Billardiera uniflora

Billardiera uniflora is glabrous, woody climber with narrowly elliptic leaves, 40–52 mm (1.6–2.0 in) long and 4–6 mm (0.16–0.24 in) wide with wavy edges. The flowers are arranged singly or in pairs on a thin, down-curved, more or less glabrous peduncle 10–14 mm (0.39–0.55 in) long. The sepals are egg-shaped, 4–5 mm (0.16–0.20 in) long and about 1.5 mm (0.059 in) wide. The petals are yellow and turn pinkish-red as they age, 17–19 mm (0.67–0.75 in) long and 2.0–2.8 mm (0.079–0.110 in) wide. Flowering occurs in August and September and the mature fruit is a glabrous oblong berry 30–40 mm (1.2–1.6 in) long containing brown seeds 2–3 mm (0.079–0.118 in) long.

This species grows in mallee scrub and coastal heath on limestone and is endemic to the Mount Lofty and Port Lincoln areas and Kangaroo Island in south-eastern South Australia.
