A clambering bamboo endemic to northern Vietnam is shown to represent a new species, M. trangdinhensis H.N.Nguyen & V.T.Tran (Gramineae: Bambusoideae‐Bambusinae), which is described and illustrated. It is similar to M. tonkinensis in general appearance, but differs by being covered with appressed white hairs, and by auricles lacking or forming a low rim only, smaller leaf blade 20–24 × 2.3–2.5 cm, and smaller glumes 6–7 × 4.0–4.5 mm. A key to all species of the genus is included.
