Abstract


A group of nine species -now included in Brassica— differ from all the other species in several characters, mainly in the stylar portion of their pistils always without seed primordia. Also in their branched subterranean stem (caudex) with several leaf rosettes, their leaves entire to deeply pinnatifid but never pinnatisect, their shallowly notched cotyledons and their flattened, elliptic or ovoid seed contour. It is suggested to include these species under the generic denomination Guenthera Andr, in Bess. New ñames for the species and subspecies are provided, as well as a determination key for the species.
