Endosamara racemosa

Endosamara racemosa is a robust twining woody vine. The young stems are green and covered with soft hairs (pubescent); the mature stems are pale brown and hairless. The leaves are evergreen and generally have 6–12 paired leaflets plus a terminal leaflet. The leaflets are 5–13 cm (2.0–5.1 in) long by 2–7 cm (0.8–2.8 in) wide. The robust inflorescence is a many-flowered terminal panicle, 20–50 cm (8–20 in) long. The individual flowers are 13–16 mm (0.5–0.6 in) long and have the general shape of members of the subfamily Faboideae. The standard petal is 10–15 mm (0.4–0.6 in) long by 12–15 mm (0.5–0.6 in) wide. The inner surface is pink or pinkish purple, rarely white, with a dark greenish yellow nectar guide. The wing petals are slightly longer than the keel at 12–13 mm (0.5–0.5 in) long by 3–5 mm (0.1–0.2 in) wide, with short basal claws. The keel petals are 10–12 mm (0.4–0.5 in) long by 4–6 mm (0.2–0.2 in) wide, united into a cup. Nine of the stamens are fused together, the other is free; all curve upwards at the apex. The flattened seed pods are 8–25 cm (3.1–9.8 in) long by 1–2 cm (0.4–0.8 in) wide, black when dry, and have 4–5 seeds. A unique feature of the genus Endosamara within the tribe Wisterieae is that the pods split into one-seeded segments before releasing the seeds. …

Endosamara racemosa is found from South India to the Philippines, being native to Assam, Bangladesh, India, Laos, Malaya, Myanmar, the Philippines, Thailand and Vietnam.
