Leptosema bossiaeoides is a species of flowering plant in the family Fabaceae and is endemic to the Northern Territory. It is a straggling, low-growing or prostrate shrub with flat, winged stems and branches, leaves reduced to narrowly elliptic scales, pale yellowish-green flowers, and oval, beaked pods.
Description
Leptosema bossiaeoides is a straggling, low-growing or prostrate shrub with flat, winged, striated stems and branches up to 10 mm (0.39 in) wide. Its adult leaves are reduced to narrowly egg-shaped, channelled scales, 3–5 mm (0.12–0.20 in) long. The flowers are pale yellowish-green, and arranged in racemes of two to five flowers on a rachis up to 12 mm (0.47 in) long along the stems and branches, each flower on a pedicel 3–6 mm (0.12–0.24 in) long. The standard petal is 7–8 mm (0.28–0.31 in) long and about 3 mm (0.12 in) broad, the wings are awl-shaped, 8–9 mm (0.31–0.35 in) long and 1.5–2.0 mm (0.059–0.079 in) wide and the keel is elliptic, 9–10 mm (0.35–0.39 in) long. The ovary has about 4 ovules. Flowering occurs in most months, and the pods are oval, slightly inflated, about 7 mm (0.28 in) long and 4 mm (0.16 in) wide, including a beak about 2 mm (0.079 in) long.[2]
Taxonomy
Leptosema bossiaeoides was first formally described in 1837 by George Bentham in his Commentationes de Leguminosarum Generibus from specimens collected on Sim's Island by Allan Cunningham.[3][4]
