Jeruju
Acanthus volubilis
Family Acanthaceae


Southeast Asia and New Guinea. Locally, in various northern sites. Semi-erect to climbing herb with thin, wiry, spineless, dark-green stems; leaf blades with smooth margins or slightly lobed, mostly without spines; flowers in neatly organised spikes at branch tips; petals white, turning brown when older; fruits are very rare. Found in tidal mud among grasses.

From Malay folklore, powdered seeds are taken with water as a blood cleansing medicine and against ulcers. Vulnerable.
