Background and Aims: Wurdastom is a little-known neotropical genus, which is poorly represented in herbarium collections. A historical summary,discussion about the tribal position, taxonomic review, and a conservation assessment of each species of the genus was carried out.Methods: Wurdastom specimens of 17 herbarium collections from Colombia (CAUP, COAH, COL, CUVC, FMB, HUQ, PSO, UDBC, UPTC, VALLE), Ecuador (QCA, QCNE), and the United States of America (CAS, F, MO, NY, US) were reviewed, and relevant type collections available at JSTOR Global Plants were consulted. An identification key, descriptions, illustrations and distribution maps for each species were developed. IUCN guidelines and criterio were used for conservation assessments of each species.Key results: In total, 52 Wurdastom collections were found in the revised herbaria. A new species from Colombia is described and new isotypes from the VALLE Herbarium are reported here for the first time. Wurdastom is a small genus of trees and shrubs from central-west Colombia to northern Peru where it grows in Andean and humid lowland tropical forests. The genus, which is assigned to the tribe Cyphostyleae, is characterized by the acrodromous venation, barbellate trichomes on vegetative parts and inflorescences, multiflorous thyrsoid or pleiothyrsoid inflorescence, haplostemonousflowers, petals ≤1 cm long, inferior ovaries, and capsular fruits.Conclusions: Wurdastom includes eight neotropical species, most of them with restricted distributions. One species is assessed here as Threatened (W. sneidernii), two as Vulnerable (W. cuatrecasasii, W. dudleyi), and the rest are treated as Data Deficient.

A taxonomic revision of the genus Scleria (Cyperoideae, Cyperaceae) in Madagascar is presented. Herbarium specimens have been examined and 422 identified to species level. Our results recognise 25 species of Scleria from Madagascar, plus an additional heterotypic variety. Eight species are endemic to Madagascar, two are near endemic, eight taxa are also found on mainland Africa, and eight are widespread tropical taxa. Scleria achtenii is reported from Madagascar for the first time, and S. rosea is accepted at species level instead of being considered as a synonym of S. trialata. Distribution maps, conservation assessments, and notes on synonymy, ecology and ethnobotany are provided. Fourty-seven names are typified. Three rare endemic species: S. andringitrensis, S. madagascariensis and S. perpusilla, are assessed as threatened; and a recently described species, S. ankaratrensis, is indicated as Data Deficient. The most species-rich infrageneric taxa, sections Hypoporum, Abortivae and Foveolidia include 18 taxa in total, and showed strong differences in habitat preference.

A taxonomic revision of Desplatsia Bocq. (Malvaceae s. lat. Juss., subfamily Grewioideae Hochr., tribe Grewieae Endl.) based on about 800 herbarium specimens is presented. Desplatsia is a genus of trees and shrubs found in tropical West and Central Africa and is characterized by subulately divided stipules, the absence of an androgynophore, stamens that are fused to a tube at the base, and large and distinctive fruits that are dispersed by elephants. Four species are recognized (D. subericarpa Bocq., D. chrysochlamys (Mildbr. & Burret) Mildbr. & Burret, D. dewevrei (De Wild. & T.Durand) Burret and D. mildbraedii Burret) and 12 species names are placed into synonymy, two of which have been put into synonymy for the first time: D. floribunda Burret syn. nov. and D. trillesiana (Pierre ex De Wild.) Pierre ex A.Chev. syn. nov. All four species are widely distributed and their conservation status is assessed as Least Concern (LC). A key to the species, full species descriptions, illustrations, a specimen citation list and distribution maps are provided.

A taxonomic revision of Anthriscus (Apiaceae, tribe Scandiceae) in Turkey was carried out. The genus Anthriscus is represented by four sections and eight taxa, including six species with three non-typical infraspecific taxa in that territory, grouped into four sections: i) A. sect. Anthriscus (A. caucalis var. caucalis and A. tenerrima var. tenerrima); ii) A. sect. Cerefolium (A. cerefolium var. trichocarpa); iii) A. sect. Caroides (A. kotschyi); and iv) A. sect. Cacosciadium (A. lamprocarpa subsp. lamprocarpa, A. lamprocarpa subsp. chelikii, A. sylvestris subsp. sylvestris and A. sylvestris subsp. nemorosa). A new taxon, A. lamprocarpa subsp. chelikii, was found and published as a preliminary result of the present revisionary study. Some new characters such as length of filament and petal, and the ratio of fruit length to its beak length are used in the identification key for the first time. New localities of some taxa were found and their distribution areas are expanded. According to all morphological findings on Turkish Anthriscus, a new description of the genus was carried out. The taxonomic treatments for all taxa include type, synonyms (when present), morphological descriptions, phenology, and distribution areas (worldwide and local), habitats, phytogeographic region, conservation assessment and specimens examined. A new identification key for the sections and all Turkish species of the genus Anthriscus is reported, and illustrations and distribution maps in Turkey are also given for eight taxa.

The genus Donella Pierre ex Baill. is here reinstated and Austrogambeya Aubrév. is, for the first time, placed in synonymy based on the findings of recent combined molecular and morphological studies. Seventeen species are recognised, two of which, Donella ranirisonii L.Gaut. & Mackinder and D. humbertii Capuron ex Mackinder & L.Gaut., from Madagascar, are described here for the first time. The flowers of Donella ambrensis and D. delphinensis are described here for the first time, as are the fruits of D. guereliana. Two keys, to the species of Madagascar and tropical Africa, respectively, are presented. Ten species are endemic to Madagascar, six species are endemic to tropical Africa and one, Donella lanceolata, occurs from Madagascar to the Solomon Islands. For each species, the accepted name with synonymy is given, followed by a morphological description. Geographical range and details of habitat are provided, with taxonomic and/or nomenclatural notes as appropriate. Distribution maps are presented for all species, and preliminary conservation assessments are made. Five species qualify for a category of Threat, and three further species are assessed as Near Threatened. An index to species and a list of exsiccatae are included.

Several taxonomic treatments of Styrax (Styracaceae) exist in regional floras of Asia, but the Asian species of the genus have not been comprehensively revised since 1907. A treatment of the Asian taxa of S. series Cyrta with imbricate floral aestivation was accomplished in 2003. To complete the taxonomic revision of S. series Cyrta, we conducted a taxonomic revision of the species of the series with valvate aestivation of the corolla lobes. Our revision comprises 11 species with a combined distribution from eastern India through southern China and Malesia, Melanesia, and Micronesia, although the group is absent from the Philippines. We resurrected S. bracteolatus, S. rubifolius, and S. warburgii as species to be recognized, and we corrected the misapplication of S. finlaysonianus, previously used for a species in S. series Benzoin. Styrax finlaysonianus and S. warburgii are segregated from the broader concept of S. agrestis recognized in prior treatments. The circumscriptions of the heretofore poorly delimited species S. confusus, S. faberi, and S. fortunei are clarified and their possible introgressants discussed. We observed unique combinations of characters in some problematic specimens whose taxonomic status remains unresolved because only single specimens with either flowers or fruits were available; at least some of these may represent undescribed species. Lectotypes are designated for Cyrta agrestis, S. argyi, S. bracteolatus, S. calvescens, S. casearifolius, S. confusus var. microphyllus, S. dasyanthus, S. dasyanthus var. cinerascens, S. faberi, S. finlaysonianus, S. formosanus, S. fortunei, S. fukienensis, S. henryi, S. henryi var. microcalyx, S. iopilinus, S. philadelphoides, S. rostratus, S. rubifolius, S. serrulatus var. agrestis, and S. virgatus. A neotype is designated for S. warburgii. Keys, descriptions, distribution maps, and conservation assessments are provided for all species. Styrax agrestis, S. bracteolatus, and S. rubifolius are rare endemics of conservation concern, with highly restricted distributions.
