荨麻科楼梯草属三种植物花序的补充描述(英文)

Supplementary Description of Inflorescences of Three Species in Elatostema (Urticaceae)

楼梯草属的花序不但是反映该属进化趋势的重要器官之一,而且还是该属的属下划分及种间鉴定的关键性状。本文基于大量的有花标本研究,并参照模式标本及相关文献资料对该属的三种植物花序形态进行了补充描述。

The inflorescence of Elatostema is not only one of the key characters helpful to understand the evolutionary trend in various infrageneric taxa, but also plays important role in the delimitation of its sections and series. In this paper, based on careful examinations of inflorescences from several voucher specimens including type and literatures, the description of inflorescences of three species in this genus was presented.
