This upland rainforest grape vine has very distinctive characters. The compound leaves with three leaflets (ie trifoliate leaf) and in particular on the underside of each leaflet there are domatia (cavernous-like structures) that is found at the midrib-secondary vein junctions. The specific epithet ‘sterculiifolia‘ alludes to the resemblance of the leaves to that of Sterculia, although I must say I do not see any such resemblance. The common names of of this grape vine are many, including: Pomegranate Vine, Long-leaf Water Vine, Long-leaved Grape and Yaroong, all of which I find are equally poorly descriptive. I wonder though if the fruits taste like pomegranates. This species is probably awaiting a name change once Betsy Jackes finishes her Flora of Australia taxonomic treatment of the grapevine family.
