自我国著名竹类学家耿伯介教授在1957年建立玉山竹属以来,这个属现已发表新种和新组合10余种。作者对本属作了较详尽的采集和研究,根据整理和统计,现已知本属共有47种。除Y. jaunsarensis(Gamble)Yi(=Y. anceps(Mitf.)Lin产喜马拉雅西北部),Y. rolloana(Gamble)Yi产印度阿萨姆邦,Y. alpina(Schum.)Lin产非洲刚果等3种外,其余43种均产我国。本属是亚热带高山区域所特有的一群竹类,垂直分布都在海拔1300—3500米之间。本文主要按其秆之每节分枝数目多少将本属划分成两个组:鄂西组Sect. I. Confusae Yi和玉山竹组Sect. Ⅱ. Yushania。限于篇幅,本文仅刊载24新种和3新组合。
Since the famous bamboo scholar in China, Professor Geng Bo-chieh founded in 1957, the genus of Yushan, this genus has now published more than 10 new species and combinations. The author made a more detailed collection and research on this genus, and according to the collation and statistics, there are 47 known genus now. Except Y. jaunsarensis (Gamble) Yi (= Y. anceps (Mitf.) Lin produced in the northwestern Himalayas), Y. rolloana (Gamble) Yi produced in Assam, Y. alpina (Schum. 3 species, the remaining 43 species are produced in our country. This is a subtropical alpine region unique to a group of bamboo, vertical distribution at an altitude of 1300-3500 meters. In this paper, the genus is divided into two groups according to the number of branches of each stalk: Sect. I. Confusae Yi of Hubei Province and Sect. Ⅱ. Yushania Group of Hubei Province. Due to space limitations, this article contains only 24 new and 3 new combinations.
