Taxonomy

The species was first described by Friedrich Anton Wilhelm Miquel.[3]

Description

The form of the species is a low-trunked cycad or upright tree, being highly variable. Leaves are dull and distinctly keeled, leaflets are medium or small. The species grows in low heath, without jarrah (Eucalyptus marginata), on sand.[3] Macrozamia fraseri is typical of cycads in being slow-growing, perennial, evergreen and dioecious. The trunk of old plants can be over a metre in height, with a surface burnt by bush fires of the past.

Macrozamia fraseri contains poisonous glycosides known as cycasins.
