- Leaves simple, varying in length from 5.5 to nearly 20 cm, and in width
from 3 to 14 cm; obovate, base slightly asymmetrical, cordate, rounded or pseudopeltate (with
two large rounded projections whose inner margins are convex); apex unknown; margin
entire. Venation brachidodromous; midvein stout, straight, raised, much thicker than
secondaries; secondary veins 16 to 18; alternate; the angles of divergence made with primary
vein at the base of leaf 130-150 degrees, at midpoint 65-85 degrees and at apex 50-60
degrees; secondaries straight; arched upward close to margin and giving off branches to
superadjacent secondary, with one of the branches stronger than the other; tertiaries
percurrent, oriented at right angles to secondary vein, forked or straight; quaternaries
orthogonal; areoles well developed; quadrangular, veinlets none; marginal ultimate venation
with loops.
