Banksia dentata

Banksia dentata.
Banksia dentata is a species of tree in the genus Banksia. It occurs in northern Australia, southern New Guinea and the Aru Islands. Growing as a gnarled tree up to 7 m (23 ft) high, it has leaves up to 22 cm (8.7 in) long with toothed margins. The cylindrical yellow flower spikes, up to 13 cm (5 in) high, appear between November and May, attracting honeyeaters, sunbirds, sugar gliders and insects. Flowers fall off the spikes, which swell and develop follicles containing up to two seeds each. Collected by Sir Joseph Banks in 1770, B. dentata is one of the four Banksia species published in 1782 as part of Carl Linnaeus the Younger's original description of Banksia. It is classified in Salicinae, a series, or group of species, from Australia's eastern states. Genetic studies show it to be an early offshoot within the group. It is found in savanna, associated with Pandanus and Melaleuca. After bushfires it regrows from its woody base, known as a lignotuber.
