Banksia burdettii (Banksia burdettii)

Description

Banksia burdettii grows as an evergreen shrub to a height of 4 metres (13 ft). The new growth is hairy, though longer stems are smooth. The sturdy, serrated grey green leaves are 10–16 centimetres (3.9–6.3 in) long and 1.5–2.5 centimetres (0.59–0.98 in) wide with a narrow oblong or wedge-shape and a truncate tip. The toothed margins are slightly downcurved.Burdett's banksia has 6–10 centimetres (2.4–3.9 in) cm high flower spikes, known as inflorescences, that prominently displayed on the ends of stems, appearing between the months of January and May, peaking over February and March. A 1988 field study in Watheroo National Park revealed that each flower spike has 972 ± 130 florets.The individual flowers are hairy and white on the outside and orange within, the flower spikes turning from white to orange as anthesis proceeds up the spike. Old flower spikes fade to grey over time, and develop up to 20 follicles (seed pods) each. Each follicle contains two seeds, though around 36% of seeds are nonviable. Almost all follicles remain closed until opened by bushfire.
