Macrozamia lucida

Macrozamia lucida L.A.S. Johnson, Proc. Linn. Soc. New South Wales 84: 102 (1959).
"TYPE: Australia, Queensland, southern side of Ngungun, abt. 400 ft. alt., Glass House Mountains, L.A.S. Johnson NSW 40668, 13 Jun 1951 (holo NSW)."[NSW]


Etymology: Latin, lucidus, shining, from the highly glossy leaves.

Historical notes:

Distinguishing features: Distinguished by the broad, very glossy and dark green leaves with long spine-free petioles and broad, non-pungent leaflets with large white callous bases.

Distribution and habitat: Southern Queensland, from around Brisbane north to Nambour. Scattered and sporadic in coastal wet sclerophyll forest. Old records from New South Wales are now known to represent juvenile plants of M. johnsonii, although a single recent collection from the Border Ranges extends the range into far northern New South Wales.

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