Didymocarpus villosus D.Don, Prodr. Fl.

Didymocarpus villosus D.Don, Prodr. Fl. View in CoL Nepal. 123. 1825. Lectotype (designated here): NEPAL, s.l., 1819, Wallich s.n. BM (BM [ BM000041747 digital image!]; residual syntype BM [ BM000997734 digital image!]).

Notes: Don (1825) cited “ Hab. in Nepaliâ. Wallich ” in the protologue of Didymocarpus villosus . During our search for the original materials of D. villosus , we located a sheet in BM with 11 plant fragments, bears two barcodes. The barcode BM000047147 (marked as “ Holotype ” in the BM herbarium catalogue) is assigned for three specimens with flowers and fruits mounted on the upper half (marked as ‘a’ in pencil), and BM000997734 for five specimens with flowers and three with fruits in the lower half (marked as ‘b’ in pencil) . BM000047147 bears an anonymous handwritten label, “ Didymocarpus villosa Don. Nepal 1819, Wallich ”, while BM000997734 has a label that reads “ Didymocarpus villosa 14 D.Don ” (in D. Don’s handwriting), and C. B. Clarke’s annotation as “ D. villosa D.Don. ”

Weber et al. (2000) cited “Type, Nepal, Wallich (BM, G)” for D. villosus . The herbarium sheet at G (G00492509) cannot be a type as it was collected from Nepal in 1821, whereas Don’s Prodr. Fl. Nepal. is based on the specimens sent by Wallich to Lambert during 1818–1819 ( Miller 1970; Stafleu & Cowan 1988). BM000041747, which represents well-preserved specimens with flowers and fruits, is designated as the lectotype, and BM000997734 as a residual syntype.
