Banksia spinulosa
The hairpin banksia ("Banksia spinulosa") is a species of woody shrub, of the genus "Banksia" in the family Proteaceae, native to eastern Australia. Widely distributed, it is found as an understorey plant in open dry forest or heathland from Victoria to northern Queensland, generally on sandstone though sometimes also clay soils. It generally grows as a small shrub to in height, though can be a straggly tree to . It has long narrow leaves with inflorescences which can vary considerably in coloration; while the spikes are gold or less commonly yellowish, the emergent styles may be a wide range of colours – from black, purple, red, orange or yellow.
Banksia montana
"Banksia montana" is killed by bushfire and regenerates from seed. Taking up to nine years to flower and fruit from seed, it is thought to require bushfires at intervals of 18 years for best recovery. However, two fires in quick succession in its native habitat killed many plants with little recruitment. The species is also highly sensitive to dieback ("Phytophthora cinnamomi"), which has infested three of four extant populations.
