This species is strongly characterized by its elongated racemes forming 

 a terminal panicle, the younger parts of the inflorescences densely and 

 shortly subcinereous-pubescent, the older parts glabrous or nearly so, the 

 inequilateral, somewhat falcate calyx-tubes, the petals densely pubescent 

 on both surfaces, the peculiar staminodes, several with greatly thickened 

 bases and ail more or less connate, and the rather thin shortly-lobed, in 

 gênerai orbicular, cordate leaves which are glabrous, black and shining on 

 both surfaces when dry. It falls in Gagnepain's group I (with pubescent, 

 not glabrous, ovaries), but is not closely allied to any of the twenty-one 

 species placed by him in this assemblage.
