Banksia elderiana
The Swordfish Banksia (''Banksia elderiana''), commonly known as the swordfish banksia or palm banksia, is a species of shrub in the plant genus ''Banksia''. It occurs in two disjunct areas in the Goldfields-Esperance region of Western Australia. One population extends over a large area from west of Kalgoorlie south to Ravensthorpe, with another population in the Great Victoria Desert north of the Queen Victoria Spring.
Seeds do not require any treatment, and take 31 to 42 days to germinate.
==Description==
''Banksia elderiana'' grows as a tangled and bushy shrub to 3 m (10 ft) in height, with new growth covered densely with brown fur. The stiff linear narrow leaves are very long and curled, measuring 15 to 40 cm (6–16 in) long and 1.2–2 cm (0.5-0.8 in) wide. The leaf margins are serrated, with many teeth measuring 0.3 to 0.5 cm each. Flowering typically occurs between January and March, but may continue into winter. The all-yellow inflorescences hang down from branchlets and measure 4–6 cm (1.6–2.4 in) in length. The inflorescences turn grey as they age, and the old flowers remain as up to 30 large woody follicles develop. Oval in shape, and covered with fine hair, they can reach 2.5 cm long 1.4 cm high, and 1.8 cm wide.
