Floristic Treatment

The genus Mucuna comprises approximately 105 tropical and sub-tropical species, with the highest diversity occurring in the Paleotropics. In the Neotropics, 13 new species have been described recently and a number of regional floras have been published. A recent floristic treatment for Colombia has summarized the Mucuna species found in the Neotropics, but since then many new species and new geographical records have been published. A complete taxonomic treatment of all neotropical species and an identification key to all neotropical taxa is currently lacking. The aim of this study is to present a complete taxonomic account of the species of Mucuna occurring in the Neotropics. Descriptions of 25 taxa (24 species and one variety) are included in the treatment, including type specimen details, synonymy, illustrations, distribution maps, and preliminary conservation assessments for each species, together with a species identification key.

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.

SummaryThe genus Thalictrum L. in New Guinea is revised based on morphological evidence. Full descriptions of the genus and the four taxa recognised are given. Two species are recognised: Thalictrum papuanum, widespread across New Guinea, and a new species described here; T. umbraticola, endemic to west New Guinea. Two new varieties are described: Thalictrum papuanum var. acutisegmentum and T. papuanum var. laticarpellum. One new synonym of Thalictrum papuanum var. papuanum is established: T. papuanum var. oranjense.

This paper presents a taxonomic study of genus Vincetoxicum s.str. from southern Asia. Eleven regional endemic species are recognized on the basis of herbarium studies and fieldwork. Three new species are described: V. lenifoliumsp. nov. (endemic to Pakistan), V. stewartianumsp. nov. (endemic to India), and V. subcanescenssp. nov. (endemic to Pakistan, Kashmir and Tibet). Three species names, V. cabulicum, V. glaucum and V. kenouriense, previously treated as synonyms of V. glaucum, V. canescens and V. hirundinaria, respectively, are resurrected. A neotype is designated for the Afghani endemic V. cabulicum. A lectotype is chosen from the syntypes of V. glaucum. We resolve the long-standing taxonomic problems in three species complexes: V. arnottianum, V. luridum, V. sakesarense, and V. stocksii; V. glaucum, V. canescens and V. cabulicum; and V. hirundinaria and V. kenouriense. Geo-taxonomic distinctions of southern Asian taxa are highlighted by excluding from henceforth the long misrecognized western Eurasian taxa V. canescens and V. hirundinaria. Furthermore, a detailed account of the genus including illustrations of whole plants, leaves and corona, distribution maps, a taxonomic key, morphological descriptions, synonymy, notes, and information on phenology, distribution and habitats is provided. Finally, provisional conservation assessments are provided, which indicate that V. cardiostephanum and V. sakesarense are critically endangered.

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.

Scrophularia dianatnejadii Ranjbar & Rahchamani, a new species from Tehran Province in northern Iran, is described and illustrated. It is closely related to S. amplexicaulis Benth. and shares with it some diagnostic morphological characters such as habit, plant indument, phyllotaxy, and corolla shape and color. Both species are placed in Scrophularia L. sect. Mimulopsis Boiss. Macro- and micromorphological characters of the two are examined and compared. Pollen morphology of these species is investigated using SEM. Detailed descriptions, illustrations, distribution maps, and conservation status of both species are provided.

Respective Species

The South American genus Panca Evans, 1955 and its respective species are revised. Previous to this study, the genus included solely its type species, Lerodea subpunctuli Hayward, 1934, until Panca moseri Dolibaina, Carneiro & O. Mielke, 2017 was described recently. However, as a result of a broader morphological study including closely related genera, we here propose that Panca assembles 12 species, most of which inhabit open environments such as the Cerrado biome and the natural grasslands of the Atlantic Forest biome. Eight species formerly included among other genera of Moncina are here combined with Panca: Panca satyr (Evans, 1955) comb. nov., Panca tobiasi (Mielke, 1992) comb. nov., Panca trogon (Evans, 1955) comb. nov., Panca steinhauseri (Dolibaina & A. Warren, 2015) comb. nov., Panca acroleuca (Plötz, 1884) comb. nov., and Panca mirnae (O. Mielke, Dolibaina, Carneiro & A. Warren, 2015) comb. nov. (all formerly in Artines Godman, 1901), Panca paulo (Bell, 1932) comb. nov. (formerly in Eutocus Godman, 1901), and Panca mictra (Evans, 1955) comb. nov. (formerly in Vidius Evans, 1955). Additionally, two new species are described from Brazil: Panca puri Medeiros, O. Mielke & Casagrande sp. nov. (from Pará, Pernambuco, Minas Gerais, Rio de Janeiro and Paraná) and Panca xavante Medeiros, O. Mielke & Dolibaina sp. nov. (from Mato Grosso, Goiás, Distrito Federal and Minas Gerais). A neotype for Apaustus acroleuca Plötz, 1884 is designated. Illustrations of the male and female genitalia and distribution maps are presented for all the species of Panca and an identification key is provided for both sexes.

The genus Paraboea Ridl. (Gesneriaceae) is revised. It is found in Bangladesh, Bhutan, Burma, Cambodia, southern China, India (Assam), Indonesia (Sumatra, Java, Borneo, Sulawesi), Laos, Malaysia (Peninsular and Borneo), Philippines, Thailand and Vietnam, mostly from limestone habitats. Eighty-nine species and five varieties are recognised. Four new species and one new variety are described: Paraboea apiensis Z.R.Xu, Paraboea argentea Z.R.Xu, Paraboea graniticola Z.R.Xu, Paraboea paraprimuloides Z.R.Xu and Paraboea harroviana var. ovata Z.R.Xu. In addition two taxa are highlighted as possible new species but are not described here due to insufficient material. The treatment includes one new combination for a species, Paraboea harroviana (Craib) Z.R.Xu, one new combination for a variety, Paraboea schefferi var. ambigua (C.B.Clarke) Z.R.Xu, one new status for a variety, Paraboea rufescens var. tomentosa (Barnett) Z.R.Xu, and one new name, Paraboea primuloides Z.R.Xu. Fifty-one line drawings are included. A key is presented and all taxa are described. Preliminary conservation assessments are given.
