Description

Swainsona monticola is a low growing, perennial plant and stems with short, slightly flattened hairs. The leaves are 5–10 cm (2.0–3.9 in) long with 11 to 25 narrowly egg-shaped, oblong or elliptic-shaped leaflets 2–15 mm (0.079–0.591 in) long, 3 mm (0.12 in) wide, rounded or notched at the apex and the lower surface with occasional hairs. The 3-15 pea-shaped flowers are borne on upright stems in a raceme, 4–7 mm (0.16–0.28 in) long, corolla purple with two small white spots on the standard petal and the pedicel 5 mm (0.20 in) long. Flowering occurs from October to February and the fruit is oblong-oval shaped, up to 1.5 cm (0.59 in) long, 8–15 mm (0.31–0.59 in) long and more or less smooth.[2][3][4]

Taxonomy and naming

Swainsona monticola was formally described 1864 by George Bentham from an unpublished description by Allan Cunningham and published in Flora Australiensis.[5][6]The specific epithet (monticola) is derived from the Latin mons, meaning "mountain" and cola, meaning "dweller", referring to the montane habitat.[7]

Distribution and habitat

Notched Swainson-pea grows at higher altitudes on woodland or rocky slopes in New South Wales and the Australian Capital Territory.[2][3]
