Abstract
A new species of Capparis, C. phatadke, is described and illustrated from the Bolikhamxai Province, central Lao PDR. The new species is characterized by lianous habit, brown-reddish indumentum, straight stipular thorns, laminar bracts, large flowers arranged in terminal corymbs or subumbels, long filaments and large ovary. It is so far known from a single locality, where has been observed in mixed deciduous forest and secondary forest in a limestone area. Its ecology and phenology are discussed, and its conservation status is assessed.
