Macrozamia mountperriensis

Macrozamia mountperriensis F.M. Bailey, "Syn. Queensland Fl., suppl. 1, 50" (1886).
"TYPE: Australia, Queensland, adjacent to Schuh Lookout, c. 3 km west of Mt Perry beside road to Monto, D.L. Jones 6340 & B.E. Jones, 29 August 1990 (neo: CBG; isoneo: BRI, CBG, NSW; fide P.I. Forster & D.L. Jones, Telopea 5(1): 289, 1992)."


Etymology: In reference to the occurrence in the Mount Perry district.

Historical notes:

Distinguishing features: A member of the M. miquelii complex, recognisable by its small stature, light green leaves with none of the lowermost leaflets reduced to spines, and the small size of the male and female cones and the seeds. It differs from the very close M. longispina in its somewhat more robust habit with longer leaves, more leaflets that are broader, and slightly larger male and female cones with smaller spines on the sporophylls.

Distribution and habitat: Queensland, known from several stands around Mt Perry, ranging from grassy eucalypt forests or woodlands to Araucarian rainforest.

Conservation status: Not considered to be at risk (IUCN Red List category LR,lc).
