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.

The genus Aspidistra Ker Gawler (1822: 628) contains more than 160 species in tropical and subtropical SE-Asia, with the centre of species diversity in southern China and adjacent northern Vietnam (Tillich 2005, 2014, Tillich & Averyanov 2012, Vislobokov et al. 2013). In Vietnam, the genus has more than 50 species with many locally endemic taxa, and about 2/3 of them were discovered from limestone areas in north Vietnam, while ca. 1/3 of species were recently described from sandstone forests in the southern part of the country (Gagnepain 1934, Bogner & Arnautov 2004, Bräuchler & Ngoc 2005, Tillich 2005, 2006, 2008, Tillich et al. 2007, Tillich & Averyanov 2008, 2012, Tillich & Leong-Škorničková 2013, Averyanov & Tillich 2012, 2013, 2014, 2015, 2016a, 2016b, Leong-Škorničková et al. 2014, Colin 2015, Averyanov et al. 2016, Vislobokov 2015, Vislobokov et al. 2013, 2014a, 2014b, 2016a, 2016b, Lý & Tillich 2016, 2017).

Aspidistra Ker Gawler (1822: 628) comprises more than 160 species in subtropical SE-Asia, mainly distributed in southern China and adjacent northern Vietnam (Li 2004, Tillich 2005, 2014). In recent years, many new species have been discovered and described from Guizhou Province, southwestern China (He et al. 2011a, 2011b, 2013, Liu et al. 2015, Sun et al. 2014, Xu et al. 2010, 2015a, 2015b). In May 2013, when investigating limestone plants in Guizhou province, we discovered an unusual Aspidistra Ker Gawl. at Dadaihe Karst Tiankeng (Tangbian, Pingtang county), showing dark purplish red flowers, but the pistil was wilted because the plant was at late stage of anthesis. Therefore plants were collected and transferred to the Guilin Botanical Garden, where they flowered next spring. In November 2015, the second author (Meng-Qi Han) collected again the same Aspidistra pecies at Anjiadong Karst Tiankeng (Tangbian). After consulting herbarium specimens and relevant literature on Aspidistra (Huang et al. 2015, Lin et al. 2015, Liang et al. 2016, Ly & Tillich 2016, Pan et al. 2016, Vislobokov et al. 2016), it turned out that the plant represents a new species, which we describe below.

The genus Aspidistra is the most diverse in southern China and northern Vietnam. We describe a new species Aspidistra xuansonensis from northern Vietnam including two varieties: A. xuansonensis var. xuansonensis with greenish white perianth and A. xuansonensis var. violiflora with purple perianth. We present DNA barcoding data of plastid psbA-trnH and nuclear 5SNTS regions for these two varieties in comparison with three other species of Aspidistra. Morphology of monopodial shoots of A. xuansonensis is described in detail. A. xuansonensis resembles recently described A. lingyunensis but differs in longer leaf petioles, longer lamina, perianth tube shape (tubular, widened at the base vs. funnel-shaped), higher anther position, and pistil shape (suddenly obconic to nearly umbrella-shaped vs. obconic gradually widened to stigma).

A new species of the genus Oligodon Fitzinger, 1826, Oligodon nagao sp. nov., is described on the basis of five specimensoriginating from Lang Son and Cao Bang provinces in northern Vietnam, Guangxi Autonomous Region in southernPeople’s Republic of China, and from Khammouane Province in central Laos PDR. This species differs from other speciesof the region by the combination of 15 or 17 dorsal scale rows at midbody, unforked hemipenes, not spinose but withpapillae, entire cloacal plate, a high number of ventrals, a rather short tail and dorsal pattern made of numerous dark,butterfly-shaped blotches. On the basis of the morphology of its hemipenes, Oligodon nagao sp. nov. belongs to the groupof Oligodon cinereus. This new species is compared with other species of the Indochinese Peninsula and China with 15or 17 dorsal scale rows, especially Oligodon joynsoni (Smith, 1917). An updated list of the Oligodon species of this region is provided.

Species of the genus Hebius Thompson, 1913 with 17 or 19 dorsal scale rows at midbody and an overall dark venter are reviewed, including the two species previously known as Parahelicops annamensis Bourret, 1934 and Pararhabdophis chapaensis Bourret, 1934. Specimens with 17 scale rows are morphologically similar to Hebius venningi (Wall, 1910), which is here redefined based on external morphological characters such as scalation, and dorsal and ventral patterns. Consequently, Natrix nigriventer Wall, 1925 is resurrected from its synonymy with Hebius venningi, whereas Natrix taronensis Smith, 1940, previously considered a subspecies of H. venningi or a full species by some authors but without justification, is here confirmed to full species status. Another group of species, mostly similar in coloration and pattern to the H. venningi group but with 19 dorsal scale rows, includes H. modestus (Günther, 1875), H. deschauenseei (Taylor, 1934) and a new species which is described herein based on specimens from northern Vietnam, southern China and north-eastern Thailand due to distinct morphological differences. We also provide updated taxonomic accounts for the species of this group, including an identification key and distribution maps.

Pseudochirita trifoliata, a new Gesneriaceae species from Pu Luong-Cuc Phuong limestone mountain range in northern Vietnam is described and illustrated here. This new taxon is the second species of the narrowly endemic genus Pseudochirita which is known from limestone areas in southern China and northern Vietnam. It is easily distinguished from P. guangxiensis by a set of differences on the leaves, bracts, calyx, external corolla indumentum, staminode number, pistil length, ovary indumentum, style indumentum, and capsule length. A detailed description, illustration, information on distribution, ecology, phenology, provisional conservation assessment using IUCN categories and criteria of the proposed new species, and comparison with its similar species, are also provided.

The genus Aspidistra Ker-Gawler (1822: 628) (Asparagaceae), endemic to East and Southeast Asia, is mainly distributed in southern China and northern Vietnam (Li et al. 2004, Tillich 2006, 2008, 2014, Tillich & Averyanov 2008, Vislobokov et al. 2016). Species of this genus usually set flowers on the ground and hidden in leaves cluster. Flowers of Aspidistra show extremely high diversity in morphological variations. Furthermore, the scentless trait and dull color of flowers of most species make them inconspicuous under forest (Tillich 2005). Relatively, their leaves have lower diversity and taxonomic value. Although individuals of Aspidistra are common under forests in south China and north Vietnam, but it is very difficult to identify them at species level in the field. In recent decades, some scientists have been focusing on this genus and observed the species not only in the field but also in cultivation (Tillich 2005). These combined observations revealed many new species and the number of species known had been dramatically increasing since the 1980s (Lang et al. 1999, Liang & Tamura 2000, Tillich 2008). Just in 2017, at least 11 new taxa including 9 new species and 2 new varieties of Aspidistra were described (Averyanov & Tillich 2017, Averyanov et al. 2017, Lý & Tillich 2017, Lý et al. 2017, Nguyen et al. 2017, Vislobokov et al. 2017, Wang et al. 2017, Xu et al. 2017, Zou et al. 2017). Hitherto, there are around 170 species names of Aspidistra have been accepted based on Lý et al. (2017) and recently published species.
