Macrozamia communis L.A.S.Johnson, Proc. Linn. Soc. New South Wales 84: 98 1959. (Syn: Encephalartos spiralis var. major Miq.; Macrozamia amabilis W.Bull; Macrozamia eximia W.Bull; Macrozamia hillii W.Bull; Macrozamia pulchra W.Bull; Macrozamia spiralis var. eximia (W.Bull) Regel; Macrozamia spiralis var. fraseri Regel; Macrozamia spiralis var. hillii (W.Bull) Regel; Macrozamia tridentata f. hillii (W.Bull) J.Schust.; Macrozamia tridentata var. pungens J.Schust.; Macrozamia tridentata f. vavilovii J.Schust.);
The plants grow in open forests.
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.
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.
