摘要/Abstract

摘要：

孟连秋海棠 (Begonia menglianensis YY. Qian) 曾被归并到歪叶秋海棠 (Begonia augustinei Hemsl.)。经过对比模式标本和模式产地标本，作者发现孟连秋海棠是个独立的种，在果的形态上它与大王秋海棠 (Begonia rex Putz.) 最为相似，但果实上最大翅的上缘有一个近三角形的平面可以很容易将二者分开。作者提供了该种的形态描述，并对花粉和种子形态进行了扫描电镜观察。

Abstract:

Begonia menglianensis YY. Qian was regarded as a synonym of Begonia augustinei Hemsl. After comparing the type and additional collections made from the type locality, we found that this species is distinct, and mostly similar to Begonia rex Putz. in its fruit morphology. However, it can be easily distinguished by its flat and nearly triquetrous superior edge of the major fruit wing. Together with information on its pollen and seeds observed under Scanning Electronic Microscope, a revised description for Bmenglianensis is provided.
