Australia, an island continent isolated by oceans from the rest of the world, has stunning biodiversity of plants. In 1770, Captain Cook and Sir Joseph Banks, his botanist on board the Endeavor, were the first white men to land at "Botany Bay" (Cook's name), and discovered a plant with spikes of golden flowers appearing like ripe ears of corn or bronzed pinecones. Cook, a master navigator and labeler of newly discovered lands and seas, named Banksia after the 26-year-old botanist.

The flower spikes of Banksias are terminal and consist of thousands of individual flowers in pairs around a central woody cone. The brilliant golden-orange styles of River Banksia flare out with soft curved hooks from the woody axis. Sunbirds, with long beaks, can sip out the rich nectar contained deep within them. Old cones from years past perch on the branches, and the winged seeds embedded in the ovaries can remain on the cone indefinitely until the heat of a wildfire forces them open.

Along the southwestern and southeastern coastal areas of Australia are close to 76 species of Banksia with a great variety of leaves and growth habits. From prostrate ground growers, to shrubs, to trees with irregular trunks, Banksia are quite differentiated. A few species are also found in southern New Guinea. River Banksia is a small tree with long slender serrated leaves with pale undersides. The flowers are a magnificent red-gold.
