摘要

文、卫、周三位作者对苦苣苔进行了描述和说明。它是生长在中国桂西南石灰岩地区的一种石生植物。根据最大似然（ML）分析，它在一个强大支持的分支（BP=92%）中筑巢，该分支包括P.lui、P.tiandengensis、P.integrifolius、P.albinervius和P.ionophyllus。在这些植物中，星状P.asteriostriatus在形态上最接近整叶P.integrifolius，但可以通过苞片的形状和大小、蒂的毛被、花冠筒的形状和毛被、唇瓣的形状以及花丝的毛被和腺体与之区分。

Petrocodon asterostriatus (Gesneriaceae), a New Species from Guangxi, China

Petrocodon asterostriatus F. Wen, Y.G. Wei & W.C. Chou sp. nova (Gesneriaceae) is described and illustrated. It is a lithophytic species that grows in the limestone area of southwestern Guangxi, China. According to the maximum likelihood (ML) analysis, it nests in a strongly supported clade (BP = 92%) that includes P. lui, P. tiandengensis, P. integrifolius, P. albinervius and P. ionophyllus. Of these, P. asteriostriatus is morphologically closest to P. integrifolius, but can be distinguished from it by the shape and size of bracts, the indumentum of the pedicel, the shape and indumentum of the corolla tube, the shape of the lip lobes, and the indumentum and glands of filaments.
