西藏特有竹子Arundinaria macclureana的名实辨正

Arundinaria macclureana是在现代植物学中根据在西藏采集的标本描述的第一个竹子。其模式标本是1938年采集的，但只有花枝，没有地下茎、秆箨等重要特征。尽管如此，该种还成为了新属Borinda的模式种。在研究了其模式标本后，使本文第一作者联想起1991年在藏东南采集的西藏箭竹（Fargesia setosa）。西藏箭竹的模式标本采集于1977年，但只有营养体，没有花枝。在对比研究两个名称的模式后，确认二者实为同种。经与共同作者一起讨论，认为其正确学名为Fargesia macclureana，但该种所在的筱竹属群的关系还有待进一步的研究。

The Identity of an Endemic Tibetan Bamboo, Arundinaria macclureana (Gramineae, Bambusoideae)

Arundinaria macclureana Bor was the first bamboo described in modem taxonomy based on Tibetan material. Since the type bears only flowering branches without critical vegetative characteristics such as rhizomes and culm-sbeaths, its identity has long been doubtful. Even so, it provides the type of a newly created genus, Borinda. By checking the type specimens of A. macclureana as well as the type of Fargesia setosa T. P. Yi, which is a species only known by its vegetative state, and by collecting in the field, a conclusion is reached that these two entities am couspecific. Fargesia macclureana, a name published in less-received literature is the correct name for this endemic Tibetan bamboo, although re-evaluation of the relationships within the Thamnocalamus group is needed.
