The leaf anatomy of three species of Finschia included in the subtribe Hakeinae (Proteaceae) is described.The stem-node-leaf continuum is described in F. chloroxantha Diels and F. rufa Warb.. Within the genus, features of the leaf epidermis make it possible to distinguish species and are consistent with synonymy between F. rufa and F. carrii (Sleumer) C.T.White.Anatomical characteristics are compared with those of Grevillea and Hakea and similarities that might support relationships are discussed.
