Discussion:This species is related to C. turbinata D C . of Brazil, French Guiana, and Suriname, from which it differs in the leaf-blades completely glabrous beneath, glabrous stipules, fewer lateral nerves of the leaf-blades, larger broader leafblades more rounded at both ends, and relatively short petioles. From C. barbata it differs in the tomentulose shorter fruiting capsules and leaf-blades rounded to subcordate at base.
