Streblus banksii, commonly known as the large leaved milk tree, is endemic to New Zealand. This smallish tree has a spreading canopy and grows up to 12 m high with a short, stout trunk with smooth bark with corky spots. The leaves are 3.5-8.5cm long and 2-3.5cm wide with margins with rounded teeth. Green yellowish flowers appear between August and October, followed by red fleshy 65mm diameter berries. It grows in coastal and lowland forests as far south as the Marlborough Sounds, preferring deep, fertile soils. On offshore islands it seems more able to tolerate drier conditions and skeletal soils and may at times be found on steep cliff faces, rock ledges, or as stunted shrubs on cobble/boulder beaches.
