elva-climber

This species is characterized by its compound leaves with 1–2 pairs of pinnae and 1–3 pairs of leaflets, which are elliptic or narrowly obovate. The inflorescence is a puberulous spike, 11.5–30 cm long, bearing sessile to sub-sessile flowers. The fruit is a large craspedium, divided into one-seeded segments by transverse septa. Each segment is woody on the outside and chartaceous on the inside. The seeds are subcircular, laterally compressed, and reddish-brown. The species is distributed across Bangladesh, Borneo, China, Japan, and various Pacific islands. It was first published in 1914 by Merr., based on the earlier work of Linnaeus.
