Abstract A new species of the genus Indocalamus (Gramineae) from South Yunnan, China,
I. jinpingensis Yi & J. Y. Shi, is described and illustrated. The new species is similar to I.
victorialis Keng f. in habit, but differs by branch solitary at each node of culm, internodes
solids or nearly solids, infranode densely covered with a ring of pale tomentum, not striped,
intranode densely pale tomentose, culm-node very swollen on one side; culm-sheaths
glabrous or sparsely brown adpressedly tuberculate hispidulous, pubescent at base; leaves 4–5
at ultimate branchlets, leaf-sheaths lossy when fresh, violet near apex, blades with 9–12
lateral veins on each side.
Key words Indocalamus, Indocalamus jinpingensis Yi & J. Y. Shi, Gramineae, new species,
Yunnan, China.
摘要 报道了产于云南南部的禾本科Gramineae箬竹属Indocalamus一新种——金平箬竹I. jinpingensis
Yi & J. Y. Shi。该新种在形体上相似胜利箬竹I. victorialis Keng f., 但秆每节仅1分枝, 节间实心或几实
心, 节下密生一圈灰白色绒毛, 无纵肋纹, 节内密被灰白色绒毛, 秆环一侧很隆起; 箨鞘背面无毛或被
稀疏棕色贴生瘤基小刺毛, 而基部被微毛; 末级小枝具叶4–5, 叶鞘新鲜时很光亮, 上部紫色, 叶片具
次脉9–12对, 易于区别。

作者在《中国竹类》野外图片拍摄过程中, 于2006年4月在云南金平县海拔1500 m左
右的勐桥乡新寨村火山自然村的山脊常绿阔叶林下见到了一种类似筇竹Qiongzhuea
tumidinoda Hsueh & Yi的大节疤竹子, 现场初步认定为箬竹属Indocalamus Nakai一新种,
并进行了调查、采集和拍照。嗣后又将其与产于江西井冈山的大节赤竹Sasa magnonoda T.
H. Wen & Liao作了进一步对比研究, 确认它们之间存在植株矮小, 节很膨大, 每节仅1分
枝, 叶大等相似之处, 但本种节下有一圈灰白色绒毛带; 从植物区系上看, 我国西南地
区尚无赤竹属Sasa Makino & Shibata或Sasaella Makino成员的分布, 故最后仍作箬竹属
新种处理。
