WANG, HUAN-CHONG, WANG, YUE-HUA & SUN, HANG, 2013, Nomenclatural changes in Rubus (Rosaceae) mostly from China, Phytotaxa 114 (1), pp. 58-60 : 58

Rubus maershanensis Huan C. Wang & H. Sun , nom. nov.

Replaced name: Rubus lutescens Franchet (1890: 206) , nom. illeg., non Boulay (1868: 105). Type:— CHINA. Yunnan: Heqing County, Ma'er Shan, 3500 m, 9 July 1889, J. M. Delavay 3751 (holotype P!, isotypes A!, GH!, NY!, P!).

Etymology: —The specific epithet refers to "Ma'er Shan", the locality of the type collection.

Notes: —In 1890, Franchet (1890: 206) proposed the name Rubus lutescens for a species endemic to southwestern China. Unfortunately, the name R. lutescens had been previously used by Boulay (1868: 105) for a European species, thus Franchet's name is a later homonym of R. lutescens Boulay and is illegitimate. Franchet's species has been recognized as distinct species by most authors since it was described. Therefore a replacement name (nomen novum) for this Chinese species is required and R. maershanensis Huan C. Wang & H. Sun is proposed here.
