Tristagma is a South American genus distributed in Argentina and Chile. Species circumscription in Tristagma has been a source of confusion for various reasons; e.g., generic concepts, nomenclatural inconsistencies, and doubtful species. As a first step towards a revision of Tristagma, the nomenclatural history is reviewed. Following an extensive review of specimens in various American and European herbaria, a generic description and a list of names and their types are here provided. Thirteen names are lectotypified, seven are synonymized, three holotypes are identified for the first time, one neotype is designated, a new combination is made, and 12 species are recognized: T. ameghinoi, T. anemophilum, T. berteroi, T. bivalve, T. circinatum, T. gracile, T. graminifolium, T. nivale, T. patagonicum, T. poeppigianum, T. porrifolium, and T. violaceum. A new record of the flora of Chile: T. circinatum is also reported. Additionally, five doubtful species are mentioned and three are excluded from Tristagma. Another five species names referred in the literature to Tristagma have already been transferred to other genera. We also provide conservation assessments, distribution maps and an identification key to species.

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.

Homollea Arènes (Rubiaceae, subfamily Ixoroideae, tribe Pavetteae) is a genus of shrubs and small trees endemic to western and northern Madagascar. The genus comprises five species occurring in dry deciduous forest, often in limestone areas. The five species are narrow endemics and their conservation status is either Endangered (4 species) or Critically Endangered (1 species). Homollea is characterized by few-flowered, pseudo-axillary, pedunculate inflorescences, well-developed calyces with the lobes much longer than the tube, laterally flattened seeds with a shallow, elongated to linear hilum and entire endosperm, ovules arising from the upper margin of the placenta, and, pollen grains with supratectal elements in the shape of microgemmae. Until now, three species were known and their descriptions are amended. Two further species, H. furtiva De Block sp. nov. and H. septentrionalis De Block sp. nov., are described as new for science. The five species are dealt with in detail: descriptions, distribution maps, conservation assessments, illustrations, lists of exsiccatae and an identification key are given.

This paper provides a taxonomic revision of the Neotropical ant genus Hylomyrma Forel (1912) (Myrmicinae: Pogonomyrmecini). Morphological traits combined with geographical data and natural history information led to the recognition of 30 species, fourteen of them described here as new: Hylomyrma adelae sp. n., Hylomyrma dandarae sp. n., Hylomyrma jeronimae sp. n., Hylomyrma lispectorae sp. n., Hylomyrma lopesi sp. n., Hylomyrma macielae sp. n., Hylomyrma margaridae sp. n., Hylomyrma mariae sp. n., Hylomyrma marielleae sp. n., Hylomyrma mitiae sp. n., Hylomyrma peetersi sp. n., Hylomyrma primavesi sp. n., Hylomyrma virginiae sp. n. and Hylomyrma wachiperi sp. n. Lectotypes for H. speciosa (junior synonym of H. balzani) and H. reitteri are here designated from syntypes to improve nomenclatural stability. Except for the three species most recently described (H. montana, H. plumosa, and H. villemantae), the external morphology of workers is described or redescribed, as well as for the known males and queens, most described here for the first time. Of the 30 recognized species herein, 11 present intercastes; at least three of them present female specimens with queen-like traits that may be understood as ergatoids. An updated identification key for Hylomyrma workers is provided, as well as high resolution photographs of all known sexes and castes, species distribution maps, and a summary of what is known from the biology of 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 is the first botanical contribution from the C.S.I.R.O. Northern Australia Regional Survey. Revised accounts of 50 species with discussions on taxonomy, distribution, and typification of names are the result of a partial revision of the genus Eucalyptus as represented in the northern part of Australia; keys to two groups particularly studied are given. All the 42 species known from the northern part of the Northern Territory are treated, with three keys to their identification; the first of these is based on characters observable in the field, the second on hand specimens with buds and flowers, and the third on hand specimens with fruits only. New criteria for the discrimination of species have been used, and some examples of their application are shown graphically; these include the number of lateral veins in the leaf, the ratio of its length to its breadth, and (to some extent) the exact distance of the intramarginal vein from the margin and the shape of the free part of the calyx-tube of the flower. The juvenile stages, flowers, fruits, and seeds are described for the first time for some species. Types of all names, with the herbaria in which they are to be found, are cited, with reference to published figures, some of which appear for the first time in this paper. Several lectotypes are designated, and the guiding principles adopted for their selection are described. Citations of specimens are restricted to those collected in 1946-9 on the Northern Australia Regional Survey, to types, new records, and some critical collections. Distribution maps of 51 species are based on all specimens examined. Plates from photographs illustrate the characteristic habit of some species, the deciduous nature of some, a few characteristic barks, various type specimens and some other specimens cited in taxonomic discussions. The status of about 160 names was investigated. Among others, E. clavigera A. Cunn. ex Schau., E. polycarpa F. Muell., E. terminalis F. Muell., E. foelscheana F. Muell., and E. racernosa Cav. are shown to have been originally applied to species different from those currently passing under these names. Many names are treated as synonyms on taxonomic grounds, 24 of them for the first time. All nomenclatural changes are summarized in two tables. One new species, E. porrecta S. T. Blake, and one new combination, E. gilbertensis (Maiden & Blakely) S. T. Blake, are proposed. The following species are new records for the areas mentioned: E. Izerbertiana and E. cliftoniana (Northern Territory) ; E. aspera and E. ferruginea (Queensland) ; E. bigalerita and E. patellaris (Western Australia) ; and E. dichromophloia (South Australia). In an appendix, the graphical methods and distribution maps are discussed and some remarks made on the phylogeny and history of distribution of the genus.
