Scientific name: Bossiaea oligosperma
Conservation status in NSW: Vulnerable
Commonwealth status: Vulnerable
Profile last updated: 16 Aug 2018


The Few-seeded Bossiaea is an erect shrub to 2 metres high. The small, almost circular, bright-green leaves are between 2.5 - 5 mm long. The 8 - 11 mm long pea flowers appear in late spring. The wings (upper, larger petal) are bright yellow with some red markings, the keel (lower, fused, smaller petals) is dark red. The pod is elliptical and up to 17mm long. The bark of mature plants is distinctively flaky. Few-seeded Bossiaea may be confused with Bossiaea obcordata, a common pea in eastern NSW, but B. obcordata has spiny branches and is generally a smaller plant.


The Few-seeded Bossiaea is known from two disjunct areas - the lower Blue Mountains in the Warragamba area (Wollondilly, Allum, Tonalli River catchments) and the Windellama area in Goulburn Mulwaree Shire, where it is locally abundant. A 1960s record for the Araluen valley south of Braidwood is credible but has not been relocated.

Habitat and ecology

  • Occurs on stony slopes or ridges on sandstone in the Yerranderie area.
  • Occurs in low woodland on loamy soil in the Windellama area.
  • Nothing is known about its ecology but it probably has hard-coated seeds that respond well to fire and soil disturbance.
