- Leaves compound, ternate. Petiole thick, about 2,5 mm in diameter. Petiolules
thick, short, about 1,5—2 mm long and 1,5 mm wide. Leafl ets widely elliptic, 2,5 cm
long and 1,6—1,8 cm wide, with acute apex and cuneate decurrent or rounded, slightly asymmetrical
base. Margin entire. Lateral leafl ets diverging from the petiole at an angle about 45—
50°. Venation pinnate, brochidodromous, with 5 pairs of curved, weakly undulating secondary
veins. Midvein straight, prominent. Secondary veins alternate, departing from midvein at
angle about 45—60°, at unequal distance one from another. Veins in the lower part of lamina
