To what family does Kleinia and Rudbeckia belong to?
Rudbeckia Rudbeckia is a plant genus in the sunflower family. The species are commonly called coneflowers and black-eyed-susans; all are native to North America and many species are cultivated in gardens for their showy yellow or gold flower heads.
Grewia The large flowering plant genus Grewia is today placed by most authors in the mallow family Malvaceae, in the expanded sense as proposed by in the APG. Formerly, it was placed in either the linden family (Tiliaceae) or the Sparrmanniaceae. However, these were both not monophyletic with respect to other Malvales - as already indicated by the uncertainties surrounding placement of "Grewia" and similar genera - and have thus been merged into the Malvaceae. Together with the bulk of the former Sparrmanniaceae, "Grewia" is in the subfamily Grewioideae and therein the tribe Grewieae, of which it is the type genus.
