A New Species

Argostemma separatum, a new species with free stamens in star-shaped corolla from Mt. Halcon Oriental Mindoro, Philippines is here described and compared with Argostemma diversifolium, the only species of the genus with this type of flower. This species is distinct from A. diversifolium by its indumentum on stem, leaf blades and calyx, smaller leaf blades, fewer flowered inflorescences, shape of stipule and calyx, red tips on corolla lobes, and color of anthers. Based on the recent IUCN categories, the conservation status of A. separatum is Data Deficient (DD) since it was only collected at the type locality.

A New Species

Chayamaritia vietnamensis, a new species from Son La Province, northern Vietnam, is described and illustrated. The phylogenetic study revealed that the new species is most closely related to C. banksiae and C. smitinandii. The morphological comparison suggests it as the third new species of Chayamaritia and distinguished from C. banksiae and C. smitinandii by a combination of morphological characters of leaf blades, bracts, calyx and corolla, especially its peltate leaf blades. This species is provisionally assessed as endangered (EN B1ab(iii), B2ab(iii)) using IUCN Categories and Criteria. Information on ecology, phenology and an identification key for the known Chayamaritia species are also provided.

We describe a new species of the Rhacophorus genus, which differs from all species known in Asia by the combination of characters. It strongly differs also from small and middle-sized species of Rhacophorus sensu lato: Rhacophorus calcaneus Smith, 1924, Leptomantis cyanopunctatus (Manthey et Steiof, 1998), Rhacophorus hoabinhensis Nguyen, Pham, Nguyen, Ninh et Ziegler, 2017, Rhacophorus hoanglienensis Orlov, Lathrop, Murphy et Ho, 2001, Zhangixalus jarujini (Matsui et Panha, 2006), Rhacophorus laoshan Mo, Jiang, Xie et Ohler, 2008, Rhacophorus pardalis Günther, 1858, Rhacophorus rhodopus Liu et Hu, 1960, Rhacophorus robertingeri Orlov, Poyarkov, Vassilieva, Ananjeva, Nguyen, Sang, and Geissler, 2012, Leptomantis robinsonii (Boulenger, 1903), Rhacophorus spelaeus Orlov, Gnophanxay, Phimminith, and Phomphoumy, 2010, Rhacophorus translineatus Wu, 1977, Rhacophorus turpes Smith, 1940, Rhacophorus vampyrus Rowley, Le, Thi, Stuart et Hoang, 2010, Rhacophorus viridimaculatus Ostroshabov, Orlov et Nguyen, 2013 by having brown color with two green dorsolateral stripes starting at the groin level and connecting through the distal part of eyelid with green triangle on the head, slender body and head, lower ratio HW/HL 0.86, lower HW/SVL 0.28 and lower ratio HL/SVL 0.32.

A New Species

Peliosanthes longiracemosa, a new species from limestone areas of northern Vietnam, is described and illustrated. It is most similar to P. macrostegia in having a distally incurved staminal corona and a distinct pyramidal style, but clearly distinguishable chiefly by the broader leaf blades with more longitudinal veins and closer transverse veinlets, relatively longer, more slender raceme, more numerous widely expanded flowers with recurved perianth segments, and more incrassate, depressed globose staminal corona. Information on the habitat and phenology as well as notes on the taxonomic relationships with other congeners is also provided.

Abstract - Populations of herbaceous periwinkle, Vinca herbacea Waldst. et Kit., were found on April 2007 on Bansko Hill (Baranja, Croatia), which lies on the south-western edge of the range of this Pontic-Pannonian species. Since V. herbacea was included neither in the handbooks for plant identification nor in the current Croatian Flora Database, a new key for the determination of Vinca L. species of Croatia is presented herein. The herbaceous periwinkle should be treated as a critically endangered (CR) species in Croatia, considering the low number of individuals and the small extent of its occurrence in extremely rare habitats at the margin of its distribution. New recordings of some very rare or »data deficient « (DD) taxa of Croatia are also presented here: Scorzonera hispanica L. and Inula germanica L.

A New Species

A peltate-leaved species of Begonia was recently collected from a limestone hill in central Guangxi, China. Based on a careful study of literature, herbarium material, and plants both in the wild and in cultivation reveals that it is a new species of Begonia sect. Coelocentrum, which we hereby describe as B. ufoides. In addition to a full taxonomic account, color plates and line drawings are provided to aid in identification. Begonia ufoides may be confused with B. umbraculifolia Y. Wan & B.N. Chang in southwestern Guangxi and B. phuthoensis H.Q. Nguyen in northern Vietnam, both of which are peltate-leaved calciphilous species in sect. Coelocentrum, but the new species  is clearly distinguishable in many morphological characters. A table comparing salient features of the three species is presented.

A New Species

The genus Aspidistra Ker Gawler (1822: 628) is represented in tropical and subtropical SE Asia by more than 160 species. It has the highest diversity in southern China and northern Vietnam (Tillich 2005, 2014, Tillich & Averyanov 2012, Vislobokov et al. 2013). In Vietnam, more than 50 species are known: many species have been discovered from the limestone regions in North Vietnam, while about 21 species are found from sandstone forests in Central and South Vietnam (Gagnepain 1934, Bogner & Arnautov 2004, Bräuchler & Ngoc 2005, Averyanov & Tillich 2012, 2013, 2016a, 2016b, Averyanov et al. 2016, Tillich 2005, 2014, Tillich & Averyanov 2008, Tillich et al. 2007, Leong-Škorničková et al. 2014, Vislobokov 2015, Vislobokov et al. 2013, 2014b, 2014c, 2016a, 2016b, Lý & Tillich 2016). During extensive floristic surveys in Central Vietnam in 2016, several interesting specimens of Aspidistra were collected by the first author. The critical examination of these specimens and study of literature for Aspidistra in Vietnam and neighbouring countries allowed to evidence several new taxa, two of which have been recently described: A. averyanovii Lý & Tillich (2016: 54) and A. parviflora Lý & Tillich (2016: 56). In the present paper, we describe a further new species from Cà Đam mountains, Quảng Ngãi Province, namely Aspidistra cadamensis.

A New Species

A new species of Quercus (Fagaceae), Q. ngochoaensis, from Ba Vi National Park, Ha Noi, northern Vietnam is described and illustrated. This species is morphologically similar to Q. glauca in having glabrous twigs, cuneate leaf base, two or three fruits per infructescence, almost entire margin of lamellate rings on cupule except the lowest three rings, slightly convex scar at the base of a nut. However, it differs from Q. glauca in having smaller leaves, cup-shaped cupule enclosing 1/2–2/3 of the nut, 7–8 lamellate rings on cupule, and subglobose nut. In addition to the description, DNA barcodes of the two partial plastid regions of matK, rbcL and the nuclear region of ITS of the new species are provided.
