Senecio candicans Wall. ex DC. (De Candolle in Wight & Arnott 1834: 22).

Type (lectotype, here designated):— INDIA. Tamil Nadu: Neelgherry [Nilgiri], s.d., R. Wight, s.n., Wight Cat. 1479 ( G-DC, G00468223 , digital image) ( Fig. 1 ); isolectotypes: [ G-DC, G00468339 ; E, E00417015—18 ; K, K000852217—18 ; BM, BM011032527 , digital images] .

Senecio candicans , invalidly (Art. 38.1 of the ICN) published by Wallich (1831:107) based upon the collections by Wight from Neelgherry hills (Nilgiri), which appeared in Wallich catalogue no. 3123. Later, De Candolle (1834) validated the name S. candicans on the evidence of Wallich catalogue no. 3123 and further, Wight’s materials were placed under Catalogue no. 1479. During the study, we have traced out Wight’s homogeneous collection from Nilgiri hills preserved at G-DC, E, K and BM. In G-DC, two specimens are available and both are mounted on a single sheet. Of which, the specimen mounted on the right side of the sheet with barcode G00468223 is preserved well with flowers and achenes, and also congruent with the description and the provenance mentioned in the protologue is designated here as the lectotype. De Candolle also mentioned the name Cineraria sarmentosa Lesch. (De Candolle in Wight & Arnott, 1834: 22) as a synonym of S. candicans and which is being anticipated and considered as a provisional synonym (Art. 36.1 and 50. A (1) of the ICN).
