Abstract
A new species Rosa funingensis and its variant R. funingensis f. rosea, both collected from Yunnan Province, China, are, for the first time, documented and illustrated in this study. Morphological analysis in comparison with two related species in the wild, R. gigantea and R. rubus, presents distinguishable features through leaf surfaces, inflorescences and the shape of styles. R. funingensis leaf surfaces are abaxially villous, purple-red, pale green when mature, adaxially glabrous, dark green; inflorescences solitary or 2–5(7) in corymbose cyme; and styles connate into a column or not, exserted.

Diagnosis: Rosa funingensis is mostly similar to R. gigantea. However, Rosa funingensis differs significantly from R. gigantea by having leaves abaxially villous, purple-red, pale green when mature, adaxially glabrous, dark green (vs. both surfaces glabrous), rachis and petiole shortly prickly, glandular hairs and villous (vs. sparsely shortly prickly and glandular pubescent), inflorescences solitary or 3–5(7) in corymbose cyme (vs. solitary or 2 or 3 and fasciculate) and styles connate into a column or not (vs. free) (Table 1).
Etymology: The species epithet refers to Funing County, where the new species was first discovered. The variant with pink flower colour is proposed to be named “Rosa funingensis f. rosea”.
Distribution and habitat: New species are currently known from Funing County, Wenshan Zhuang and Miao Autonomous Prefecture in eastern Yunnan, at elevations between 400 m and 1400 m. They grow on hillsides, roadsides and riversides.
