Cenarrhenes
Cenarrhenes is a monotypic genus in the family Proteaceae containing the single species Cenarrhenes nitida, known as the Port Arthur plum or native plum. Cenarrhenes nitida is an evergreen shrub to small tree endemic to the rainforests and scrublands of western Tasmania. It bears white flowers in late spring followed by the development of fleshy fruit.
Cenarrhenes nitida is a slow growing plant which requires a cool, moist, shady site with well composted soils and preferably good drainage. The seeds mature after the flesh has been removed and the stone allowed to dry. The seeds can be stored this way so long as they are kept in a well ventilated place. Germination is triggered by temperatures of roughly 20 °C (68 °F) after at least two months of cold stratification. C. nitida is often difficult to propagate and can be very slow growing if conditions are not right. They are best grown from seed as cuttings will remain green for considerable lengths of time without developing roots before turning brown.
Cenarrhenes nitida is endemic to southern and western Tasmania and some of its islands, growing to an altitude of 800 m (2,600 ft), and reaching the margins of the alpine zone. It occurs most often as an understory tree to small shrub in wet sclerophyll forests and rainforest with poor soils and occasionally in heath, button grass sedgeland and scrub. Offshore populations occur inland on South Bruny Island and in forested areas of the De Witt Islands, which closely resemble environments on mainland Tasmania.
