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 densa
Banksia densa is a shrub endemic to Western Australia. It was known as Dryandra conferta until 2007, when all "Dryandra" species were transferred to "Banksia" by Austin Mast and Kevin Thiele. As there was already a plant named "Banksia conferta" (Glasshouse Banksia), Mast and Thiele were forced to choose a new specific epithet; their choice, "densa", is from the Latin "densus" ("thick, close, compact"), in reference to the way the leaves are densely crowded around the inflorescences.
