A genus of very pretty and interesting greenhouse Heath-like shrubs, natives of Australia. Flowers small; bracteoles two under each flower; they are either free or joined together at the base, some-times in the form of an operculum. Leaves scattered, crowded, opposite, full of dots, axillary, solitary, almost sessile. They grow well in a mixture of loam, peat, and sand, with good drainage and firm potting. Cuttings, made from young shoots, will root in April or May, if placed in sand, under a bell glass, in a cool house. C. ericoides (Heath-like). A synonym of C. tetragona. C. glabra (glabrous). A synonym of C. tetragona.
