Macrozamia communis

Macrozamia communis L.A.S. Johnson, Proc. Linn. Soc. New South Wales 64(1): 98 (1959).
"TYPE: Australia, New South Wales, about three miles west of Mossy Point, near Mogo, J.W. Vickery NSW43071, Apr 1958 (holo NSW)."[NSW]

Etymology: Latin, communis, common or occurring in abundance, from the dense stands frequently seen in the wild.

Historical notes:

Distinguishing features: M. communis is distinguished by the dull, dark green leaves with thick, hypostomatic leaflets and more or less terete petioles with few reduced spine-like leaflets, and the large male and female cones with long and broad spines terminating the sporophylls.

Distribution and habitat: New South Wales, from Taree to Bega, strictly near-coastal in the north of the range but extending to the foothills of coastal ranges in the south. Locally abundant in wet to dry sclerophyll forests, mostly on old beach sands but also on shallow sandy or stony soils on ridges.

Conservation status: Not considered to be at risk.
