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.

Taxonomic revisions are the most reliable pathway in unfolding new species to the world. During such a revision of the genus Lagenandra in Sri Lankan, we came across two new species: Lagenandra kalugalensis and Lagenandra srilankensis from the Wet Zone of Sri Lanka. The two new species were studied in detail and compared with the morphology of the other species described in the genus, and based on field collected data conservation assessments were performed. A detailed description for the two new species and an updated taxonomic key to the Sri Lankan Lagenandra is presented here for easy identification. Recognizing two new endemic members enhances the number of Sri Lankan species of Lagenandra to eleven and global to nineteen. According to the IUCN red data category guidelines, L. kalugalensis qualifies for Critically Endangered category under Criterion B1ab (ii,iii,v) + B2ab (ii,iii,v) while L. srilankensis qualifies for Critically Endangered category under B1ab (iii, iv) + C2 (a) (i, ii). Hence, immediate conservation measures are imperative.

Two apparently narrow-endemic species of Eugenia are described from the Cabo Frio Center of Plant Diversity in the state of Rio de Janeiro, Brazil. Both present a limited distribution restricted to coastal areas north of Rio de Janeiro. The new species are described and compared with closely related species.  Illustrations, distribution maps and conservation status assessments are also provided. Eugenia gastropogena and Eugenia farneyi are presumably closely related to Eugenia pyriformis and Eugenia malacantha. Eugenia gastropogena can be recognized by its leaves with arched secondary veins not forming a clear marginal vein, subcordate to obtuse leaf bases, petioles 2.1–4.8 mm long, buds 3.5–4 mm long and 2 ovules per locule. E. farneyi can be recognized by having leaves with straight secondary veins that form a single marginal vein running 0.7–1.5 mm from the margin, cuneate leaf bases, petioles 4–6.4 mm long, buds 6.2–8.4 mm long, and 10–12 ovules per locule.

Adenocalymma, with approximately 75 species, is one of the largest genera from tribe Bignonieae (Bignoniaceae). The genus mostly includes yellow-flowered lianas and shrubs that are conspicuous components of the dry and wet Neotropical forests. As part of an ongoing taxonomic and phylogenetic study of this group, we found unusual materials that do not match any of the currently recognized taxa. These materials formed the basis of two new species described here, which are endemic from the Brazilian Atlantic forest: Adenocalymma lineare, and Adenocalymma apetiolatum. Adenocalymma lineare resembles Adenocalymma nervosum on the linear leaflets, but differs in the habit, prophyll morphology, leaflet venation, floral bracts, bracteole morphology and dimensions, corolla color and morphology, anther and stigma position. While Adenocalymma apetiolatum closely resembles Adenocalymma sessile and Adenocalymma subsessilifolium on the sessile leaf insertion and shrubby habit, it differs from both species by the corolla color, indument type and color. Apart from that, Adenocalymma apetiolatum differs from the former by the prophyll morphology, floral bract and bracteole morphology, and the latter by the corolla morphology. These two new taxa are illustrated, and distribution maps are provided here. Notes on the taxonomy, geographic distribution, habitat, and conservation status are also included.

Two new species of Myrcia s.l. from the Atlantic Forest of southeastern Brazil are here described and illustrated. Myrcia longisepala and M. rogersiana share morphological features which place them in the Gomidesia clade. The species are recorded for lowland and submontane forests in the Atlantic Forest. Myrcia longisepala is morphologically related to M. congestiflora, but differs by its smaller leaves, fewer secondary leaf veins, smaller petioles and fruits. Myrcia rogersiana is morphologically related to M. springiana, but differs by its reduced inflorescence main axis and flowers clustered at the apex of the inflorescence. Distribution maps and conservation assessments based on IUCN criteria are also given.

Species Descriptions

Pombalia Vand. (Violaceae) is represented in the Cerrado by a well-supported monophyletic group of species known as the Pombalia lanata complex, characterised by some unique vegetative and reproductive features within the genus. This group includes six species – Pombalia cristalina, P. insignis, P. lanata, P. poaya, P. strigoides and P. velutina – the first two of which are new to science. Pombalia lanata shows the widest geographical distribution throughout the Central Brazilian Plateau and the Espinhaço Range in Minas Gerais state, with a disjunction in Misiones Province, Argentina. Because most species in this group are narrow endemics, we evaluated the conservation status of all taxa. An identification key for the species, descriptions, illustrations, maps of geographical distribution and nomenclatural notes are also provided.

Inga (Fabaceae, mimosoid clade) is an important genus in the Atlantic Forest of Brazil where there are 44 species, 60% of which are endemic. In this work, we describe two new species of Inga (I. teresensis and I. tripa) from the Atlantic Forest and provide identification keys to the species of sections Vulpinae and Leptinga in the biome. Illustrations and comments about the geographic distribution, conservation status, phenology, etymology, and taxonomy of the new species are also included. Inga teresensis is only known from the state of Espírito Santo and is categorized as Critically Endangered (CR). Inga tripa occurs in coastal areas of the states of Bahia, Paraíba, Pernambuco, and Sergipe and is categorized as Learn Concern (LC).

Two new species of Callulina are described from the Nguru Mountains, one from the main Nguru South block (C. hanseni sp. nov.) and one from the outlying mountain fragment of the Nguru in Kanga Forest Reserve (C. kanga sp. nov.). The species are diagnosed based on a combination of morphological, acoustic and molecular data. An updated key to the species of all the known Callulina is provided. The conservation status of the two species is examined and, based on highly restricted distributions and ongoing threat to their Nguru Mountain habitats, we recommend a Critically Endangered categorisation. Additional species of Callulina remain to be described from the Nguru Mountains, underlying the extraordinary diversity of the genus in this area.

Raphia (Arecaceae, Calamoideae) is the most diverse genus of African palms with around 20 species. Two new species from Cameroon and Gabon, Raphiagabonica Mogue, Sonké & Couvreur, sp. nov. and Raphiazamiana Mogue, Sonké & Couvreur, sp. nov. are described and illustrated. Their affinities are discussed and the conservation status of each species is assessed. For both species, distribution maps are provided. Raphiagabonica is restricted to two small populations from central Gabon, where it occurs on hillsides on tierra firme soil, and close to small streams. Its preliminary IUCN status is Endangered, being amongst the five most threatened palm species in Africa. Raphiagabonica potentially belongs to the moniliform section. Raphiazamiana is largely distributed from south Cameroon to south Gabon and is very common. It is also a multi-used palm, from which wine, grubs and construction material are extracted and sold. It generally occurs in large stands in a wide range of ecosystems such as swamps, coastal forests on partially inundated sandy soils and inundated savannahs. Its large stature, hard to access habitat (swamps) and abundant presence might have discouraged botanists to collect it until now. Raphiazamiana belongs to the taxonomically complex raphiate section.
