Swainsona oligophylla

Swainsona oligophylla is a prostrate or occasionally ascending annual perennial plant, that typically grows to a height of about and has many stems. The leaves are imparipinnate, mostly long with 5 to 7 egg-shaped leaflets with the narrower end towards the base, mostly long and wide with stipules about long at the base of the petioles. The flowers are purple, arranged in racemes of 3 to 7, long, on a peduncle up to long. The sepals are joined at the base to form a tube about long, with lobes 3 or 4 times longer than the tube. The standard petal is long, the wings about long and the keel about long and deep. Flowering usually occurs from August to October, and the fruit is a cylindrical pod long on a stalk about long, with the remains of the strongly curved style about long. ==Taxonomy and naming==

Swainsona oligophylla was first formally described in 1864 by George Bentham in Flora Australiensis from an unpublished description by Ferdinand von Mueller. The specific epithet (oligophylla) means "few-leaved". ==Distribution==
