Swainsona minutiflora

Swainsona minutiflora is a species of flowering plant in the family Fabaceae and is endemic to South Australia. It is a prostrate, herbaceous plant with imparipinnate leaves with 5 to 9 oblong or narrowly oblong leaflets with the narrower end towards the base, and racemes of 3 to 7 yellow or pinkish flowers.

Description
Swainsona minutiflora is a prostrate herb with several stems mostly up to 5–10 cm radiating from a tap root. Its leaves are imparipinnate, 22–55 mm long with 5 to 9 oblong or narrowly oblong leaflets 6–8 mm long and 2.0–2.5 mm wide on a hairy petiole. There is a tapering linear to narrowly triangular stipule 2–4 mm long at the base of the petiole. The flowers are arranged in racemes with 3 to 7 flowers on a peduncle mostly 40 mm long, each flower 4–5 mm long on a pedicel 1.5–2.0 mm long. The sepals are 2.0–2.5 mm long, the sepal lobes shorter than the tube. The petals are yellow, or pinkish, the standard petal about 4 mm long and wide, the wings 4.0–4.5 mm long, and the keel 4–5 mm long and 1.0–1.5 mm long and 1.0–1.5 mm deep. Flowering has been observed in August and October and the fruit is 15–23 mm long and 3 mm wide containing about 8 more or less square seeds about 1.5 mm long.

Taxonomy and naming
Swainsona minutiflora was first formally described in 1948 by Alma Theodora Lee in Contributions from the New South Wales National Herbarium, from specimens collected by Max Koch in Mount Lyndhurst in 1899. The specific epithet (minutiflora) means "very small flowers".
