Heterostemma menghaiense (Zhu & Wang) Gilbert & Li in Gilbert et al. (1995: 9) [27 March 1995] ≡ Heterostemma villosum var. menghaiense Zhu & Wang (1994: 27)

TYPE:— CHINA, Yunnan, Xishuangbanna, Menghai, Mengsong, 1000 m, 6 May 1989, H. Zhu & H. Wang 2443 (lectotype HITBC [ HITBC 62875], here designated, isotypes HITBC [ HITBC 62876, HITBC62877, HITBC 62878])

= Heterostemma ferrugineum C.Y.Wu nom . nud. (Name annotated by C. Y. Wu on numerous specimens in KUN)

= Heterostemma ferruginevillosa H.Chu & H.Wang nom . nud. (Name annotated on type collections of Heterostemma menghaiense in HITBC)

Notes: — Gilbert et al. (1995) mentioned the holotype of Heterostemma menghaiense as Zhu & Wang 2443 (HITBC) collected on 14 May 1989. Upon examination of materials at HITBC I have found four duplicates of Zhu & Wang 2443, collected on 6 May 1989. Therefore the collection date needs to be corrected and a lectotype must be selected. The duplicate [HITBC62875] is a well-preserved fertile specimen with a drawing of the pollinia and is here selected as lectotype for H. menghaiense .
