Janeesha, A. P. & Nampy, Santhosh, 2016, Lectotypification of three names in the genus Henckelia Spreng. (Gesneriaceae), Phytotaxa 268 (1), pp. 80-84 : 84

Henckelia ovalifolia ( Wight 1848: t. 1351) Weber & Burtt (1997: 351)

≡ Didymocarpus ovalifolius Wight (1848:10 , t. 1351).

Type (lectotype, designated here):— INDIA, Tamil Nadu, Courtallum, August 1835. 558, Wight 2673 ( E barcode E 00155178!, isolectotypes K barcode K 000858199!, E barcode E 00179262!), Fig. 4 .

Notes:— Wight (1848) described Didymocarpus ovalifolius based on materials collected from Courtallum (Peninsula India Orientalis). Weber and Burtt (1997: 351) transferred this species to the genus Henckelia as H. ovalifolia . No mentioning of a typification is available except Vitek et al. (2000) and Noltie (2005: 276). Vitek et al. (2000) cited only the syntypes: “ India, in Peninsula maderaspatana, Courtallum, Wight 558 ( E, K), Wight 2353 ( K [2])”. According to Noltie (2005), two isosyntypes are available at E “two sheets with HWP label and annotated with the name by Arnott, collected Courtallum August 1835, with the numbers WC 2673 and 1835. 558. one ex herb. Arnott, one from the Glasgow 1903 distribution”. Thus, no one has selected a type for this species. After an exhaustive search, three sheets were found, one at K and two at E, whereas the specimen “Wight 2353” cited by Vitek et al. (2000) was not found anywhere. Among the material traced, the sheet kept in E (barcode E 00155178) with drawings by the author and Herb. Wight label is designated here as lectotype.
