A beautiful genus of about seven species of evergreen shrubs, natives of Australia and Tasmania. The showy flowers are borne singly or two to three together; calyx cup-shaped, truncate or toothed; petals four, more or less united into a bell-shaped or cylindrical tube; stamens eight. Fruit dry, splitting into four dehiscent parts. Forms of the very variable C. reflexa (speciosa) were once popular as pot plants for the cool greenhouse, all very tender. The species described here are not the showiest of the genus, but are perhaps hardier than the others.
