Etymology
Banksia named after Sir Joseph Banks (1743-1820), a 19th century botanist and president of the Royal Society who travelled with Captain Cook on his first voyage to 'New Holland' in 1770. Marginata from the Latin 'marginatus' meaning bordered, referring to the recurved leaf margins on some forms.
Distribution and status
Found in the southern part of South Australia, growing on sandy to clay soils in sclerophyllous heath, woodlands and forest. Also found in New South Wales, Victoria and Tasmania. Native. Common in South Australia. Common in the other states.

Plant description
Tall shrub or small tree to 5 m tall. Leaves green with a square tip, smooth on the top side and white and hairy on the underside. Young leaves hairy all over with small serrations. Flowers are yellow in a large cylindrical cluster. Flowering throughout the year. Fruits are large, hairy, woody cone with numerous valves. Seeds are flat, dark brown, pyramid shaped seeds to 10 mm long with a large papery wing at one end. Seed embryo type is investing.
Seed collection and propagation
Collect seeds between January and December. Collect mature cones with obvious un-open valves. These will contain viable seeds. Mature cones can be hard to fine as very few are produced. Place cones in a tray and leave to dry until the valves open. Cones can be placed in the oven at low temperatures to achieve the same result. Place the dried cones in a bucket and shake to dislodge the seeds from the valves. Separate the seeds from the cone and store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. Seed viability is usually high however, seed development in some area is very low. Seeds are non-dormant, viable seed should germinate readily without pre-treatment.
