prickly ash, Orites excelsa(noun)
Australian tree having alternate simple leaves (when young they are pinnate with prickly toothed margins) and slender axillary spikes of white flowers
Orites excelsus is a rainforest tree of northern New South Wales and southeast Queensland. Known colloquially as the prickly ash, mountain silky oak or white beefwood, it is a member of the genus Orites within the family Proteaceae. Orites excelsus grows to 30 m high with grey-brown bark. The juvenile leaves are lobed, while adult leaves are simple – lanceolate, ovate or oblong, and are 4–18.5 cm long by 1.5–4.5 cm wide. New growth is covered in rusty hairs, but the leaves become smooth, glossy green above and grey or white below. Appearing in winter and spring, the inflorescences are axillary and measure 5 to 11 cm in length, and are composed of white fragrant flowers. The botanist Robert Brown described Orites excelsa in 1830, after it was collected by Charles Fraser near the Hastings River in 1818. Common names include mountain silky oak, southern silky oak, prickly ash, and white beefwood. The species name has been revised from excelsa to excelsus. Frederick Manson Bailey described Orites fragrans from Mounts Bellenden-Ker and Bartle Frere which turned out to be this species.
