Rhus angustifolia, the willow karee or smalblaar, is a small, bushy, evergreen tree which is confined to the South Western Cape in South Africa. The multi-stemmed willow karee bush grows to a height of about 4 meters. It has trifoliate leaves with dark green surfaces and grey furry undersides. Its flowers are small and cream coloured. The female plants produce clumps of tiny berries. In the Western Cape, dense thickets of this bush can be seen growing alongside rivers and roads.
