from Montenegro should be recognized as a new subspecies, described here as Campanula ramosissima subsp. megapetala subsp. nov.

The Salvador herbarium (seventeenth to eighteenth century) is one of the oldest pre-Linnaean herbaria in Spain. Currently preserved in the Botanical Institute of Barcelona, it was reviewed by Pourret during the eighteenth century, who added the Linnaean name of the species to the labels and proposed many new names. Our study has allowed us to enlist all taxa proposed by Pourret (a total of 335); however, only 12 were validly published (some by other authors), and two of them are lectotypified here. We have also classified the rest of names into three categories: 35 that were included in publications by other authors but are not validly published names; 160 that were published by other authors; and 128 that we have not been able to find in any publication, and they should be considered as merely Pourret's proposals without any validity. These results reflect the situation of plant taxonomy in the late eighteenth century; in Pourret's time the number of published taxa was very low while taxonomical studies done by other contemporary authors were rarely available. Thus, Pourret was not able to assign already published taxa to all specimens and, therefore, he was forced to do new proposals that were mostly incorrectly published. [ABSTRACT FROM AUTHOR]

BOTANY , *SECTS , *SYNONYMS , *SPECIES - Abstract
A few species names in Cytisus sect. Tubocytisus are re-assessed and taxonomically evaluated. Diagnostic characters are discussed and the species status of C. absinthioides Janka, C. eriocarpus Boiss., C. frivaldszkyanus Degen, C. jankae Velen. and C. smyrnaeus Boiss. is confirmed. The holotype of Cytisus triflorus Lam. was found to belong to C. hirsutus L. rather than to the C. ratisbonensis group as currently treated. Cytisus lasiosemius Boiss. is not the correct name for C. frivaldszkyanus Degen, but another synonym of C. hirsutus. Cytisus litwinowii V.I.Krecz., which was known solely from the holotype, is a synonym of C. austriacus L. s.str. Chamaecytisus pseudojankae Pifkó & Barina, reported from a small area shared between Albania, Greece and North Macedonia, is treated as a subalpine variant of C. austriacus. Cytisus tmoleus Boiss. is removed from the synonymy of C. eriocarpus and added to the synonymy of C. pygmaeus Willd. Cytisus falcatus subsp. albanicus Degen & Dörfl. and C. pubescens Gilib. are synonymised with C. hirsutus. Cytisus microphyllus Boiss. is moved from C. austriacus s.l. to the synonymy of C. frivaldszkyanus, and C. pindicola (Degen) Halácsy to the synonymy of C. jankae. Chamaecytisus calcareus (Velen.) Kuzmanov is accepted as Cytisus calcareus (Velen.) Sennikov & Val.N.Tikhom., comb. nov., and its distribution is circumscribed. Cytisus hirsutus var. ciliatus (Wahlenb.) Hazsl. and C. polytrichus var. subglabratus Val.N.Tikhom. & Sennikov, var. nov. are recognised as glabrous variants of the corresponding species. Lectotypes of C. ciliatus, C. hirsutissimus K.Koch, C. jankae, C. lasiosemius, C. pubescens, C. rhodopeus J.Wagner ex Bornm. and C. thirkeanus K.Koch are designated. Cytisus polytrichus is reported from the Western Caucasus in place of C. wulffii auct. [ABSTRACT FROM AUTHOR]

A group of species of Cytisus sect. Tubocytisus with strictly lateral inflorescences, commonly referred to as C. ratisbonensis s.l., is critically revised in Eastern Europe on the basis of morphology and comprehensive treatment of herbarium specimens and observations. Seven species and two presumed hybrids are recognised. Complete accounts are provided for each species, with synonyms, typifications, brief morphological descriptions, data on ecology and distributions, taxonomic and nomenclatural annotations. Cytisus polonicus is described as new to science, separated from C. ratisbonensis on the basis of morphology and diploid (vs. tetraploid) chromosome count. The lectotype of C. elongatus is superseded and a new lectotype is designated; this name has priority for the species previously known as C. triflorus. Six species names are newly placed to the synonymy: Chamaecytisus pineticola under Cytisus ruthenicus s. str., and Cytisus czerniaevii, C. leucotrichus, C. lindemannii, C. ponomarjovii and Chamaecytisus korabensis under Cytisus elongatus. The presumed hybrid between C. ruthenicus and C. elongatus, which was incorrectly known as C. czerniaevii, is described here as C. semerenkoanus. Cytisus lithuanicus, which has been an obscure name since its original publication, is resurrected for a newly-recognised octoploid species, which is endemic to eastern Poland, western Belarus and north-western Ukraine. The name C. cinereus is re-instated for the species previously known as C. paczoskii, and C. horniflorus is added to its synonymy; its complete distribution area is circumscribed, and its occurrence in Austria, Poland, Romania, Serbia and Slovakia is documented. Cytisus kreczetoviczii and C. elongatus are reported for the first time from Belarus, and the latter species also from Bosnia and Herzegovina, Montenegro and Slovenia. Cytisus borysthenicus and C. elongatus are reported as new to some territories in European Russia. Cytisus ratisbonensis s. str. is treated as absent from Eastern Europe. The neglected protologue of C. ruthenicus is discovered, and the nomenclature of all other names is verified and corrected when necessary. The original material of C. borysthenicus is re-discovered. Five further lectotypes and one neotype are designated. Distribution areas are circumscribed on the basis of numerous herbarium collections and documented observations, identified or verified by the authors. Chromosome counts published for nameless taxa from Belarus, Ukraine and Russia are assigned to the species according to their herbarium vouchers: C. borysthenicus, C. kreczetoviczii and C. lithuanicus are octoploid (2n = 100), C. ruthenicus is tetraploid (2n = 50) and octoploid (2n = 100), and C. semerenkoanus and C. elongatus are tetraploid (2n = 50).

The typification of the name Atriplex mollis, validly published by R. L. Desfontaines in Flora Atlantica, is discussed. A specimen deposited at G (barcode G00386803) is designated as the lectotype of the name. The distribution in Europe of the species is also discussed. It was indicated for Sardinia only (Italy, Southern Europe) in a single locality (San Paolo pond, Cagliari Province). No specimen that proves the occurrence of the species in Sardinia is in extant. Moreover, the overlapping of a map published in 1912 and the current satellite images, allowed to verify that the area in which A. mollis grew up, including wetlands at the beginning of the XX century, is currently almost totally covered by buildings and commercial/industrial sites. In other words, the habitat where the species occurred was destroyed. As a consequence, at the current state of knowledge, the species is here assessed as extinct (EX) at national level according to the IUCN categories.

ABSTRACT Manihot includes about 150 species with a Neotropical distribution. Wild species of Manihot constitute a plant genetic heritage that can be used in breeding programs for the cultivable species Manihot esculenta Crantz (cassava). However, wild populations, especially endemic ones, are under constant threat due to habitat destruction and climate change. The objective of this manuscript was to elaborate a taxonomic treatment of the endemic species of Manihot recorded in Northeast Brazil; determine the geographical distribution of species, richness, their conservation status, and solve typification problems. The study was based on the analysis of specimens deposited in national and international herbaria, as well as on field observations. Fifteen endemic species of Manihot were found, we propose lectotypes for five of them and one neotype. Most species are distributed in the state of Bahia, growing in Caatinga, Cerrado, and Atlantic Forest environments. Only M. breviloba was found in the states of Sergipe and Alagoas. The richest area was found in the Chapada Diamantina of the Espinhaço Range. In terms of conservation status, 80% of endemic species are in some threatened category, 13% are in the near threatened category and only 7% are in the least concern category.

Lack of data regarding the agricultural activities in the area of Imués (Nariño, Colombia) has hindered understanding of current land uses and their impacts on natural resources, which causes this area to be considered one of the most arid in the region. To comprehend these processes, a description of the main land uses and agricultural and livestock production systems was made. This was carried out from a social, economic, and environmental dynamic through the characterization and typification of farms. Groups or clusters were constructed, which were previously subjected to qualitative statistical analysis, using the multiple correspondence factor analysis (MCAF) method. Subsequently, the hierarchical classification method was applied. The MCAF was able to establish four factors that were framed in the interaction of climate, altitude, and the productive component associated with it. Similarly, taking into account the social, economic, and environmental perspectives, it was determined that these groups, under their particularities and agricultural vocations, exert pressure on the territory's strategic ecosystems and diversity of flora and fauna. This makes their rural activities unsustainable. It was also found that there is a vocation for livestock exploitation and some minor species in the middle and high-altitude zones of the territory. However, it was established for other groupings that their major typologies were associated with conventional management without any planning. This generates negative impacts on soil resources, such as erosion and forest fragmentation, together with the expansion of the agricultural frontier.

In 1885 Lojacono-Pojero described Cistus skanbergi, also known as the dwarf pink rockrose, from the Island of Lampedusa (Sicily, Italy). Despite becoming extinct in its type locality and being very rare in the Mediterranean Basin, during the last decades the plant corresponding to this name, a natural hybrid between C. parviflorus Lam. and C. monspeliensis L., has been successfully cultivated and introduced worldwide for ornamental purposes. The search carried out in several European herbaria allowed to select as lectotype a specimen collected by Lojacono-Pojero and kept at the herbarium of Kew, to detect other isolectotypes, kept in the herbaria of Geneva and Palermo, and to detect another syntype corresponding to a specimen collected by Gussone and currently kept at the herbarium of Palermo.

Nicolas Alexander Dalzell (1817–1878) described seven species of Lepidagathis (Acanthaceae). Except for Lepidagathis grandiflora, which was later recognized as Calacanthus, all are retained in the genus Lepidagathis. Of these, five are endemic to peninsular India. While exploring Dalzell’s species, we have made field explorations, consulted Lepidagathis collection at different herbaria, and presented here a synopsis of the genus in India. The nomenclature, taxonomy, distribution, and The International Union for Conservation of Nature (IUCN) threat status of Lepidagathis species in India are reviewed. Nomenclature and taxonomic notes on L. cristata and L. cuspidata and the infraspecific taxa in L. pungens, L. incurva are provided. Lepidagathis aristata, a Malaysian species is resurrected; a new name Lepidagathis forskaolii is proposed for the oldest basionym Ruellia aristata. Lepidagathis clavata, L. prostrata, and L. rigida are rare, and only known by a few collections, L. lutea is confined to Konkan and adjoining areas. Lepidagathis cuspidata is collected from its entire geographic range and an overlooked variety, L. cuspidata var. stenostegia is resurrected. Based on live and herbarium collections, a riverine, elliptic-linear-leaved variety elliptica is proposed. Lepidagathis dalzellii, a large flowered new species, allied to L. cuspidata from the United Nations Educational, Scientific and Cultural Organization (UNESCO) World Natural Heritage Site (Kaas plateau, Maharashtra) is also described and illustrated.

The genus Podaxis was first described from India by Linnaeus in 1771, but several revisions of the genus have left the taxonomy unclear. Forty-four Podaxis species names and nine intraspecific varieties are currently accepted, but most fungarium specimens are labelled Podaxis pistillaris. Recent molecular analyses based on barcoding genes suggest that the genus comprises several species, but their status is largely unresolved. Here we obtained basidiospores and photographs from 166 fungarium specimens from around the world and generated a phylogeny based on rDNA internal transcribed spacer ITS1, 5.8S and ITS2 (ITS), and a phylogenomic analysis of 3 839 BUSCO genes from low-coverage genomes for a subset of the specimens. Combining phylogenetics, phylogenomics, morphology, ecology, and geographical distribution, spanning 250 years of collections, we propose that the genus includes at least 16 unambiguous species. Based on 10 type specimens (holotype, paratype, and syntype), four recorded species were confirmed, P. carcinomalis, P. deflersii, P. emerici, and P. farlowii. Comparing phylogenetic analysis with described species, including morphology, ecology, and distribution, we resurrected P. termitophilus and designated neotypes, epitypes, or lectotypes for five previously described species, P. aegyptiacus, P. africana, P. beringamensis, P. calyptratus, and P. perraldieri. Lastly, based on phylogenies and morphology of type material, we synonymized three reported species, P. algericus, P. arabicus, and P. rugospora with P. pistillaris, and described five new species that we named P. desolatus, P. inyoensis, P. mareebaensis, P. namaquensis, and P. namibensis.

Carex vulpina and C. otrubae are closely related and morphologically similar species that hybridize with C. remota. The spontaneous appearance of hybrids can cause difficulties in the taxonomic treatment of this group. Morphological separation of the examined species and hybrids had been tested using discriminant function analysis (DFA). We have also analysed the effect of DNA barcoding on hybrid identification from the perspective of machine learning approach (MLA). Hybrids were investigated in terms of three barcodes sequence (ITS , matK , rbcL) by means of the BLOG and WEKA (MLA). Our results provide the first insights into the morphological and genetic relationships between the studied species and their hybrids. Morphological analysis showed traits useful in the identification of hybrids, i.e. dark brown usually fibrous basal sheaths and a dorsally split beak in Carex remota × C. vulpina (inherited from C. vulpina), distinctly separated spikes, and a long bract in C. otrubae × C. remota (inherited from C. remota). Phylogenetic analysis also indicated a close relationship of Carex remota × C. vulpina with C. vulpina and C. otrubae × C. remota with C. remota. Moreover, we have presented here nomenclatural notes on the hybrids and typified the names Carex × crepinii [ C. otrubae × C. remota ] and Carex × kernii [ Carex remota × C. vulpina ].

TAMARISKS ,SOIL salinity - Abstract
Tamarix is native to Eurasia plus the northern and southern territories of Africa, with some species being introduced into America and Oceania. They are usually found in arid, desertic, or subdesertic areas, often on saline or subsaline soils, in Mediterranean, temperate, or subtropical climates. The genus is renowned for its complex taxonomy, which is usually based on rather variable or unstable characters, which leads to contrasting taxonomic treatments. As part of the taxonomic revision of Tamarix undertaken by the authors, ten names (i.e., T. africana, T. bounopoea, T. brachystylis var. fluminensis, T. malenconiana, T. muluyana, T. tenuifolia, T. tingitana, T. trabutii, T. valdesquamigera, and T. weyleri) published from material collected in the southwestern parts of the Mediterranean basin are taxonomically and nomenclaturally discussed after analysing their original material. Eight intended holotypes are corrected here to lectotypes; one epitype is designated for T. africana to warrant current use of the name; and one isotype, 30 isolectotypes, and 11 syntypes are also identified for the studied names. Further, the taxonomic identity of all names and their eventual synonymic placement are accordingly discussed. [ABSTRACT FROM AUTHOR]

Many members of the Oomycota genus Phytophthora cause economic and environmental impact diseases in nurseries, horticulture, forest, and natural ecosystems and many are of regulatory concern around the world. At present, there are 223 described species, including eight unculturable and three lost species. Twenty-eight species need to be redescribed or validated. A lectotype, epitype or neotype was selected for 20 species, and a redescription based on the morphological/molecular characters and phylogenetic placement is provided. In addition, the names of five species are validated: P. cajani, P. honggalleglyana (Synonym: P. hydropathica), P. megakarya, P. pisi and P. pseudopolonica for which morphology and phylogeny are given. Two species, P. ×multiformis and P. uniformis are presented as new combinations. Phytophthora palmivora is treated with a representative strain as both lecto- and epitypification are pending. This manuscript provides the updated multigene phylogeny and molecular toolbox with seven genes (ITS rDNA, ß-tub, COI, EF1a, HSP90, L10, and YPT1) generated from the type specimens of 212 validly published, and culturable species (including nine hybrid taxa). The genome information of 23 types published to date is also included. Several aspects of the taxonomic revision and phylogenetic re-evaluation of the genus including species concepts, concept and position of the phylogenetic clades recognized within Phytophthora are discussed. Some of the contents of this manuscript, including factsheets for the 212 species, are associated with the "IDphy: molecular and morphological identification of Phytophthora based on the types" online resource (https://idtools.org/tools/1056/index.cfm). The first version of the IDphy online resource released to the public in September 2019 contained 161 species. In conjunction with this publication, we are updating the IDphy online resource to version 2 to include the 51 species recently described. The current status of the 223 described species is provided along with information on type specimens with details of the host (substrate), location, year of collection and publications. Additional information is provided regarding the ex-type culture(s) for the 212 valid culturable species and the diagnostic molecular toolbox with seven genes that includes the two metabarcoding genes (ITS and COI) that are important for Sanger sequencing and also very valuable Molecular Operational Taxonomic Units (MOTU) for second and third generation metabarcoding High-throughput sequencing (HTS) technologies. The IDphy online resource will continue to be updated annually to include new descriptions. This manuscript in conjunction with IDphy represents a monographic study and the most updated revision of the taxonomy and phylogeny of Phytophthora, widely considered one of the most important genera of plant pathogens.

A Special‐purpose Committee on DNA Sequences as Types was established at the XIX International Botanical Congress (IBC) in Shenzhen, China in 2017, with a mandate to report to the XX IBC with recommendations on a preferred course of action with respect to DNA sequences as potential types under the International Code of Nomenclature for algae, fungi, and plants. This report provides a synthesis of the deliberations from the Special‐purpose Committee on this issue. We discuss two potential options for dealing with the problem that many species, especially of microfungi and microalgae, can be discovered and delimited using eDNA sequencing but cannot currently be formally named due to the requirement in the Code that either a specimen or illustration be nominated as holotype. One option is to expand the definition of "type" to include DNA sequences, while a second option would allow some taxa to be named without types, the application of their names instead being determined using a DNA sequence. This report should be read in concert with two formal proposals for potential amendments to effect these options, published in this issue of Taxon. [ABSTRACT FROM AUTHOR]

A special‐purpose Committee on DNA Sequences as Types was established at the XIX International Botanical Congress (IBC) in Shenzhen, China, in 2017, with a mandate to report to the XX IBC in Madrid in 2024 with recommendations on a preferred course of action with respect to potential amendments of the International Code of Nomenclature for algae, fungi, and plants to allow DNA sequences as types. This is the first in an expected series of papers from the Special‐purpose Committee on this issue. We set out the background to the establishment of the Committee, explore key issues around typification that are pertinent to the question of DNA sequences as types, enumerate pros and cons of allowing DNA sequences as types, and foreshadow options for future discussion and potential recommendations.

The unambiguous application of fungal names is important to communicate scientific findings. Names are critical for (clinical) diagnostics, legal compliance, and regulatory controls, such as biosafety, food security, quarantine regulations, and industrial applications. Consequently, the stability of the taxonomic system and the traceability of nomenclatural changes is crucial for a broad range of users and taxonomists. The unambiguous application of names is assured by the preservation of nomenclatural history and the physical organisms representing a name. Fungi are extremely diverse in terms of ecology, lifestyle, and methods of study. Predominantly unicellular fungi known as yeasts are usually investigated as living cultures. Methods to characterize yeasts include physiological (growth) tests and experiments to induce a sexual morph; both methods require viable cultures. Thus, the preservation and availability of viable reference cultures are important, and cultures representing reference material are cited in species descriptions. Historical surveys revealed drawbacks and inconsistencies between past practices and modern requirements as stated in the International Code of Nomenclature for Algae, Fungi, and Plants (ICNafp). Improper typification of yeasts is a common problem, resulting in a large number invalid yeast species names. With this opinion letter, we address the problem that culturable microorganisms, notably some fungi and algae, require specific provisions under the ICNafp. We use yeasts as a prominent example of fungi known from cultures. But viable type material is important not only for yeasts, but also for other cultivable Fungi that are characterized by particular morphological structures (a specific type of spores), growth properties, and secondary metabolites. We summarize potential proposals which, in our opinion, will improve the stability of fungal names, in particular by protecting those names for which the reference material can be traced back to the original isolate.

This study applied qNMR spectroscopy and chemometrics to metabolically profile polyfloral honey samples collected in southeastern (São Paulo - SP) and southern (Santa Catarina - SC) Brazil, over the 2019–2020 and 2020–2021 harvest seasons. Both 1D and 2D NMR experiments were carried out to identify and quantify metabolites, followed by descriptive statistical analysis, heatmap, and principal component analysis (PCA), considering geographic and botanical origins. Twenty-one metabolites were detected, encompassing carbohydrates, amino acids, organic acids, ketones, alcohols, esters, and alkaloids. The heatmap and the PCA allowed for distinguishing the geographical and botanical origin. Regarding the botanical origin, three clusters were detected, i.e., Hovenia dulcis (SC), Citrus spp. (SP), and Eucalyptus spp. (SC and SP). The analytical approach proved to be effective for determining the geographic and botanical origins of Brazilian polyfloral honey, even though the country has a huge floral diversity and, accordingly, different types of honey.

The genus Erythrophleum Afzel ex R.Br. is revised for Australia and three species are recognised, all previously included in E. chlorostachys (F.Muell.) Baill. Erythrophleum arenarium R.L.Barrett & M.D.Barrett is described as a new species to accommodate populations from desert sands of the Great Sandy Desert and Dampier Botanical Districts in north-western Australia, parapatric to the remaining species. Erythrophleum pubescens R.L.Barrett & M.D.Barrett is described as a new species spanning tropical Australia, and is sympatric with E. chlorostachys sensu stricto in the Northern Territory and adjacent areas of Western Australia and Queensland. Morphological examination has shown these three taxa to be consistently distinct across their respective ranges. Analyses of the nuclear ribosomal ITS1 region recovered three well-supported clades corresponding to the three morphologically defined species, and ITS1 has utility as a marker to separate sterile specimens. Erythrophleum pubescens is widespread in the Australian Monsoon Tropics, from the coast of Western Australia, near Derby, to Cape York Peninsula in northern Queensland. Erythrophleum chlorostachys is also widespread, from the eastern Kimberley Region, in Western Australia, to the Gulf of Carpentaria, in northern Queensland. A lectotype is chosen for Laboucheria chlorostachya F.Muell. Full descriptions, illustrations of key features and identification keys are provided for the three Australian species. A summary of the significant utilisation of Erythrophleum species is presented. [ABSTRACT FROM AUTHOR]
