摘要:

报道了云南苦苣苔科植物一新种,即光喉石蝴蝶 (Petrocosmea glabristoma ZJ. Qiu & YZ. Wang),并进行了详细描述和比较以及分子系统学证实。该新种在形态上和大理石蝴蝶 (Pforrestii Craib) 以及东川石蝴蝶 (Pmairei Lévl.) 相似,但叶片三角形或三角状卵形,花冠内面,尤其在喉部,光滑无毛,花丝显著较短明显区别于后者。

Abstract:

Petrocosmea glabrstoma ZJ. Qiu & YZ. Wang, a new species from Yunnan Province, China, is described and illustrated. The new species is similar to Petrocosmea forrestii Craib and Pmairei Lévl., but differs from them mainly by its leaves triangular or triangularovate, corolla glabrous inside with shorter filament. Molecular and morphological data demonstrate that this new species has a close affinity to Pforrestii.

Key words: Gesneriaceae, Petrocosmea, New species, Yunnan, China
