Ventilago viminalis, commonly known as supplejack, vine tree or whip vine, [3] is a tree native to Northern and Central Australia from coastal regions of Queensland to the Northern Territory and Western Australia (with occurrences in New South Wales and South Australia). [4]
The plant begins life as a scrambler, using other trees, shrubs and even grasses for support. As it ages the stem becomes increasingly woody and the plant eventually develops a growth form more typical of a tree. [5] [6] The tree can reach 7 metres in height and often has several trunks with pendulous branch extremities. [3] The bark is dark and fissured. [3] The leaves have petioles and are green and lanceolate. [3] The flowers are small and greenish yellow. [3] Flowering season varies depending on rainfall.[ citation needed ] The fruits are indehiscent and have a single prominent longitudinal wing. [3]
It was first described by William Jackson Hooker in 1848. [1] [2] The species epithet, viminalis, is a Latin adjective describing the plant as having long flexible shoots suitable for basket work. [7] It is a member of the Rhamnaceae family. [1]
Australian Aborigines eat the gum from this tree. They scrape it off as it comes through, twisting it onto a stick. It can be chewed like chewing gum. The supplejack in Arrernte is called Atnyerampwe, and the gum is Ngwarle atnyerampwe.[ citation needed ] In the Kimberley Ventilago viminalis is commonly called the 'medicine tree'. Local people cut chunks out of the bark or roots to boil up and make an infusion to treat a variety of skin ailments as well as bruises and rheumatism. Trees with large telltale oval or oblong scars in the bark are often found in the local bush. [8]
The Walmajarri people of Paruku Indigenous Protected Area call this tree Walakarri, [9]
