Kunzea rupestris, the rocky kunzea, is a rare Australian plant in the myrtle family. There are some 20 known populations, all just north of Sydney, including Ku-ring-gai Chase National Park and Marramarra National Park. Threats to this species include track maintenance, invasive weeds, removal of rocks and sand, fire management and the cut flower industry.[1]
Kunzea rupestris grows as a spreading clonal shrub, 0.5 to 2 metres tall. Foliage is dense with leaves 6 to 11 mm long,1.5 to 3 mm wide. The reverse lanceolate shaped leaves have a triangular shaped tip. New growth is noticeably villous. Mature leaves may be without hairs. White to cream flowers form in stalkless clusters in spring at the edge of branchlets. The sepals have a triangular shape, 1 to 1.5 mm long. Petals are 1 to 1.5 mm long. The hypanthium of the flower is also densely covered in small shaggy hairs.[2]
Distribution and habitat
Kunzea rupestris usually grows on rocky platforms.[3] It is known to occur between Lower Portland in the north and Ku-ring-gai Chase National Park to the south in central New South Wales. Often found in depressions or cracks in the rock with poor quality shallow soil, it is sometimes associated with moss. It grows at elevations between 50 metres and 300 metres above sea level. The habitat is exposed to full sunshine, regular drought, high temperatures, heavy rain and occasional frost and fire.
