The species may be prostrate or erect in habit. The stiff, prickly and terete leaves are 30 mm (1.2 in) in length and 1 to 2 mm in diameter. The flowers appear in clusters at the ends of the branchlets. These have a 30 mm long perianth which is either pale pink and cream or deeper pink. Styles are about 40 mm (1.6 in) long, with or without hairs at the tips.^[3]

The species was first formally described in 1845 in Plantae Preissianae by Carl Meissner.^[1]

Subspecies

There are two recognised subspecies:

Both subspecies are highly susceptible to Phytophthora cinnamomi dieback.^[4]
