The species may be prostrate or erect in habit. The stiff, prickly and terete leaves are 30 mm 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 long, with or without hairs at the tips.[3]

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

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