Tristania(redirected from Tristenia)
a genus of evergreen trees and shrubs of the family Myrtaceae. The leaves are alternate and mostly oval or lanceolate. The flowers have a double perianth and numerous stamens. The fruit is a capsule.
There are more than 20 species (according to other data, as many as 50), distributed in Southeast Asia, Australia (Queensland), New Caledonia, and Fiji. Some species are cultivated as ornamentals. T. laurina is grown in the USSR on the Black Sea Coast of the Caucasus. A tree reaching 20 m in height, it has entire leaves (6–13 cm long) and small golden yellow flowers gathered into five- to seven-flowered axillary inflorescences. In severe winters T. laurina suffers from frosts. The species T. conferta, commonly known as the brisbane-box, is raised in hothouses.
