Abstract

The new genus Guianodendron Schütz Rodrigues & A. M. G. Azevedo (Leguminosae, Papilionoideae, Sophoreae) from Guyana and the Brazilian state of Amazonas is described and illustrated, and a new combination, Guianodendron praeclarum (Sandwith) Schütz Rodrigues & A. M. G. Azevedo, is made. The genus is characterized by a radial corolla with auriculate petals; five stamens; reduced ovule number; a straight hypanthium; indehiscent, flattened, and sutural-winged fruits; persistent bracts and bracteoles; leaflets with a papillate abaxial epidermis; and ovate to ovate-elliptic markedly striate stipules.
