The genus Capparis L. is represented by between 250–400 species in the world (Zhang and Tucker, 2008). Capparis species have been known as a good food resource because its floral buds and fruits contain minerals, protein, carbohydrates, lipids and vitamins (Prashant et al., 2016). However, it is difficult taxon to identify taxonomically because their vegitative characters are similar and confued without sexual characters. Up to now, 36 species, 3 subspecies, and 2 varieties are reported including one new species which discovered recently in Vietnam (Thuong et al., 2013, 2015, 2016). An additional new record species was found during regular field trip between Institute of Ecology and Biological Resources (IEBR) and Korea Research Institute of Bioscience and Biotechnology (KRIBB) to Loc Binh District, Lang Son Province in 2015 (Fig. 1). Morphological characters of this plant were matched with another unidentified specimen which was housed in the herbarium of Institute of Medicinal Materies (HNPM) and the herbarium of Vietnam Forest Museum (VFM) of Forest Inventory and Planning Institute. Finally, we identified them as a C. pubifolia through careful checking a type specimen and literature survey (Jacobs, 1965; How, 1979; Pham, 1999; Wu, 1999; Zhang and Tucker, 2008). It is morphologically allied to C. sikkimensis Kurz but differs by gray-yellow color of hair on twigs, having more number of secondary vein on leaf, trichomes on both surfaces of petal and globose shape of fruit (Table 1). This taxon was found only from Guangxi and Yunnan areas of China (Zhang and Tucker, 2008) but never recordedin Vietnam. A detailed description along with line drawing and photographs (Figs. 2, 3) has been provided to support species identification.
