摘要: 通过对广义形态学性状特征的观测、统计和分析,比较了藏扇穗茅、扇穗茅和寡穗茅这3个近缘物种的主要性状差异,以探讨藏扇穗茅的系统分类归属。结果显示,在外部形态上藏扇穗茅与扇穗茅差异甚小,难以区分,但与寡穗茅差异明显,是典型的物种间关系;在叶表皮微形态解剖特征上,藏扇穗茅的绝大多数特征与扇穗茅的一致或类同,但与寡穗茅却存在明显间断。故研究认为,藏扇穗茅与扇穗茅隶属于同一个物种,藏扇穗茅应作为扇穗茅的异名处理。

Abstract: We analyzed the differences among nearest related Littledalea tibetica, L.racemosa and L.przevalskyi in the genus Littledalea by morphological observation and anatomical analysis of leaf epidermises. There was very slight disparity between L.tibetica and L.racemosa in external morphology, the classification of the two species is very difficult, and the differences between L.tibetica and L.przevalskyi are distinct, the two taxa are two different species. Anatomically, the most features of L.tibetica are consistent with or similar to that of L.racemosa, while for L.przevalskyi, the discontinuity of characters between them is obviously present. Therefore, L.tibetica and L.racemosa should belong to the same species, and L.tibetica can be classified to synonymy of L.racemosa.
