Heterostemma tsoongii Tsiang (1936: 192)

TYPE:— CHINA, Guangdong, Ling-shan, 9 July 1908, K.K. Tsoong 1840 (lectotype Herb Tsoong, now in PE [ PE 00029445], here designated, isotype IBSC [ IBSC 0005671])

Notes: — Tsiang (1936) indicated the type of H. tsoongii as Tsoong 1840 in Tsoong’s personal herbarium. Specimen [ PE 00029445] is annotated by Tsiang as type for the name and it can be assumed that it originates from Tsoong’s herbarium. However it is impossible to establish if [ PE 00029445] was the only duplicate of Tsoong 1840 in Tsoong’s personal herbarium therefore it is here designated as lectotype.

Heterostemma urceolatum Dalzell (1852: 295) ≡ Oianthus urceolatus (Dalzell) Bentham (1876: 12 t.1191) TYPE:— INDIA, Maharashtra, Karnataka, Belgaum, August, Dr. Ritchie 1112 (lectotype K [K000895025], here designated, isotype E)

Notes: — Swarupanandan et al. (1989) indicated the type of H. urceolatum as ‘ Dalzell s.n. India, Maharashtra, Belgaum Dt. Belgaum (K, photo seen)’ and Kambale et al. (2015) confirmed the lectotypification following Art. 9.9 of the ICN ( McNeill et al. 2012). However, I could not find any specimen of H. urceolatum at K collected by Dalzell. Dalzell (1852) did not indicate any materials for H. urceolatum but stated that the species ‘Crescit rara in collibus prope Belagaum; fl. Julio’.This is likely a reference to Ritchie 1112 [K000895025] from Belgaum and the only specimen of the taxon at K. The sheet has numerous sketches of dissected flowers drawn on the sheet mounting paper itself. The specimen is here confirmed as lectotype for H. urceolatum .

Heterostemma vasudevanii Swarupanandan & Mangaly in Swarupanandan et al. (1989: 257), (as ‘vasudevani’) TYPE:— INDIA, Kerala, Idukki distr., Sabrimala, 1976, K. Swarupanandan 13716 (holotype MH n.v., isotypes CALI n.v., CAL n.v.,

KFRI n.v., K [K000895022], LD n.v.)

Notes: —The isotypes of Swarupanandan 13716 are denoted by a letter added to the collector number. (Starting from A for the holotype, to F for the LD duplicate)
