Oldenburgia grandis (SA Tree No. 737), donkey’s ears or in Afrikaans the Suurbergkussingbos, is a small tree (SA Tree List No. 737) or sometimes a large shrub. It often has a gnarled appearance with thick dark corky bark. The plant is sometimes thought to resemble the suikerbos, a name commonly associated with several plants in the Protea genus; but it really belongs in the daisy family (Coates Palgrave, 2002).

The distribution area is inland from Port Elizabeth in the Suurberg to Grahamstown. It will occasionally exceed 5 m in height.
