摘要:

 我国竹亚科空竹属 (Cephalostachyum Munro) 植物发现于云南和西藏两省区,集中分布于云南。根据形态学性状,以及近年来叶片微形态和分子系统学研究结果,作者对我国空竹属物种进行了整理并编制了分种检索表。结果显示,我国空竹属现知有7种,云南均有分布:薄竹 (Cephalostachyum chinense (Rendle) DZ. Li et HQ. Yang)、空竹 (Cfuchsianum Gamble et Hook. f.)、独龙江空竹 (Cmannii (Gamble) Stapleton et DZ . Li)、小空竹 (Cpallidum Munro)、屏边空竹 (Cpingbianense (Hsueh et YM. Yang ex Yi et al.) DZ. Li et HQ. Yang)、红毛空竹 (Csanguineum (WP. Zhang) DZ. Li & HQ. Yang)、真麻竹 (Cscandens Bor)。薄竹属 (Leptocanna Chia et HL. Fung) 和毒空竹 (Cvirulentum YM. Yang et F. Du) 分别为空竹属和空竹的异名。另一方面,原置于空竹属的香糯竹 (Cpergracile Munro) 和金毛空竹 (Cvirgatum (Munro) Kurz) 的形态特征则更接近狭义的竹属 (Schizostachyum Nees),应该处理为狭义竹属成员。本研究对空竹属今后的修订工作有重要意义。

Abstract:

Species of Cephalostachyum Munro (Poaceae: Bambusoideae) from China are distributed in Yunnan and Tibet, mainly in Yunnan. In this paper, we discussed species of Cephalostachyum and compiled a key to species from China, based on recent studies on micromorphological characters of leaf epidermis and molecular phylogenetics of paleotropical woody bamboos. There is a total of seven species of Cephalostachyum distributed in China, all in Yunnan: Cchinense (Rendle) DZ. Li et HQ. Yang,  Cfuchsianum Gamble et Hook. f., Cmannii (Gamble) Stapleton et DZ. Li, Cpallidum Munro, Cpingbianense (Hsueh et YM. Yang ex Yi et al.) DZ. Li et HQ. Yang, Csanguineum (WP. Zhang) DZ. Li et HQ. Yang and Cscandens Bor. Leptocanna Chia et HL. Fung and Cvirulentum YM Yang et F. Du are synonyms of Cephalostachyum Munro and Cfuchsianum Gamble et Hook. f. respectively. On the other hand, Cpergracile Munro and Cvirgatum (Munro) Kurz are morphologically closer to Schizostachyum Nees than to Cephalostachyum, and they should be treated as members of Schizostachyum. This paper is of significance to a worldwide revision of Cephalostachyum.
