- Leaves ovate, elliptical to oblong, narrowing abruptly to a rounded or cordate base and to an acutely, or sometimes obtusely, acumin-: ate tip; length from 2.2 to 4 cm.; width from 1.7 to 2.4 cm.; petiole not preserved; midrib stout near the base, gradually becoming slender toward the apex; 4 to 6 pairs of slender secondaries, sub-opposite to alternate, sub-parallel to irregularly spreading, the angle of divergence from the midrib varying from almost 90° near the base to as low as 35° toward the apex; secondaries more widely spaced along the midrib toward the apex, where they tend to branch at about half their length, the branches, as well as the lower secondaries, terminating in the marginal teeth; finer venation quite indistinct, forming an irregular network; margin rarely entire, usually 3 to 6 pairs of lobate teeth, attenuate or . only slightly produced into short spines; texture coriaceous as indicated by the convexity of the leaf and the faint preservation of the finer venation.
