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.

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.

A taxonomic revision of the Mexican and Central American members of Symplocos is presented. Thirty two species are recognized for the region. Two of the species belong to Symplocos sect. Hopea, and 30 are members of S. sect. Symplocos series Symplocos. The species of S. ser. Symplocos are easily distinguished from those of S. sect. Hopea by their connate petals that are adnate to the androecium distinctly beyond the base (versus connate and adnate at the base only), and filaments that are tangentially flattened in cross section and apically constricted (versus terete and not apically constricted). Of the 32 recognized species, ten are endemic to Mexico, 13 are endemic to Central America, two are shared between Central America and South America, seven are shared between Mexico and Central America, and one is shared among Mexico, Central America, and Cuba. One new species, S. nigridentata, is described from Mexico, and lectotypifications or neotypifications are provided for S. coccinea, S. coccinea var. hirta, S. costaricana, S. hartwegii, S. hartwegii var. opaca, S. limoncillo, S. prionophylla, S. pycnantha, S. schiedeana, S. serrulata, S. speciosa, and S. tomentosa. The revision includes keys, full synonymy, descriptions, illustrations for those species not already illustrated elsewhere, distribution maps and assignment of conservation status for all species, and a complete list of exsiccatae.

A taxonomic monograph of a re-circumscribed Leandra sect. Leandra is presented. The new circumscription is based on a previous phylogenetic hypothesis, and diagnostic morphological characters are discussed. Four new combinations to Leandra are proposed, one from Clidemia (L. capilliflora) and three from Ossaea (L. capitata, L. cogniauxii and L. loligomorpha). Additionally, eight species are treated as synonyms for the first time, and 15 lectotypes are designated. A review of the 17 recognized species, including descriptions, synonymy, illustrations and distribution maps, is provided. This work also includes an overview of general morphology, leaf and flower anatomy, phenology and geographical distribution. Species with a history of taxonomic problems and/or with distinctive morphotypes are further investigated with morphometrics tools.

Dissochaeta is a plant genus of woody climbers, classified in the tribe Dissochaeteae (Melastomataceae). The taxonomic history of the genus is complicated and includes some allied genera like Dalenia, Diplectria, Macrolenes and Omphalopus. Most of them are already regarded as synonyms of Dissochaeta except for Macrolenes which is considered a separate genus here as well. Dissochaeta is characterised by its scrambling habit, interpetiolar outgrowths, 4-merous flowers, dimorphic stamens and berry-like fruits. A taxonomic revision of Dissochaeta is presented, which includes references, a complete list of synonyms, detailed morphological descriptions of the species and an identification key, as well as information on the distribution, habitat and ecology, vernacular names, notes and lists of examined specimens. Fifty four species and two varieties of Dissochaeta are recognised. We designate several lectotypes, propose eleven new combinations and we describe one new species and one new variety.

The Archipini fauna of the Caribbean is revised to include 33 species. Most previously described species occurring in the region are redescribed and figured, with 13 new species: Argyrotaenia brownisp. nov., A. crypticasp. nov. (including A. c. crypticassp. nov. and A. c. praeteritanassp. nov.), A. paradiseisp. nov., A. razowskianasp. nov., Claduncaria rawlinsanasp. nov., Cla. praedictanasp. nov., Cla. tainosp. nov., Clepsis davisisp. nov., Cle. deronisp. nov., Cle. jamesstewartisp. nov., Cle. peroniaesp. nov., Mictocommosis lesleyaesp. nov., and Mictopsichia nyhllindasp. nov. Three new combinations are proposed: Claduncaria mesosignaria (Razowski, 1999), comb. nov. (including Argyrotaenia thamaluncus Razowski, 1999, syn. nov.), Claduncaria minisignaria (Razowski, 1999), comb. nov., and Claduncaria chalarostium (Razowski & Becker, 2000b), comb. nov., stat. nov.Argyrotaenia granpiedrae Razowski & Becker, 2010 is reduced to subspecies rank under Argyrotaenia ceramica Razowski, 1999, resulting in Argyrotaenia ceramica granpiedrae Razowski & Becker, 2010, stat. nov. Four new synonymies are proposed: Clepsis labisclera Razowski & Becker, 2010, syn. nov. as junior synonym of Claduncaria maestrana Razowski & Becker, 2010; Clepsis pinaria Razowski & Becker, 2010, syn. nov. as junior synonym of Clepsis peritana (Clemens, 1860); and Argyrotaenia neibana Razowski, 1999, syn. nov. and A. ochrochroa Razowski, 1999 syn. nov. as junior synonyms of Argyrotaenia amatana (Dyar, 1901). Males of Argyrotaenia felisana Razowski, 1999, A. nuezana Razowski, 1999, and Claduncaria minisignaria (Razowski, 1999), comb. nov. are described for the first time; females of Argyrotaenia jamaicana (Razowski & Becker, 2000a) and Claduncaria ochrochlaena (Razowski, 1999) are described for the first time. The concept of Claduncaria is expanded and its diagnosis is modified to more clearly define its generic boundaries. A unique external sexual coupling mechanism in Claduncaria is discussed. Keys to the genera and species of Caribbean Archipini, distribution maps, a regional checklist, and Neighbor-joining and Maximum Likelihood trees based on COI barcode data are provided. Phylogenetic relationships among Caribbean Archipini are briefly discussed.

ABSTRACT The taxonomic revision of Amorimia (Malpighiaceae) is presented, including typifications, and descriptions for all accepted species. The genus is endemic to Seasonally Dry Tropical Forests and Rainforests of South America, and its species can be distinguished by morphological details of leaves, indumenta, inflorescences, flowers, and fruits. This study includes an identification key for the subgenera and species of Amorimia, illustrations, distribution maps, conservation risk assessments, and comments on ecology, nomenclature, and taxonomy for all species. Additionally, I provide a key to differentiate Amorimia from the remaining genera of the Malpighioid clade.

The genus Dracophyllum Labill. is revised, with a total of 61 species being recognised in four subgenera and two species (Dracophyllum minimum F.Muell. and D. strictum Hook.f.) are listed as incertae sedis. The genus Richea R.Br. is reduced to synonymy under Dracophyllum where it is divided into two new subgenera, namely, Dracophyllum subgenus Cystanthe (R.Br.) S.Venter and D. subgenus Richea (R.Br.) S.Venter. Replacement names published here are Dracophyllum laciniatum S.Venter, D. persistentifolium S.Venter and D. tasmanicum S.Venter, and new combinations published here are Dracophyllum alpinum (Menadue) S.Venter, D. continentis (B.L.Burtt) S.Venter, D. desgrazii (Hombr. ex Decne.) S.Venter, D. gunnii (Hook.f.) S.Venter, D. pandanifolia (Hook.f.) S.Venter, D. procerum (F.Muell.) S.Venter, D. sprengelioides (R.Br.) S.Venter and D. victorianum (Menadue) S.Venter. Nomenclature, descriptions, illustrations, photographs and distribution maps are provided for each species and lectotypes are designated where necessary. A key to the subgenera and keys to species within these are provided.

Previous morphological and molecular studies indicate that the genus Leiothrix is a monophyletic and well supported clade in Eriocaulaceae. A taxonomic revision of the genus for the Flora Neotropica is in progress, but with the Flora do Brasil 2020 project now in its final stages, this synopsis became necessary to present an updated list of accepted species, their synonyms and typifications. Protologues and types of 122 previously published names have been reviewed. The genus now includes 39 species and six varieties, adding up to 42 taxa endemic to Brazil, occurring especially in the Espinhaço Range in Minas Gerais and Bahia States. One species extends from Brazil to other countries of northern South America and one species and one variety are found only in Venezuela. In this paper I propose 34 new synonyms, five new combinations, three changes of status, one neotype and 49 lectotypes.

Croton section Cleodora is a Neotropical section disjunctly distributed in Mexico and Central America, northern and northwestern South America, and eastern Brazil. Eighteen species are recognized as belonging to the section, which is characterized mainly by an arborescent or shrubby habit, presence of clear or reddish latex, leaves with a pair of basilaminar or acropetiolar glands, pistillate flowers sepals with some degree of overlap, and 4-fid or multifid styles united at the base or above, usually forming a crown. We conduct a critical revision of Croton section Cleodora, congruent with the current understanding of its evolutionary history. We provide here an identification key for the two recognized subsections (Croton subsection Sphaerogyni and C. subsection Spruceani) and their species. Descriptions, illustrations, comments about taxonomy, habitat, geographic distribution and phenological information are provided for each species. Six lectotypes are here designated.
