White oak (Grevillea baileyana)
Description
Grevillea baileyana, commonly known as white oak, is a tree of the family Proteaceae that is native to the rainforests of north-east Queensland in Australia and Papua New Guinea. In its native rainforest habitat, Grevillea baileyana can grow as a tree to 30 m (100 ft) high. Its hard scaly bark is grey. Both adult and juvenile leaves are 6–30 cm (5.2–12 in) long; the juvenile leaves are pinnatifid, that is, divided into five to nine lanceolate (spear-shaped) lobes on each side of the leaf, while the adult leaves are a simple spear-shape (lanceolate) and 1–6 or rarely 10 cm (0.4–4 in) wide. They are a shiny smooth green above with a conspicuous midvein, and covered in rust-coloured fur below. The flowerheads appear in spring and summer (August to December) and are greenish in bud and white on maturity.
