Macrozamia communis (Cultivated- USA)

Macrozamia communis is an Australian cycad found on the east coast of New South Wales.
The common name for the species is burrawang, a word derived from the Daruk Australian Aboriginal language; this name is also often applied to other species of Macrozamia.
The plants grow in open forests.^[3]
Seed cones are formed after fire. Male and female seed cones are on separate plants and the large female seeds are ripe when red or yellow.^[3]
The seeds of the burrawang are a good source of starch but are poisonous to eat unless treated. The Cadigal people pounded and soaked the seeds in water for a week, changing the water daily. The pulp was then made into cakes and roasted over hot embers.^[4]
