Macrozamia is a genus of around forty cycad species endemic to Australia. Many parts of the plant have been utilised for food and material, most of which is toxic if not processed correctly.[not in body]

Description

[edit]

A genus of cycads with partially submerged bole or tree, small to medium height, bearing a crown of palm-like fronds. The dioecious plants bear large cones, becoming even larger when ripening on the female, containing reproductive parts of great size.

Taxonomy

[edit]

The first description of the genus was published in 1842 by Friedrich Anton Wilhelm Miquel in his Monographia Cycadearum, without designating a type.[1]

The common name "burrawang",[2] originally referring to M. communis in the Daruk Australian Aboriginal language,[citation needed] is often used for all the species in the genus. Informal names published in state listing for the genus include 'rickets' (Bailey, 1931) in Queensland, a name also used in Western Australia for the symptoms of ingestion of species by cattle, and terms zamia, zamia palm, burrawang palm (Ross, 1989) and djeeri (Hopper, 2014) continued to be noted by New South Wales, QLD and W.A. authors in specific and generic usages.[3][4]
