Heterostemma dalzellii Hooker (1883b: 48) [Jun 1883]

TYPE:— INDIA, Vingorla, July 1852, N.A. Dalzell s.n.. (lectotype K [K000895026], designated by Kambale et al. (2015))

Notes: — Heterostemma dalzellii was based on specimens ‘ Heterostemma sp. 2 , The Concan; at Vingorla and Malwan, Dalzell, Stocks ’. Dalzell s.n. [K000895026] was selected as lectotype for the name by Kambale et al. (2015). A syntype of Stocks s.n. is present at P [P03899001]. Despite Hooker (1883b) cited the Stocks specimens as ‘ Heterostemma sp. 2 ’ it is likely that Stocks s.n labelled as ‘ Heterostemma (3)’ at CAL [ CAL 17963] and K [K000895027, one not barcoded] are syntypes of H. dalzellii as Hookers’ Heterostemma sheets appear to be misnumbered (see also H. stellatum ).

Heterostemma deccanense (Talbot) Swarupanandan & Mangaly in Swarupanandan et al. (1989: 255) (as ‘ decanense ’) ≡ Oianthus deccanensis Talbot (1911: 260) [1911]

TYPE:— INDIA, Maharashtra, Deccan Ghats, 18 miles west of Poona, August, W.A. Talbot s.n. (not found)

Notes: —No Talbot material was located at BLAT, BM or K by Swarupanandan et al. (1989) and I confirm that there is no suitable lectotype of H. deccanense at BM or K. A neotype for H. deccanense will have to be selected when Heterostemma is revised.
