摘要/Abstract

摘要： 本文描述了中国西藏墨脱县发现的浆果类秋海棠属植物一新变种——德尔贡秋海棠Begonia burkillii Dunn var. deergongensis W. G. Wang, Z. X. Wang & J. Y. Shen。该变种在形态上与伯基尔秋海棠B. burkillii最近似，但其叶柄有凹槽，雄花花被片2（–4）枚，雌花花被片2枚，花被片顶端圆钝；其次也近似于香花秋海棠B. handelii，但其根状茎短、纤细，叶柄、花被片和子房有红斑，雄花花被片2（–4）枚，雌花花被片2枚，可明显区分。文中提供该变种详细的形态学描述、地理分布、物候特征及彩色图片，并依据《IUCN红色名录分类与标准指南》评估其保护等级。

Abstract: Begonia burkillii Dunn var. deergongensis W. G. Wang, Z. X. Wang & J. Y. Shen, a new variety with berry-like fruits, from Medog County, Xizang, China, is here confirmed and described. The new variety shows morphological similarities most similar to B. burkillii, but can be significantly distinguished from B. burkillii by its grooved petiole. The staminate flowers have 2(–4) tepals, while the pistillate ones have 2 tepals, and the tepal apices are rounded and obtuse. It is also similar to B. handelii, yet differs clearly by the short, slender rhizome and the red spots on the petiole, tepals, and ovary, as well as by having 2(–4) tepals in staminate and 2 tepals in pistillate flowers. Detailed notes on morphology, distribution, and phenology, as well as colour photographs, are provided. The conservation status of the new variety is assessed in accordance with the Guidelines for Using the IUCN Red List Categories and Criteria.
