Although the combination is usually attributed to D. D. Tao (Index Fl. Yunnan. 1: 774. 1984), that work gives only authorities and dates, not places of publication of basionyms, and thus proposed new combinations are invalid. The combination was effectively validated in FRPS, where the full basionym citation is given.
