The present work is an effort to untangle the taxonomy of Phlogacanthus pulcherrimus, a poorly known species reported here for the first time for the flora of Vietnam. Fresh specimens of this species were collected from three localities in Southern Vietnam. They provided new insights to its appearance and morphology. Phlogacanthus pulcherrimus can be distinguished from the morphologically close P. geoffrayi and P. turgidus by oblanceolate-obovate, light to dark purple flower-subtending bracts, oblanceolate bracteoles, and staminodes 1 mm long. The corolla of the Vietnamese specimens of P. pulcherrimus is uniformly dark purple outside. A detailed description, photographs, and information on habitat, ecology and distribution of P. pulcherrimus are provided. Typification of this name is performed, and a specimen at K (K000885620) is designated as a lectotype.

A New Species

The new species, Bulbophyllum manhdatii (B. sect. Brachyantha) discovered in Da Lat Plateau, Lam Dong Province (southern Vietnam) is described here. This new species is close to B. pumilio but clearly differs in densely crowded pseudobulbs and their shape, shorter inflorescence, lateral sepals forming a narrow acute tube slightly flattened at the base, lip without median keel, and longer stelidia. In addition, a new national record, B. seidenfadenii, from the same section is also reported from the first time from North Vietnam.

The genus Euepedanus of the family Epedanidae is recorded from Vietnam for the first time. Euepedanus vietnamicus sp. nov. (males and females) is diagnosed, figured and described. The main characteristics that distinguish this species from other species Euepedanus are quite large body sizes, structure of the distal segment of the chelicerae, armament of palps and on the dorsal surface of body with a pattern resembling the Latin letter X. The only known locality of the new E. vietnamicus sp. nov. in southern Vietnam, is mapped.

Ho et al. proposed to exclude Stenogyne section from the genus Gentiana and classifying it as a distinct genus (Metagentiana). Fourteen species of this genus have been recorded and distributed in China, Myanmar and Thailand. This is the first time there has been a confirmed genus Metagentiana distributed in Vietnam. This genus has two species: Metagentiana rhodantha and Metagentiana primuliflora, which are proposed in Vietnam. Particularly, Metagentiana rhodantha, which had only been known from China, was reported in Vietnam. A detailed description along with their distribution, habitat, ecology, illustrations, and photos has been provided to aid species identification. The key to identify all taxa of the genus has been constructed

Selection Of

The Psychedelic Rock Gecko,Cnemaspispsychedelica, was described in 2010 and certainly belongs to the most spectacular gecko discoveries worldwide. The species is endemic to two small offshore islands in Rach Gia Bay. Its striking colour pattern makes the species highly attractive for the international pet market. The existentCnemaspispopulation is negatively affected by habitat degradation and predation by introduced macaques. We herein provide the first characterisation of microhabitat selection of this species, including seasonal variation on Hon Khoai and Hon Tuong islands, Ca Mau Province, Vietnam. We found that characteristics of the selected microhabitat, such as substrate type, temperature and canopy cover slightly differed between the wet and dry seasons. We also demonstrated age-related differences in the selection of perch heights. Communal nesting was, for the first time, reported forC.psychedelica, as well as natural predation by a snake species (Lycodoncapucinus). In addition, we documented ongoing habitat destruction on Hon Khoai Island and recorded illegal trade of live Psychedelic Rock Geckos for the first time on local pet markets in both northern and southern Vietnam. Our findings highlight the need for improved conservation measures in order to reduce anthropogenic impacts on wild populations ofC.psychedelica.

The Relationship

Elatostema (Urticaceae) comprises several hundred herbaceous species distributed in tropical and subtropical Africa, Asia, Australia and Oceania. The greatest species richness occurs on limestone karst in Southeast Asia. Taxonomic revisions of Elatostema are largely out of date and contradict each other with respect to the delimitation of Elatostema and Pellionia. Most herbaria in SE Asia and worldwide contain significant amounts of unidentified material. As part of a broader revision of Elatostema in SE Asia, we present an updated checklist for Vietnam based on field visits, a review of specimens in herbaria worldwide, a review of type material and nomenclature. We recognize 77 taxa (75 species and two infraspecific taxa) of Elatostema in Vietnam, 23 of which were previously ascribed to Pellionia. Nineteen of these are new records for the country, i.e., E. attenuatoides, E. austrosinense, E. backeri, E. brunneinerve, E. crassiusculum, E. crenatum, E. fengshanense, E. glochidioides, E. malacotrichum, E. nanchuanense, E. oblongifolium, E. obtusum, E. oppositum, E. pergameneum, E. prunifolium, E. pseudolongipes, E. pycnodontum, E. salvinioides and E. xichouense. We place E. baviensis in synonymy of E. platyphyllum, E. colaniae in synonymy of E. myrtillus, P. macroceras in synonymy of E. hookerianum, and P. tetramera in synonymy of E. dissectum for the first time. Fourteen taxa (18% of all the recognized taxa) are endemic to Vietnam, which makes Elatostema one of the richest genera for endemic species in this country; this level of endemism is comparable to levels observed in Orchidaceae. Our checklist suggests that the highest diversity and endemism of Elatostema occurs in northern Vietnam, and that there is the greatest floristic similarity of northern Vietnam to SW China. The relationship among floristic regions is also investigated. We could find no records of Elatostema for 33 out of 63 provincial units of Vietnam, including all the southernmost provinces. We propose that further studies on the diversity of Elatostema in central and southern Vietnam are severely needed.

Astragalus autranii (Fabaceae) placed by Sytin & Podlech in a section of its own (A. sect. Baldaccia) was described from a single specimen in the Barbey-Boissier Herbarium at Geneva. Our observations show that its placement in A. sect. Hololeuce would also be appropriate. The species was first collected by Baldacci in 1892 on Mt Tomor in south central Albania and rediscovered by Markgraf at the locus classicus in June 1928. A complete and amended description of the species is here provided as corolla features were not available in the type material and the flower colour was incorrectly described by Markgraf. Information on habitat, ecology and threat status are also detailed for the first time. Mt Tomor is designated as a protected National Park; however, some of the Astragalus populations may be affected by future road construction.
