Graffenrieda weddellii Naudin (1852: 117-118)

Type (lectotype, designated by de Lima et al. 2017):— BRAZIL. “In Brasilia occidentali ad scatebras fuminis dicti Paraguay, prope pagum vulgo Diamantino, provinciae Mato Grosso ”, December 1844, M.H.A. Weddell 3050 (P02274684 [digital image!], isolectotypes: F937003 [fragments] [digital image!], P02274685 [digital image!]).

= Graffenrieda ovalifolia Naudin (1852: 117)

Type (lectotype, inadvertently designated by Wurdack & Renner 1993):— GUYANA. “In Guyana anglica, prope Roraima”, 1846, M. Schomburgk 568 (P02274686 [digital image!], isolectotypes BM001191483!, BR518563[fragments] [digital image!], F [cited by Lima et al. 2017 but not seen], G [cited by Lima et al. 2017 but not seen], K000329494!).

Notes: When Naudin (1852) described G. ovalifolia he mentioned the specimen Schomburgk 568, of which there are duplicates at BR, BM, F, G, K and P. Wurdack & Renner (1993) cited the specimen at P as the holotype. This constitutes an inadvertent lectotypification according to Art.7.11. Note 2 ( Turland et al. 2018). It should be noted that Martin & Cremers (2007) also mentioned the P specimen as the holotype. Presumably they did this not interpreting Wurdack and Renner (1993) as a lectotypification, but following tradition of assuming that the specimen at the home institution of the author was considered the holotype.
