Macrozamia spiralis

A small, trunkless cycad of the dry sclerophyll forests of the Sydney Basin and central New South Wales, with spirally twisted fronds up to about a metre long. It is slow, takes 10–20 years to cone, and resprouts after bushfire; in cultivation it wants a mild, bright position and a lean, sharply drained soil.
