This combination was first published by Steenis (Blumea 7: 595. 1954), but not validly, because the place of publication of the basionym, as required by the ICBN since 1953 (St. Louis Code, Art. 33.3), was not cited.

Slopes and valleys in evergreen forests; 800--1500 m. Fujian, Guangdong, Guangxi, Hainan, S Hunan, Jiangxi, SE Yunnan [Laos, N Vietnam].
