Premna grandipaniculata (Lamiaceae, Premnoideae), a remarkable new species from north Myanmar.

ABSTRACT: A remarkable new Premna species from Myanmar, P. grandipaniculata Y.H.Tan & Bo Li (Lamiaceae), is here described and illustrated. It differs from all known congeneric taxa by having huge complicated panicles which have tertiary branches formed by spike-like thyrses. In Premna, such a spike-like thyrse is found in P. bracteata and P. interrupta, but those species can be easily distinguished from P. grandipaniculata by their habit, indumentum, leaf size and inflorescence structure.

Premna bhamoensis (Lamiaceae, Premnoideae), a new species from Kachin State, northeastern Myanmar.

Project description:In the present study, we describe and illustrate a new species, Premna bhamoensis Y. T. Tan & B. Li (Lamiaceae), from Myanmar. In the 1980s, this species was transplanted from Bhamo County in northeastern Myanmar to the Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences. The species shows striking morphological similarity to P. menglaensis B. Li, and thus, has been misidentified as the latter for a long period of time. However, morphological comparison revealed that P. bhamoensis is distinct from P. menglaensis in many aspects. Moreover, literature survey and specimen examinations also indicated that P. bhamoensis is undoubtedly different from all seven known congenetic species recorded from Kachin State, Myanmar, and a key for their identification has been provided in this paper.

Premna vietnamensis (Lamiaceae, Premnoideae), a distinct new species from the Central Highlands of Vietnam.

Project description:Premna vietnamensis, a distinct new species which is endemic to Gia Lai Province in Central Highlands of Vietnam, is described and illustrated. It is characterized by its calyx tube bearing a semi-globose fleshy appendage, which has not been reported before from all known congeneric taxa, as well as from the Lamiaceae. A phylogenetic analysis of the whole Lamiaceae based on a sampling including representatives from all 12 currently recognized subfamilies confirmed the placement of this new species within Premna of the Premnoideae. Morphologically and geographically, P. vietnamensis is most similar to P. stenobotrys, but differs significantly in many aspects.

Aristolochia sinoburmanica (Aristolochiaceae), a new species from north Myanmar.

Project description:Aristolochia sinoburmanica Y.H.Tan & B.Yang, a new species of Aristolochiaceae from Putao, Kachin State, Myanmar, is described and illustrated. According to morphology (strongly curved perianth, 3-lobed limb, as well as 3-lobed gynostemium, anthers 6, adnate in 3 pairs to the base of gynostemium, opposite to the lobes), the species belongs to Aristolochia subgenus Siphisia. It is morphologically similar to A. faviogonzalezii, A. hainanensis, A. tonkinensis, A. saccata and A. xuanlienensis. The major differences between them are outlined and discussed. A detailed description, along with line drawings, photographs, habitat, distribution and conservation status, as well as a comparison to morphologically similar species, are also provided.

A new remarkable species of Alloscorpiops Vachon, 1980 from Myanmar (Burma) (Scorpiones, Scorpiopidae).

Project description:Among the genera of the family Scorpiopidae Kraepelin, 1905 Alloscorpiops remains yet rather discrete. New species were added to this genus only recently, increasing its number from two to six. Therefore, species of Alloscorpiops can be considered rare and uncommonly collected. One particular new species, Alloscorpiops viktoriaesp. n., is described based on two females and one pre-adult male collected from the northern part of central Myanmar (Burma). The new species presents most features exhibited by scorpions of the genus Alloscorpiops, but it is characterised by a moderate to small size, very strongly marked granulation, and a particular trichobothrial pattern. Aspects of the ecology and distribution of the new species are discussed and compared with those of other species of genus Alloscorpiops.

Paraphlomisyingdeensis (Lamiaceae), a new species from Guangdong (China).

Project description:Paraphlomisyingdeensis (Lamiaceae), a new species from the limestone area in northern Guangdong Province, China, is described and illustrated. Phylogenetic analyses, based on two nuclear DNA regions (ITS and ETS) and three plastid DNA regions (rpl32-trnL, rps16 and trnL-trnF), suggest that P.yingdeensis represents a distinct species in Paraphlomis. Morphologically, P.yingdeensis is similar to P.foliatasubsp.montigena and P.nana, but can be distinguished from the former by its densely villous lamina and calyx, not decurrent base of lamina and bristle-like-acuminate apex of calyx teeth, and distinguished from the latter by its significantly taller plant (15-20 cm vs. 1-5 cm) and larger lamina (6.2-16.5 × 4-11.5 vs. 2-7 × 1.5-4 cm), densely villous stem, lamina and calyx and yellow corolla.

New Cladosporium Species from Normal and Galled Flowers of Lamiaceae.

Project description:A series of isolates of Cladosporium spp. were recovered in the course of a cooperative study on galls formed by midges of the genus Asphondylia (Diptera, Cecidomyidae) on several species of Lamiaceae. The finding of these fungi in both normal and galled flowers was taken as an indication that they do not have a definite relationship with the midges. Moreover, identification based on DNA sequencing showed that these isolates are taxonomically heterogeneous and belong to several species which are classified in two different species complexes. Two new species, Cladosporium polonicum and Cladosporium neapolitanum, were characterized within the Cladosporium cladosporioides species complex based on strains from Poland and Italy, respectively. Evidence concerning the possible existence of additional taxa within the collective species C. cladosporioides and C. pseudocladosporioides is discussed.

Gastrodia kachinensis (Orchidaceae), a new species from Myanmar.

Project description:Gastrodia kachinensis, a new species of Orchidaceae, is described and illustrated from Putao, Kachin State, Myanmar. It is morphologically similar to G. gracilis, presumably its nearest relative, but can be easily distinguished from the latter by having perianth tube with punctate outer surface, verrucose outer surface of sepal lobe, orbicular petals, ovate-elliptic lip with truncate apex and auriculate-clawed base, glabrous lip apex with a pair of twin protuberance-like lamellae and column with a pair of blade-like lateral wings and acute stelidia at apex. Identification key and colour photographs are provided. A preliminary risk-of-extinction assessment, according to the IUCN Red List Categories and Criteria, is given for the new species.

Two new species of Gingers (Zingiberaceae) from Myanmar.

Project description:Two new species of gingers (Zingiberaceae), Globba sherwoodiana W.J. Kress & V. Gowda sp. nov., and Curcuma arracanensis W.J. Kress & V. Gowda sp. nov., from Myanmar are described. The new species of Globba is currently only known in cultivation and is commonly grown and sold in markets in Myanmar. In contrast Curcuma arracanensis has been collected from a single restricted region in the cloud forests of the Rakhine Yoma above the Bay of Bengal in western Myanmar. Three-locus DNA barcodes were generated as aids for the identification of the two new species.
