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 scabrella
"Banksia scabrella" is found in two disjunct areas of scattered populations; the first discovered being southeast of the small town of Walkaway south of Geraldton, while a more populous cluster is found southeast of Mount Adams in Western Australia. The average annual rainfall over its range is around 450 mm (18 in). It has been placed on the Declared Rare and Priority Flora List, where it is classified as a "Priority Four – Rare" taxon; although it is rare, it is not currently threatened by any identifiable factors. These taxa require monitoring every 5 to 10 years. Many stands are populous, and number over 100 plants. However, over half the known population of "B. scabrella" is found on road verges. Found in deep pale yellow or white sand in kwongan scrubland and heathland, "B. scabrella" grows on flat areas or gentle slopes and is found in association with "B. leptophylla" and a dwarf form of "B. attenuata".
