- Diagnosis
- Leaves large, simple, probably trilobate, symmetric or
slightly asymmetric, with dentate margin. Leaf lamina
transversely-elliptic, base broadly cuneate and slightly decurrent,
apex obtuse. Leaf margin dentate, teeth simple, rare, medium in
size, triangular, with acute apices, sinuses between them round.
Venation palmately-pinnate craspedodromous. Midvein stout
and straight. Two lateral basal veins straight and slightly curving
upwards, terminating at the lateral lobe apices. Six or seven
abaxial and one or two adaxial secondaries emerge from each
lateral basal vein. Three pairs of simple opposite craspedodromous
suprabasal secondary veins and one pair of thin and short
infrabasal secondary vein emerge from a midvein. Tertiary veins
prominent, slightly curved, percurrent or ramified-percurrent,
almost perpendicular to the midvein and emerging from the
secondary veins at an acute angle.
