Pimpinella tomentosa Dalzell ex C.B.Clarke in Hook. f., Fl. Brit. India 2: 689. 1879. Heracleum tomentosum Dalzell & Gibson , Bombay Fl. 108. 1861, non Sm. 1806. Lectotype (designated here): INDIA, s.loc., s.d., N.A. Dalzell s.n. ( K000685483 digital image!); Syntypes: S.loc., s.d., N.A. Dalzell s.n. (CAL [ CAL0000031645 ! CAL0000031646 ! CAL0000031647 !]). Fig. 4

Notes: Dalzell and Gibson (1861) described Heracleum tomentosum , but it is a later homonym for the earliest name published by Smith (1806) and is illegitimate (Art. 53.1, ICN, Turland et al., 2018). Clarke (1879) recognized and ascribed it as Pimpinella tomentosa , attributing the name to Dalzell. In the protologue, he also cited “ Bombay (probably in the Ghats) Dalzell; Concan, Stocks ”. We have traced four sheets; three from CAL (CAL0000031645! CAL0000031646! CAL0000031647!), and one from K (K000685483 digital image!). These sheets appear to have been originally collected by Dalzell, which was later gifted by Mrs. Dalzell to K in 1878, from where they were distributed to CAL. K000685483 has a complete specimen with mature fruits, distinct leaves, and flowers with an additional determinant slip by M.G. Pimenov in 2015 (from personal communication with Laura Pearce, the curator-Botanist, Science Collections, Kew). This sheet, annotated by Clarke as ‘ Pimpinella tomentosa ’, also has Dalzell in pencil label, matches perfectly with the protologue designated here as the lectotype (Art. 9.3, Turland et al., 2018).
