摘　　要：描述了竹亚科牡竹属一新种——长耳吊丝竹（Dendrocalamus Iongiauritus S．H．Chen，K．F．HuangetR．S．Chen）。该种与吊丝竹（D．minor（McClure）ChiaetH．L．Fung）相近似，但该竹种部分节有明显发达的一条主枝，箨耳较大，明显并与箨片基部相连，窄长，横卧于箨鞘两肩，且呈有规则皱褶状，并着生有6～8mm长的波曲燧毛，箨舌高达0．7～0．9cm，呈不整齐撕裂状，上部有灰黄色扁形长毛，易于区别。A new species of the genus Dendrocalamus Nees of Bambusoideae from China, D.

The new species is similar to D. minor （McClure） Chia et H. L. Fung, but differs by having one dominant branchlet at some nodes, culm-sheath auricle that is larger and distinct, long and narrow, connected with the base of the culm-sheath blade, regularly fold shape, wavilness oral setae 6-8 mm, sheath ligule 0.7-0.9 cm high, irregularly tearing shape, with gray-yellow flat long ciliates on the upside.
