Three new species are described and illustrated and their conservation status assessed: Elatostema laevicaule W.T. Wang, A.K. Monro & Y.G. Wei, E. androstachyum W.T. Wang, A.K. Monro & Y.G. Wei and E. heterocladum W.T. Wang, A.K. Monro & Y.G. Wei. All are rare endemic species from Guangxi Province, China, and are only known only from their type localities. E. laevicaule is most similar to E. filipes and is assessed as Vulnerable (VU), E. androstachyum is most similar to E. parvum and is assessed as Vulnerable (VU); E. heterocladum is most similar to both E. androstachyum and E. luxiense and is assessed as Vulnerable (VU).

A New Species

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

Angraecoid Orchids

A recent large phylogenetic tree for the angraecoid orchids has shown that the Afrotropical genus Diaphananthe is polyphyletic with a small group of four species sister to Aerangis and Eurychone. These species have diagnostic morphological features different from any other angraecoids, notably an erose to fringed surface of the stipes and a calceiform viscidium. Diaphananthe quintasii, which has been regarded as conspecific with D. rohrii, is reinstated as a valid species and lectotypified, and Diaphananthe alfredii and Rhipidoglossum magnicalcar are put in synonymy under D. quintasii. To accommodate this group of species, along with three new taxa from West and Central Africa, a new genus named Kylicanthe is here described. Four new combinations are thus proposed, and K. bueae is chosen as the type species of the new genus and neotypified. Additionally, K. arcuata, K. cornuata, and K. perezverae are described as new species. An identification key for Kylicanthe and allied genera is presented, as well as one for the seven species in the genus. Notes on ecology and distribution in addition to a preliminary assessment of conservation status following the IUCN Red List are also provided.

Three New Species

The paper provides additions to the known diversity of Begonia in Vietnam and Laos. One species new to science from Lao PDR (B. vivipara) and three new species from Vietnam (B. aspersa, B. gracilifolia, B. maculifolia) are described. Three species (B. rotundilimba, B. versicolor, B. wenshanensis) are reported as new records for the flora of Vietnam. For each species, the information on ecology, phenology, estimated conservation status and distribution is presented, as well as the relevant taxonomic notes and analytical photographic illustrations.

A New Species

Pycreus rubidomontanus is described as a new species. It is relatively widespread in tropical West Africa where it had been confused up to present with P. atrorubidus, a very rare endemic species from Zambia in south-central Africa that probably is known only from the type gathering. Differences between these and other similar species are discussed and the new species is copiously illustrated.

We describe here Begonia medeiroii, a narrow endemic species from the Atlantic Rainforest. The conservation status of this species was assessed as critically endangered according to IUCN criteria. This species resembles to B. catharinensis and B. hirtella in some characteristics, differing among other features due the presence of adventitious vegetative buds on the adaxial surface of the leaves.

Three new Brazilian species of Aulonemia, a Neotropical woody bamboo genus, are described and illustrated: Aulonemia cincta, with its distinctive corky girdles; Aulonemia prolifera, characterized, among other Brazilian congeners, by its fimbriate leaf sheaths; and Aulonemia soderstromii, with its conspicuous cluster of spreading fimbriae. These new species all propagate by amphipodial rhizomes, an unusual feature shared with the Brazilian species A. aristulata, with which they are morphologically compared. Comments about habitat, distribution, phenology, and conservation status for each species are provided, as well as photographs taken in the wild.

We describe and illustrate three new species of Paepalanthus (Eriocaulaceae: Paepalanthoideae) from the Espinhaço Range: P. argyrotrychus, P. farinaceus and P. velutiphyllus, all endemic to Serra do Ambrósio, a mountain disjunct from the Espinhaço Range in the municipality of Rio Vermelho, Minas Gerais, Brazil. These species belong to Paepalanthus ser. Paepalanthus (=Paepalanthus [unranked] Variabiles). We provide detailed descriptions and illustrations for each taxon, as well as comments on habitat, distribution, morphology, conservation and their affinities to the most morphologically similar species.

16S Sequence

Three new species of the genus Amynthas are described from Guangxi Province, China. They are named A. dissimilis sp. nov., A. anteporus sp. nov. and A. marsupiformis sp. nov. All of them have two pairs of spermathecal pores in 6/7–7/8, and belong to the tokioensis-group. Their morphological characteristics are compared to similar species in tokioensis-group from China and other Asian countries. In addition, the mitochondrial COI and 12S-tRNA-Val-16S sequence of three new species were determined, then pairwise distances between species were calculated. Both morphological and molecular evidences could easily distinguish the new species from earthworms previously reported in the tokioensis-group.
