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 ).

Description. Rosa funingensis : Shrubs climbing, new branches 5-6 m long. Branchlets green, young stems purple-red on sunny side, glabrate; prickles scattered, slightly curved, robust, flat, gradually tapering to broad base. Leaflets including petiole 12-14 cm; stipules mostly adnate to petiole, free parts lanceolate, villous or with short dentate glands at margin, apex acuminate, dry and shrinking when old; rachis and petiole shortly prickly, glandular hairs and villous hairs. Leaves usually 5-7, often 3 near inflorescence, leaflets obovate or oblong, 3-4 x 2-2.5 cm, apex acuminate, leaves leathery, adaxially glabrous, dark green, abaxially villous, purple-red, pale green when mature, margin with sharp single serrations. Inflorescences solitary or several in cyme; peduncle with pedicels 1-2 cm, densely glandular hairs; bracts linear, apex acuminate, 1 x 0.3 cm, margin glandular hairy, with prominent mid-vein. Flowers 7-9 cm in diam.; sepals 5, ovate-lanceolate, abaxially glandular-pubescent, apically caudate, adaxially villous, margin glandular hairs, occasionally linearly divided, reflexed; petals 5, single, white, nearly cordate, apex emarginate, with strong sweet fragrance. Styles connate into a column or not, exserted, light red and the stigma is light yellow. Hips yellow, subglobose, 1.2-1.5 cm in diam., glabrous. 2n = 14. Phenology. Flowering in early April, fruiting from July to October. 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. Conservation status. Based on currently available data, the newly-described Rosa funingensis species and its variants should be assigned to the 'Data Deficient' (DD) category of IUCN (2022). The precise conservation status of the population(s) has not been determined. Further explorations are needed to assess its distribution and conservation status. The known distribution of this species is limited. The type locality of this new species is an unprotected mountainous area. Increasing human activities and habitat destruction may cause a threat to the existence of this rare species.
