Leaf blades about 8-17 x 7-14 cm, petioles about 1-2.5 cm long. Leaf blades 3-5-veined. 'Stipules' attached to the petioles and often extended to form simple (unbranched) tendrils.

Seedlings

Usually 1 or 2 cataphylls produced just outside the seed coat and 1 more further up the stem before the first true leaf. First true leaf ovate to elliptic, about 3 x 2 cm, apex acute, mucronate, base +/- obtuse, petiole about 8 mm long, base expanded into wings which embrace the stem. Leaf blade 3-veined with a fairly well developed intramarginal vein as well. Two narrow wings or ribs run down the stem from the base of each petiole. At the tenth leaf stage: leaf blade ovate-elliptic, apex apiculate, base obtuse. Midrib depressed on the upper surface. Leaf blade distinctly 3-veined perhaps even 5-veined. Intramarginal vein obvious often with a finer indistinct vein outside it and closer to the margin. Petiole thick and bent, the base sheathing the stem with membranous wings.
