Tendrils usually present on some twigs or branches.

Pods flat or slightly inflated, curved, about 10-20 x 2-3 cm. Seeds about 6-13, hard, flat, patelliform, about 8-10 mm diam. Cotyledons flat, about 9 x 8 mm, much longer than the 1 mm long radicle.

Seedlings

Cotyledons obovate, about 12-18 x 8-12 mm, fleshy, sessile. First pair of leaves pinnate with one pair of asymmetrical leaflets and a spur-like pendulous gland about 2-3 mm long attached between the leaflets. At the tenth leaf stage: leaves compound, leaflets +/- semi-orbicular, sessile, in pairs with a downward pointing gland or gland-like structure attached to the petiole between the leaflet pairs. Leaflet venation consists of three or four veins radiating from the base. Stipules broadly triangular, about 1 mm long.
