Description

Arrow-head Vine is a tall woody climber. The triangular leaves with broadly notched bases give the plant its common name, though leaf-shape varies through to oval. The leaves are thick, stiff, glossy, and are mostly 8 – 13 cm long. The leaf stalk is 5 – 12 cm long, with a swelling at each end, and a characteristic twist or angle at its junction with the stem. Male and female flowers are borne on separate plants, and are small and inconspicuous in long branched clusters. The fleshy fruits are produced in groups of three.

Distribution

North from the Richmond River in north-east NSW, where it is locally common in some parts of its range. Also recorded from a single location in south-east Queensland.

Habitat and ecology

Wetter subtropical rainforest, including littoral rainforest, on fertile, basalt-derived soils.

Threats

Clearing and fragmentation of habitat for development, agriculture, and roading.
Risk of local extinction because populations are small at some locations.
Grazing and trampling by domestic stock.
Fire.
Invasion of habitat by introduced weeds.
Accidental damage to plants when cutting introduced vines during bush regeneration.

Recovery strategies

Priority actions are the specific, practical things that must be done to recover a threatened species, population or ecological community. The Office of Environment and Heritage has identified 7 priority actions to help recover the Arrow-head Vine in New South Wales.

Activities to assist this species

Support local Landcare groups and bush regeneration teams.
Protect rainforest from fire.
Identify and protect Arrow-head Vine during regeneration work in areas of habitat.
Fence rainforest remnants to exclude grazing stock.
Control weeds in and near known habitat, taking particular care when other species of vine require cutting.
Protect areas of habitat from clearing or development.
Expand and connect remaining areas of habitat.
