Swainsona procumbens (common names - Broughton pea, swamp pea) is a plant in the pea family (Fabaceae) native to Australia and found in New South Wales, Victoria, Queensland and South Australia.[4]
Description
Swainsona procumbens is a spreading or ascending perennial with smooth or sparsely hair stems growing up to 50 cm high. The leaves are from 5 to 15 cm long, and pinnate with from 15 to 25 leaflets which have apices which are either notched or obtuse, and are 5–25 mm by 1–5 mm. The leaflet surfaces are without a covering or their lower surfaces may be densely covered in weak hairs. The leaves have stipules which are often toothed and from 2 to 7 mm long. The inflorescences are 2-12 flowered racemes, with flowers from 10–20 mm long. The corolla is mostly purple, and the apex of the keel coils into a complete circle. The style tip is inflexed. The pod is narrow and from 20 mm to 40 mm long and sometimes hairy.[4]
Habitat
It is found on heavy, frequently water logged soils.[4]
Taxonomy
It was first described as Cyclogyne procumbens by Ferdinand von Mueller in 1853,[1][5] but in 1859, Mueller reassigned it to the genus, Swainsona.[1][2]
