Leaflets sparsely toothed, the tooth apices pungent to slightly rounded; bases acute and asymmetrical, tapering smoothly to a narrow, lateral, decurrent insertion on the rachis. Venation parallel, dense, and dichotomizing with no midvein. Adaxial epidermal cells arranged in elongate rows that parallel venation, the ends of the rows asymmetrically tapering to a point, the long axes of the cells oriented markedly obliquely to the direction of venation and with thicker walls at row boundaries than between rows.
