Description
Homoranthus decumbens is a low shrub growing to 60cm high and spreading up to 2m across the ground. The leaves are cylindrical, measuring 6-12mm long by about 0.4mm in diameter and are arranged opposite each other in pairs along the branches. The leaves vary in colour from a pale bluish tint to reddish-brown, and smell strongly of menthol when crushed.
The tiny yellow-green flowers are borne singly along the branches from near the base of the leaves. Each flower consists of a ribbed cylindrical tube 4-5mm long, with five petals, five sepals (petal-like structures surrounding the petals), and a style (filamentous, reproductive structure) protruding from within the flower. The sepals and petals are up to 1.5mm long. The style is 5-6mm long. (Craven & Jones 1991; Wang 1995; DEWHA 2008)
