Botanic information
Leaf: The semi-glossy dark green pinnate fronds of up to 2.7 m (8 ft) long and are upright to arching with a short smooth petiole and are strongly keeled. The linear leaflets are up to 150 mm (6 in) long and arranged in a single plane along the pale green rachis. there are up to 70 fronds arranged in a whorl at the top of the pinkish woolly crown.

Flower: The male cones are cylindrical up to 180mm (7¾in) long by 80mm (3⅛ in) diameter and number from 1 to 6. The spiny greenish ovoid female cones are up to 180mm (7 in) long and are pollinated by weevils. They appear in the woolly crown during summer.

Fruit: The fleshy red seeds are arranged in an ovoid cone that is up to 180 mm (7 in) tall with spiny tips. When ripe the cone disintegrates relisting the seeds that are eaten by Emu's who then distribute the seeds in their droppings. The seeds contain a starchy endosperm, which contain poisonous glycosides.

Note:
