本文记述并插图了产于云南东部的一种叫中国(Petrocosmea Grand)的新种。壮丽山杨与紫云英最为相似。黑眼病的特征是上花冠裂片向后高度反折，呈半圆形，但不同之处在于叶的两面都覆盖着红褐色的毛，而底部为心形。
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.
