Phytotaxa319 (3): 283–288

ABSTRACT

Petrocosmea magnifica M.Q.Han & Yan Liu, from eastern Yunnan, China, is described and illustrated. P. magnifica is most similar to P. melanophthalma in having highly reflexed backward and shortly semi-orbicular upper corolla lobes, but it differs by having leaves covered with pannose hairs on both surfaces and cordate at base (Cited from Han et al., 2017).
