摘要

Based on a specimen from Shangsi, Guangxi, China, Peliosanthes reflexa (Aspara-gaceae) is newly described. This species is similar to P. kaoi, but differs from it in the reflexed perianth, flowers drooping or descending, and linear, pale green, erectbracts. Peliosanthes Andrews (Asparagaceae) comprises about 16 species, distributed in India, the Himalaya, Indochina, Malesia, S. China and Taiwan (Chen and Tamura 2000). Peliosanthes, Ophiopogon Ker Gawler and Liriope Loureiro share a unique feature offruit development, i.e., fruit bursting irregularly early in development and exposing seeds with a sarcotesta. Thus, these three genera have been long considered to be related, and they were often grouped in the tribe Ophiopogoneae Endlicher (Conran andTamura 1998). This relationship was confirmed by molecular phylogenetic studies (Yamashita and Tamura 2000, Tamura et al. 2004). Peliosanthes is distinguished from Ophiopogon and Liriope in having leaves subplicate veined with transverse venation between main veins and filaments united into a corona (Chen and Tamura 2000).
