W. C. Ko (in FRPS 71(2): 112. 1999) attributed this name to Puff (Opera Bot. Belg. 3: 285. 1991). However, Puff attributed this name to Li in unpublished work and provided no Latin diagnosis or designation of a type, so this name was not validly published by him. Li cited only three collections in her article in Novon and none were specimens cited by Puff, so the specimens cited by Puff do not actually seem to be paratypes as has been suggested.
