Jagera pseudorhus (Sapindaceae)

This is the well-known foambark tree famed for the saponin foam that forms on the bark after heavy rain. It is usually found in lowland areas in coastal rain forest but can also be seen in upland rain forest. The widespread variety is Jagera pseudorhus var. pseudorhus (featured here). Another variety J. pseudorhus var. integerrima has less jagged leaflets and is endemic to the Atherton Tableland and surrounding mountainous areas.

Jagera pseudorhus

An extremely ornamental tree with a slight resemblance to the famous Neem tree (Azadiracta indica), as a result of their pinnate jagged leaves (in var. pseudorhus). Flowers develop terminally on branches and trees are very showy when in flower. The hairy capsule are a pleasure to espy, developing from a beautiful violet pink to a brown colour when mature.

Indigenous Australians supposedly used the foam from crushed bark or leaves to de-oxygenate the water of waterway pools, thereby temporarily suffocating fish for an easy catch.

About David Tng

I am David Tng, a hedonistic botanizer who pursues plants with a fervour. I chase the opportunity to delve into various aspects of the study of plants. I have spent untold hours staring at mosses and allied plants, taking picture of pollen, culturing orchids in clean cabinets, counting tree rings, monitoring plant flowering times, etc. I am currently engrossed in the study of plant ecology (a grand excuse to see 'anything I can). Sometimes I think of myself as a shadow taxonomist, a sentimental ecologist, and a spiritual environmentalist - but at the very root of it all, a "plant whisperer"!
