- Diagnosis
- Leaf large, simple, trilobate, broadly triangular,
entire-margined. Leaf base deeply cordate,
apex narrow, round. Two large lateral lobes, broad,
probably round, situated in the lower part of the leaf;
sinuses between these and the apical part of the leaf
broad, shallow, round. Venation palmate brochidodromous.
Midvein straight, 3 pairs of lateral basal
veins emerging from the leaf base and running to the
lateral lobe, the uppermost pair being the most developed.
Basal veins forking up to three times, forming
loops along the leaf margin. 3-4 suprabasal secondary
veins brochidodromous, obliquely emerging from the
midvein, forking once and forming loops along the
leaf margin. Tertiary veins percurrent to orthogonal reticulate,
forming loops along the leaf margin.
