Wang, Huan-Chong, 2014, Two replacement names in Asian Rubus (Rosaceae), Phytotaxa 172 (3), pp. 293-296 : 293

Rubus austrosinensis Huan C.Wang , nom. nov.

Replaced name: Rubus crassifolius T.T.Yu & L.T.Lu (1982: 460) , nom. illeg., non Genevier (1868: 236).

Type: — CHINA. Guangxi: Xing’an county, Mao’er Shan , June 1953 , Guangxi Exped. 4235 (holotype PE-00020733!, isotype PE- 01833205!) .

Etymology: —The new specific epithet, austrosinensis , referring to the geographical range of the newly named species, derives from the Latin austro -, meaning “south”, Sina , meaning “ China ”, and Latin suffix -ensis, meaning “of” or “belonging to”.

Distribution: —Endemic to south China.

Notes: —In 1982, Yu & Lu (1982: 460) proposed the name Rubus crassifolius for a species endemic to southern China and placed it in their R. subsect. Stipulosi T.T.Yu & L.T.Lu (1982: 460). However, the name R. crassifolius had been previously used by Genevier (1868: 236) for a European species, thus Yu & Lu’s name is a later homonym of R. crassifolius Genevier and is therefore illegitimate. Yu & Lu’s species belongs to R. subg. Malachobatus and is distinctive amongst members of this group in its flowers solitary, rarely 2-3, the inflorescences, calyces and abaxial surfaces of leaves densely yellowish-brown sericeous-villous, and the stipules suborbicular or broadly ovate, 1.5-2 cm long. There seems to be no available synonym for this Chinese species, therefore a replacement name (nomen novum) is required and the new name, R. austrosinensis Huan C.Wang , is proposed here.
