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.关键词
