- Diagnosis
- Leaves simple, widely elliptic, with cuneate decurrent base, 4—5 cm
long, 2—2,5 cm wide. Margin entire. Venation palmate-pinnate, brochidodromous, with
5—6 pairs of secondary veins. Basal secondary veins departing from midvein a short distance
above the leaf base at angle about 30—40°, straight or weakly curved, extending
about ⅔ distance to apex, looping with adjacent pair of secondary veins, bearing 5—7 short
branches, forming loops along the margin. Other pairs of secondary veins curved, weakly
undulating, diverge from midvein at angle about 45—55°, forming angular loops near the
margin. Infrabasal veins diverge from midvein an acute angle. Tertiary veins percurrent,
branching or reticulate.
