Etymology: Latin, montanus, pertaining to mountains, in reference to the occurrence on steep high ridges.

Historical notes:

Distinguishing features: Closely allied to M. communis, differing in the shorter and broader petioles with more reduced spine-like leaflets, and the somewhat glossier leaflets. Spines terminating sporophylls are also longer, most notably in female cones.

Distribution and habitat: New South Wales, Macleay to Manning catchments. Locally abundant in wet sclerophyll forests on ridges in the ranges or the eastern escarpment of the Northern Tablelands.

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