It is a prostrate perennial herb, covered in long shaggy haris and growing from 2 cm to 10 cm high. The leaves occur in pairs, and have leaflets in 7 - 10 pairs. The fruits have many spines, which are from 4 to 8 mm long. It grows on sandy soils and its yellow flowers can be seen from February to November.[1]
It was first described in 1849 by Robert Brown, from a specimen collected on the "west coast of Australia, or on some of its islands, in the Voyage of the Beagle."[6][7] There are no synonyms.[8]
