Two new species of Schizostachyum Nees (Poaceae: Bambusoideae): S. yalyense N. H. Xia, V. T. Tran et H. N. Nguyen and Schizostachyum ninhthuanense N. H. Xia, V. T. Tran et H. N. Nguyen (Poaceae: Bambusoideae) are described and illustrated from Vietnam. Schizostachyum yalyense is similar to S. lima (Blanco) Merrill, but differs by culm sheaths with a concave apex 4–5 cm wide and 1.0–1.5 cm deep, pseudospikelets clustered on the wholly leafless flowering branches, possession of 2 bracts and lodicules. Schizostachyum ninhthuanense is related to S. hainanense Merrill ex McClure, but differs by culm sheaths covered with white hairs and having white–brown hairs at the apex, ligule margin densely pale‐ciliate, pseudospikelets clustered on wholly leafless flowering branches, presence of 3 lodicules, two stigmas apically on the style and the third stigma branching off from one of the two other stigmas.
