Abstract
Argostemma Wall. is a large genus of herbaceous plants in the tribe Argostemmateae (Rubiaceae–Rubioideae), mainly distributed in Southeast Asia and its taxonomy is far from completely known. Eight species of Argostemma were previously reported from Laos, but we here add six more species (Argostemma lamxayanum, A. lobbioides, A. longisepalum, A. paksongense, A. svengsuksae and A. vientianense) which are all new to science. The new species were found in limestone habitats in southern and central Laos. Detailed descriptions, illustrations, photographs and a key to all the known species in Laos are provided.
