Centemopsis Schinz

Schinz (1911: 242) validly described the genus Centemopsis through a detailed diagnosis. Schinz (l.c.) listed 4 Centemopsis species each one with synonyms and distribution; a diagnostic key at species level was also given. These four species names [ C. biflora ( Schinz 1893: 107) Schinz (1911: 243) , C. rubra ( Lopriore 1900: 49) Schinz (1911: 243) , C. glomerata ( Lopriore 1900: 49) Schinz (1911: 243) , and C. kirkii ( Hooker 1880: 31) Schinz (1911: 243) ] can be considered as syntypes and one of them should be selected as lectotype (Arts. 9.2, and 9.5). On the basis of the current species circumscriptions in Centemopsis (see e.g., Townsend 1985: 50, Hedberb & Edwards 2009, SANBI 2012a), the name C. rubra is an heterotypic synonym of C. kirkii . C. biflora is sometimes also considered as a synonym of C. kirkii and it deserves further nomenclatural and taxonomical investigations (see e.g., Townsend 1985: 50). As a consequence, I prefer to avoid these two names as lectotypes. Among the remaining two names, C. kirkii and C. glomerata , the first one was originally published by Hooker f. (1880: 31) who also first described the genus Centema Hooker f. (1880: 31) . Hooker f. (l.c.) also listed another species, Centema angolensis Hooker f. (1880: 31) , which was recently designated as the type of Centema by Hernández-Ledesma et al. (2015: 304) so superseding the previous typification by Phillips (1951: 277) who proposed C. kirkii as lectotype (the Phillips’ choice cannot be retained since C. kirkii does not currently belong to Centema ).

Taking the above into account, I think that Centemopsis glomerata is the best nomenclatural choice to represent the genus Centemopsis , and I here designated it as generitype (lecto-).

Lopriore (1900: 49) described Centema glomerata providing a detailed diagnosis, the provenance (“Huilla”), the collector (“Antunes”), and the date of collection (“ May 1895 ”). Lopriore (l.c.) also published an image (“Taf. 1H”) which is part of the original material for the name Centema glomerata . Since no specimens useful for the lectotypification purpose were found, I here designated the Lopriore’s image as the lectotype of the name Centema glomerata .
