Taxonomy
Summarize
Perspective
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]
