Heterostemma disciflorum (Hooker) Swarupanandan & Mangaly in Swarupanandan et al. (1989: 256) ≡ Oianthus disciflorus Hooker (1883b: 49)

TYPE:— INDIA, Karnataka, Concan ; ‘ Heterostemma (2)’ Stocks s.n. (lectotype K [K000895024], designated by Kambale et al. (2015), isotype K [K000895023])

Notes: —The description of H. disciflorum was based on a specimen cited as ‘Western Peninsula, the Concan? Herb. Law. and Stocks ’. Swarupanandan et al. (1989) indicated the type of H. disciflorum as ‘Law & Stocks s.n. (K, photo seen), India, Karnataka, Concan and Mysore’. I have located two sheets at K both bearing two labels, one is a Herb. Ind. Or. Hook. fil. & Thomson printed label, bearing locality as Concan, and collector Stocks s.n., the other from Canara & Mysore Mr Law? s.n. Since the attribution of the specimens to Law is doubtful I refer to these as Stocks s.n. Both specimens are well preserved, fertile and bear a manuscript dissection of the flowers. The duplicate [K000895024] was selected by Kambale et al. (2015) as lectotype for H. disciflorum .

Heterostemma esquirolii (Léveillé) Tsiang (1936: 189) ≡ Pentasachme esquirolii Léveillé (1914: 43) [1914] TYPE:— CHINA, Kouy-Tcheou, Trou du hoeu hay tse, 9 August 1909, J. Esquirol 716 (lectotype E [E00275187], here designated, isotype

Notes: —The description of P. esquirolii was based on ‘Trou du Hoeu Hay Be, J. Esquirol 716. Can Chouen, J. Cavalerie 3973, Aout 1905.12’.

The Esquirol 716 duplicate located at E is a complete and well-preserved specimen and is designated as lectotype for H. esquirolii . A syntype Cavalerie 3973 is present at E [E00275188] and P [P03899037].
