Description

Cyperus baronii C.B.Clarke

(Fig. 2)

Journal of the Linnean Society, Botany 20: 289 (Clarke 1883).

LECTOTYPE. — Madagascar • I.1882; R. Baron 695; lectotype (here designated): K[K000362679]) • Same data; Isolectotypes: BM[BM000922483], P[P 00450551].

REMARKS

Clarke (1883: 289) cited two collections in his protologue of the species: “ Madagascar centralis. Baron nn. 484, 695 ”. Out of these two syntypes only Baron 695 is found in various online herbaria (e.g. K, P, and BM). The specimen preserved at P (P00450551) only comprises two inflorescences and a leaf. The specimens preserved at Kew (K000362679) and BM (BM000922483), in contrast, represent complete specimens bearing roots, stems, leaves and an inflorescence and could both serve for lectotypification purposes. The Kew specimen is the better specimen and was verified by Clarke himself; it is here designated as lectotype for this species.
