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 dentata
"Banksia dentata" is one of four "Banksia" species collected by Sir Joseph Banks in 1770, and one of the four species published in 1782 as part of Carolus Linnaeus the Younger's original description of "Banksia". Within the genus, it is classified in the series "Salicinae", a group of species from Australia's eastern states. Genetic studies show it is a basal member (early offshoot) within the group. "Banksia dentata" is found in tropical grassland known as savanna, associated with "Pandanus" and "Melaleuca". It regenerates from bushfire by regrowing from its woody base, known as a lignotuber.
