The slender stalk-like region between the ovary and the campanulate calyx-tube is usually rather more pronounced than in the specimen (Angus 708) figured by Exell and Stace (loc. cit.). The fruit in that plate is of subsp. australis.
Deciduous scandent shrub up to 2–4 m. high or more rarely a small tree up to 5 m.; bark light-grey to blackish; branchlets reddish-brown, slender, at first minutely pubescent, glabrescent.
Fruit reddish-brown, up to 1·3 x 1·3 cm., subcircular to broadly obovate in outline, glabrous, apical peg less than 0–5 mm. long, wings up to 5 mm. broad, stipe 0·5–1·5 mm. long.
Lower receptacle with a part containing the ovary c. 1 mm. long produced into a more slender portion 0·5–1 mm. long on which the calyx-tube is borne somewhat obliquely.
Inflorescences of axillary spikes 2·5–9 cm. long; rhachis slender, pubescent or glabrous; bracts 0·8–2 mm. long, somewhat persistent.

Cotyledons (known only in subsp. australis) 10–12 x 15–17 mm. with petioles 2–3 mm. long.
