Leptosema chapmanii

Leptosema chapmanii is a shrub with many stems that reach to up to 40 cm (16 in) high, and flattened branchlets 1.5–5 mm (0.059–0.197 in) wide. Its leaves are reduced to dark red, triangular scales 1.5–3 mm (0.059–0.118 in) long. The flowers are densely packed, resupinate, and borne in densely packed rosettes at the base of the plant, each flower on a pedicel 2–8 mm (0.079–0.315 in) long on a rhachis up to 30 mm (1.2 in) long with egg-shaped bracts about 1.5–2 mm (0.059–0.079 in) long and narrowly egg-shaped bracteoles. The sepals are pink and united for half their length, so that the flower gapes. The petals are deep pink, about the same length as the sepals, the standard petal 4–10 mm (0.16–0.39 in) long, the wings triangular, 4–10 mm (0.16–0.39 in) long and 1.0–1.5 mm (0.039–0.059 in) wide and the keel similar to the wings. There are five to eight stamens and the ovary is more or less sessile with 12 to 18 ovules. The pods are very broadly oval, 6–10 mm (0.24–0.39 in) long and 4.5–6 mm (0.18–0.24 in) wide including a beak 1–4 mm (0.039–0.157 in) long, containing a single kidney-shaped seed.

This species of Leptosema grows in heath or shrubland on sandy or gravelly soil in the North Kennedy, Leichhardt and Mitchell districts of Central Queensland.
