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.

The Indo-Australian crowned weevil genus Asytesta Pascoe, 1865 is revised. Forty-one species are recognized, including18 that are new: A. alexandriae, A. alexriedeli, A. allisoni, A. biakana, A. cheesmanae, A. concolora, A. emarginata, A.fayae, A. frontalis, A. gressitti, A. julieae, A. marginalis, A. morobeana, A. sedlaceki, A. thompsoni, A. tuberculata, A.vivienae, and A. woodlarkiana, new species. One subspecies, A. lugubris bidentata Voss is elevated to species status, A.bidentata Voss, new status. Four species are newly synonymized: A. circulifera Lea, 1928 = A. rata Heller, 1910, A.definita Faust, 1898 = A. humeralis Pascoe, 1865, A. granulifera Lea, 1928 = A. aucta Faust, 1898, and A. setipes Lea,1928 = A. lugubris Heller, 1895 new synonyms. Six new species groups are proposed. Lectotypes are designated for 18species. Two species are transferred from Asytesta to other genera: A. maura Pascoe to Microporopterus Lea and A.ypsilon Heller to Meroleptus Faust, new combinations. A checklist and key for all crowned weevil genera, key to speciesgroups and species of Asytesta, adult habitus illustrations, distribution maps, and line drawings of diagnostic charactersare provided.A phylogeny for the genus based on 82 adult morphological characters (187 states) for 41 ingroup taxa is alsopresented. All genera and species of the crowned weevil group as redefined here (including Cyamomistus Heller,Eudyasmus Pascoe, Glochinorhinus Waterhouse, Nothotragopus Zimmerman, Panopides Pascoe, and Zygara Pascoe),were included in the analysis to test the monophyly of Asytesta. Monophyly of Asytesta was supported only with thesynonymy of the monotypic genus Zygara. Accordingly, Zygara is a new junior synonym of Asytesta and Zygara doriae (Kirsch) is returned to its original combination with Asytesta; A. doriae Kirsch resurrected status.

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. Keys to the taxa and distribution maps, as well as preliminary conservation assessments, are provided.

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.

The Morelloid clade, also known as the black nightshades or “Maurella” (Morella), is one of the 10 major clades withinSolanumL. The pantropical clade consists of 75 currently recognised non-spiny herbaceous and suffrutescent species with simple or branched hairs with or without glandular tips, with a centre of distribution in the tropical Andes. A secondary centre of diversity is found in Africa, where a set of mainly polyploid taxa occur. A yet smaller set of species is found in Australasia and Europe, includingSolanumnigrumL., the type of the genusSolanum. Due to the large number of published synonyms, combined with complex morphological variation, our understanding of species limits and diversity in the Morelloid clade has remained poor despite detailed morphological studies carried out in conjunction with breeding experiments. Here we provide the first taxonomic overview since the 19thcentury of the entire group in the Old World, including Africa, Asia, Australia, Europe and islands of the Pacific. Complete synonymy, morphological descriptions, distribution maps and common names and uses are provided for all 19 species occurring outside the Americas (i.e. Africa, Asia, Australia, Europe and islands of the Pacific). We treat 12 species native to the Old World, as well as 7 taxa that are putatively introduced and/or invasive in the region. The current knowledge of the origin of the polyploid species is summarised. A key to all of the species occurring in the Old World is provided, together with line drawings and colour figures to aid identification both in herbaria and in the field. Preliminary conservation assessments are provided for all species.
