Leptosema uniflorum

Leptosema uniflorum is a prostrate or low-growing shrub or subshrub that typically grows up to 2 m (6 ft 7 in) wide, its stems and branches compressed or flat cladodes 2–5 mm (0.079–0.197 in) wide. Its adult leaves are reduced to narrowly egg-shaped scales about 3 mm (0.12 in) long, but that fall off as they mature. The flowers are resupinate, arranged singly along the cladodes, each flower on a pedicel 8–14 mm (0.31–0.55 in) long. The sepals are leathery, 6–8 mm (0.24–0.31 in) long and there are ten stamens. The petals are dark red and mostly shorter than the sepals, the standard petal about 8 mm (0.31 in) long and 7 mm (0.28 in) broad, the wings about 9 mm (0.35 in) long and 3 mm (0.12 in) wide and the keel pouch-like, 10 mm (0.39 in) long and 4 mm (0.16 in) wide. The ovary has about 17 ovules. Flowering occurs from April to July, and the pods are spindle-shaped and beaked, 20–27 mm (0.79–1.06 in) long and 7–10 mm (0.28–0.39 in) wide containing a kidney-shaped, yellowish-brown seed about 3.5 mm (0.14 in) long.

Leptosema uniflorum grows in sand over sandstone or laterite in heath or woodland in Arnhem Land and offshore islands including Melville Island.
