Description and Ethnobotany

Growth Form Slender woody vine, climbing with tendrils borne from flower-bearing branches, reaching up to 25m height with support. Typically spreading widely amongst tree crowns, but main plant usually difficult to spot, unless when flowering.
Foliage Its alternate, stalked leaves have thickly leathery blades that are usually oblong to lance-shaped, and 5–15 by 1.8–8 cm, with two spoon-shaped glands at either side of the base.
Flowers The plant is monoecious, producing only male or only female flowers on the branches. The former is produced in much larger proportion. Flowers of both sexes are yellow, tubular, less than 1 cm wide, and arranged in hanging clusters.
Fruits Its shiny red fruit is capsule-shaped, about 5 cm long, and splits along three lines from the apex to reveal 15–40 seeds each. Its seeds are blackish when mature, flat and round. Each seed is also surrounded in white fleshy pulp, and suspended by pink threads.
Habitat It grows on trees in forests and along forest edges. It occurs locally in Central Catchment areas, Nee Soon Swamp Forest, and Chestnut Area.
Associated Fauna Locally preferred host / food plant for Cethosia hypsea hypsina (Malay Lacewing Butterfly), which lays its eggs on undersides of leaves, and on stems or tendrils.
Cultivation Fast growing. Best propagated by seeds (which germinate easily) or by cuttings. Cut surfaces should be handled with caution, as Adenia genus (especially caudiciform types) is known to contain toxic sap, which is poisonous if ingested by vetebrates, and may cause skin irritation in sensitive individuals.
Etymology Genus epithet 'Adenia' derived from Aden, a small seaport near the Red Sea, from which the type species originated. Species epithet 'macrophylla' means 'big leaf', a reference to the plant's relatively large leaves.
