Sarcodum is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Faboideae, tribe Wisterieae.[2] Its three species are twining vines growing over shrubs, and are native from southeast mainland China to the Solomon Islands.[1]
Sarcodum species are twining vines that scramble over shrubs, growing up to 5–10 m (16–33 ft) high. The mature stems are reddish brown. The leaves have 8–44 leaflets arranged in pairs, plus a terminal leaflet. Individual leaflets may be up to 4.5 cm (1.8 in) long by 2.5 cm (1.0 in) wide. The inflorescences are composed of erect leafy axillary and terminal racemes 3–12 cm (1.2–4.7 in) long. Each flower is 6–19 mm (0.2–0.7 in) long, and has the typical shape of a member of the family Fabaceae. The pink or pinkish lilac standard petal is 10–13 mm (0.4–0.5 in) long by 6–8 mm (0.2–0.3 in) wide with a broad, dark yellow nectar guide. The wing petals are 8–13 mm (0.3–0.5 in) long by 3 mm (0.1 in) across, either much or slightly shorter than the keel petals, and with short basal claws. The keel petals are 13 mm (0.5 in) long by 4 mm (0.2 in) wide. Nine of the stamens are fused together, the tenth is free; all curve upwards at the apex. The seed pods are up to 5 cm (2.0 in) long, initially green, then black and hard when ripe, splitting to release the 4–10 seeds.[2]
