REMARKS

The name Cyperus baikiei was mentioned by Clarke (1894: 550) in the Conspectus Florae Africae, indicating its origin (“Afr. occ.-bor.: Sierra Leone, Scott Elliott [sic] 5676. Afr. occ.: Bas Niger ”) but without a description or diagnosis ( nomen nudum). Kükenthal (1925: 325), who validated the name, provided the following collection details: “Trop. Westafrika: Senegambien, Ufer des Bani ( A. Chevalier no. 1086!); Sierra Leone, zwischen Bumban und Port Lokko ( Scott-Elliot no. 5676!); Niger ( Baikie!)”. The Chevalier collection, that should be in P ( Stafleu & Cowan 1976 - 1988), could not be traced. The latter two gatherings are preserved at K. The Scott-Elliot gathering, to which was already referred by Clarke, comprises a complete but young individual, with the inflorescence barely exserted from the upper leaves (barcode K000321313). The third syntype, the Baikie collection that is preserved at K, bears three complete specimens, two of which with a mature inflorescence (barcode K000321312). A duplicate of the Baikie collection is preserved at B (B 10 0166379); it was annotated by G. Kükenthal in 1923.

The latter Kew specimen is designated as the lectotype of the name Cyperus baikiei .
