摘　　要：文章描述了簕竹属孝顺竹亚属一新种——阳山篙竹。阳山篙竹在形态上与撑篙竹(Bambusa pervariabilis McClure)、青秆竹(B.tuldoides Munro)和花眉竹(B.longispiculata Gamble ex Brandis)相似,区别在于阳山篙竹秆基部7~9节具黄绿色条纹,节间及箨鞘背面被暗棕色糙伏毛,箨鞘先端近截平或呈对称性宽拱形,箨鞘内侧先端边缘具卵圆状突起,箨耳近等大,不下延。The paper describes Bambusa yangshanensis,a new species of Bambusa subg.Leleba.The new species is similar to B.pervariabilis McClure,B.tuldoides Munro and B.longispiculata Gamble ex Brandis in morphology,but it can be easily distinguished by the yellow-green stripes on basal 7 to 9 internodes,dark brown strigose at internodes and culm sheath,nearly truncate or symmetrically arched culm sheath apex with an oval protuberance at the edge of the inner side,and the subequal and not slanted culm auricle.
