无量山小檗与藤小檗的名实问题

The Identity of Berberis wuliangshanensis C. Y. Wu ex S. Y. Bao and B. jingguensis G. S. Fan et X. W. Li (Berberidaceae)

摘要:

通过标本检查及原始文献分析，认为无量山小檗 Berberis wuliangshanensis C. Y. Wu ex S. Y. Bao与藤小檗 B. jingguensis G. S. Fan et X. W. Li在主要形态特征方面基本相同，不同点均在一定变异范围内，且两种植物的模式标本产地及生境条件也较相似，都生长在云南省无量山海拔2 500 m上下的常绿阔叶林中，故将藤小檗处理为无量山小檗的异名。

Abstract:

After examining the type specimens and the original literatures of Berberis wuliangshanensis C. Y. Wu ex S. Y. Bao and B. jingguensis G. S. Fan et X. W. Li, little difference was found between these two species in the key morphological characteristics. Though B. jingguensis was ever described as a new species for its unusual feature of being a woody liana, however, such a “woody liana” character was also mentioned in the field note of a few specimens of a shrub species of B. wuliangshanensis, and could be resulted from a false field record, consequently, this character should be explained as an arching habit of the stem spreading out by its spines. In addition, the type specimens of both species were collected in the evergreen broad-leaved forests of Wuliangshan Mountain at elevation around 2500 m in Yunnan Province, China. Thus, B. jingguensis is treated as a synonym of B. wuliangshanensis.
