A monograph of Curarea, a neotropical genus in the plant family Menispermaceae, is presented. Curarea is distinguished from related genera by the combination of staminate flowers with sepals in two whorls and pistillate flowers with three petals, three carpels and usually elongated carpophores bearing three sessile drupelets. Nine species are recognised, amongst them two new to science, C.gentryana from Ecuador and C.barnebyana, from Ecuador and Peru. Additionally, two new combinations, C.iquitana and C.tomentocarpa, are proposed for distinct taxa recovered in a multivariate analysis of quantitative characters of the broadly distributed and morphologically variable C.toxicofera. The anatomy and morphology of species in the genus is documented, identification key, species descriptions, distribution maps and a preliminary conservation assessment for all accepted species are also provided. Of the nine species recognised here, C.barnebyana is assigned a preliminary status of Vulnerable, C.crassa (known only from the coastal Atlantic Forest in Brazil) and C.gentryana (endemic to western Ecuador) are both assigned a preliminary status of Endangered.

Presented here is a taxonomic revision of the Neotropical palm genus Syagrus (Arecaceae, Arecoideae, Cocoseae, Attaleinae), which is mostly from South America and primarily from Brazil. The history of the genus is reviewed. The revision includes a key, a complete list of synonymy, species descriptions, a list of specimens, distribution maps, color plates, and a conservation assessment of each species. Included herein are 65 species, 2 subspecies, and 14 natural hybrids. Of these palms, one is new (Syagrus pimentae); three are new combinations (S. cataphracta, S. elata, S. × dickensonii); and two have changed their status (S. graminifolia subsp. graminifolia and S. graminifolia subsp. glazioviana). Of the fourteen naturally occurring hybrids, eleven have hybrid names and three do not. This revision is an important contribution to the taxonomy and identification of Syagrus species from South America and the Caribbean, and is the culmination of many years of lab and fieldwork.

Molecular Phylogenetic

A recent molecular phylogenetic study revealed four distinct evolutionary lineages in the genus Costularia s.l. (Schoeneae, Cyperaceae, Poales). Two lineages are part of the Oreobolus clade of tribe Schoeneae: the first being a much-reduced genus Costularia s.s., and the second a lineage endemic to New Caledonia for which a new genus Chamaedendron was erected. The other two lineages were shown to be part of the Tricostularia clade of tribe Schoeneae. Based on morphological and molecular data, the genus Costularia is here redelimited to represent a monophyletic entity including 15 species, which is restricted in distribution to southeastern Africa (Malawi, Mozambique, South Africa, Swaziland, Zimbabwe), Madagascar, the Mascarenes (La Réunion, Mauritius), and the Seychelles (Mahé). Molecular phylogenetic data based on two nuclear markers (ETS, ITS) and a chloroplast marker (trnL-F) resolve the studied taxa as monophyletic where multiple accessions could be included (except for Costularia laxa and Costularia purpurea, which are now considered conspecific), and indicate that the genus dispersed once to Africa, twice to the Mascarenes, and once to the Seychelles. Two endemic species from Madagascar are here described and illustrated as new to science, as is one additional species endemic to La Réunion. Two taxa previously accepted as varieties of Costularia pantopoda are here recognised at species level (Costularia baronii and Costularia robusta). We provide a taxonomic revision including an identification key, species descriptions and illustrations, distribution maps and assessments of conservation status for all species.

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.

This study provides a taxonomic revision for Ceropegia sec. Huernia in the flora of Saudi Arabia. Forty-eight quantitative and qualitative morphological characters were analysed using principal component analysis (PCA), principal coordinates analysis (PCoA) and the unweighted pairs group using mean average (UPGMA) to separate and help delimit taxa. We proposed to reduce the number of names reported in Saudi Arabia from 11 to four species: C. arabica comb. nov.,C. Khalidbinsultanii comb. nov., C. laevis and C. lodarensis. This study also suggested reducing two of Plowes’ new names to a variety level under C. lodarensis (var. foetida comb. nov. and var. rubrosticta comb. nov.). A key to the species, detailed morphological descriptions, illustrations, distribution maps, ecology, etymology and preliminarily conservation assessments following IUCN criteria are provided.
