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

Henckelia lyrata ( Wight 1848: t. 1350) Weber & Burtt (1997: 349)

≡ Didymocarpus lyratus Wight (1848: 10 , t. 1350).

Type (lectotype, designated here):— INDIA, Tamil Nadu, Courtallum, September 1835. 559, Wight 2674 ( E barcode E 00155173!, isolectotypes E barcodes E 00155174!, E 00155175!), Fig. 1 .

Notes:— Henckelia lyrata was originally described as Didymocarpus lyratus by Robert Wight (1848) from South India with the citation “Courtallum, in moist shady places, flowering August and September”. Vitek et al. (2000) cited the type as “ India, Courtallum, IX. 1835. Wight 2354 ( E, K); s. dat. Wight 559 ( K, L)”. Noltie (2005: 275) also indicated three isosyntypes at E.

While searching for Wight’s original material in various herbaria, we traced six sheets, three each at E (barcodes E 00155173!, E 00155174!, E 00155175!) and K (barcodes K 000858185!, K 000858186!, K 000858187!) and none at L ( R. Bijmoer pers. comm.), as indicated by Vitek et al. (2000). The sheets K 000858185 and K 000858186 have the Herb. Wight label, numbered 2354 while the third sheet K 000858187 has an annotation “ Didymocarpus lyrata, Ic. t. 1350, Courtallum 559”. All the three sheets at E have Herb. Wight label numbered 2674, but there is no material kept in E with the number 2354, as indicated by Vitek et al. (2000). Among the material traced, only the sheet “ Wight 2674” kept in E (barcode E 00155173) has drawings of the dissected floral parts as depicted in the iconography. It matches exactly with the protologue and is designated here as lectotype.

Henckelia meeboldii (Smith & Ramaswami 1914: 43) Weber & Burtt (1997: 349) ≡ Didymocarpus meeboldii Smith & Ramaswami in Smith (1914: 43). Type (lectotype, designated here):— INDIA, Kerala, Peermade Ghat, Meebold 12851 (CAL barcode CAL0000019179!, isolectotypes

CAL barcodes CAL0000019180!, CAL0000019181!, CAL0000019182!, K barcode K000858198!, E barcode E00155177!), Figs 2

& 3 .

Notes:— Henckelia meeboldii was first described as Didymocarpus meeboldii by Smith and Ramaswami in Smith (1914: 43) and in the protologue cited: “ Didymocarpus meeboldii , Southern India —at Peermade Ghat, No. 12851 Meebold”. Vitek et al. (2000) cited the type as “South India, Peermade Ghat, 1910-1911, Meebold 12851 (K & E)”, without designating a lectotype. The search for the type specimens in various herbaria revealed that in addition to the specimens cited by Vitek et al. (2000) kept in K (barcode K000858198) and E (E00155177), there are four more sheets in CAL (barcodes CAL0000019179!, CAL0000019180!, CAL0000019181!, CAL0000019182!). Among the material traced, only the sheets kept in CAL (barcodes CAL0000019179 and CAL0000019180) have drawings of dissected floral parts and annotations by the authors. The sheet CAL0000019179 matches exactly with the protologue and is designated here as the lectotype.
