Gouania australiana

Gouania australiana is a species of plant in the family Rhamnaceae, first described in 1864. It is native to the Wet Tropics bioregion of Queensland, Australia, and has a conservation status of least concern.

Description

Gouania australiana is a vine with a stem diameter up to 6 cm (2.4 in), which climbs by the use of tendrils growing from the leaf axils or at the ends of the branches. All parts of the plant have a dense covering of fine hairs. The leaves are almost circular in shape, growing up to 12 cm (4.7 in) long and 10 cm (3.9 in) wide, with a cordate base and an acuminate (shorty pointed) tip. The margins of the leaf blade are finely toothed, more so towards the tip.[3][4][5]

The inflorescence is much-branched and consists of a number of spikes; they are clustered at the ends of the branches. Flowers are reported to have a pleasant fragrance,[3] and are about 3 mm (0.12 in) diameter. Both the calyx and petals are white.[4][5]

The fruit is a cluster of three pale brown samaras about 5 mm (0.20 in) wide and long, each with one seed about 1 mm (0.04 in) long.[5]

Phenology

Flowering occurs between June and October, fruit occur between September and January.[5]

Distribution and habitat

It is endemic to the Wet Tropics area of Queensland and grows in lowland rainforest between the Daintree River in the north to Tully in the south.[4][5] The altitudinal range is from near sea level to about 300 m (980 ft).[3]

Conservation

This species is listed as least concern under the Queensland Government's Nature Conservation Act.[6] As of 12 June 2026, it has not been assessed by the International Union for Conservation of Nature (IUCN).
