- Diagnosis
- Leaf compound, with three or four leaflets; most commonly three leaflets closely arranged on the distal portion of the rachis, occasionally with one leaflet attached at some distance proximally on rachis; rachis thin. Leaflet lorate, always curved abaxially; apex attenuate; base normal acute; lateral leaflets sessile and terminal leaflets petiolulate; margin entire, usually revolute. Primary venation pinnate; primary vein stout; course straight (medial leaflet) or recurved (lateral leaflets). Secondary venation brochidodromous; secondary veins thin relative to primary vein; opposite to subopposite, decurrent; angle of divergence acute, joining superadjacent secondary veins to form a loop enclosing an intercostal area, with two series of loops (tertiary and quaternary in order) in excostal region; exmedial branches of secondary veins common, forming tertiary veins. Intersecondary veins common. Tertiary vein moderate; orthogonal reticulate but tending to be percurrent, retroflexed. Quaternary veins random reticulate, forming incompletely closed meshes. Veinlets simple, linear.
