I am used to Banksia marginata being a shrub to small tree around top of escarpment bogs in the area, but not to seeing it growing as a shrub to around a metre high in dry forests. However, barring an undescribed species, this is all this specimen can be. The toothed juvenile foliage and truncate leaf tip fit that species, and the small inflorescence means it can't be B. canei (also a high altitude species). This site is at 260m elevation, on granite, with some localised outcropping, which is where the Banksias were growing. The area burnt in Jan 2020, but in this location only at low intensity so some banksias survived it. One that had been burnt was resprouting at the base (4th photo).
