• Resumen

  • A new species of Dendrocalamus Nees (Poaceae, Bambusoideae), D. longivaginatus N. H. Xia, V. T. Nguyen & V. L. Le, is illustrated and described from Phu Tho, Vietnam. This species is known only from the northern provinces of Vietnam: Phu Tho, Yen Bai, and Ha Giang. It is morphologically similar to D. brandisii (Munro) Kurz, a widely distributed bamboo from Thailand, Myanmar, China, and Vietnam, but differs by the ligules of the culm sheath, which are irregularly fimbriate, slightly concave, and 7�9 mm, and by the pseudo-spikelets, which are (5�)13�16 mm with lemmas 9�11.5 mm.
