However, the peak in the northern tropics is largely due to " Cycas " in Asia and " Zamia " in the New World, whereas the peak in the southern tropics is due to " Cycas " again, and also to the diverse genus " Encephalartos " in southern and central Africa and " Macrozamia " in Australia.

While the cycads have a reputation of slow growth, it is not always well-founded, and some actually grow quite fast, achieving reproductive maturity in 2 & ndash; 3 years ( as with some " Zamia " species ), while others in 15 years ( as with some " Cycas ", Australian " Macrozamia " and " Lepidozamia " ).

Two plant species, in particular, are considered Carnarvon Gorge icons; the cycad " Macrozamia moorei " ( no common name ) and the Carnarvon fan palm ( " Livistona " " nitida " ) . " Macrozamia moorei " is closely associated with the Tertiary basalt flows of the Buckland Volcanic Province, and is endemic to Central Queensland . " Livistona nitida " is endemic to the springs and waterways of the Dawson River catchment, and Carnarvon Gorge is considered its stronghold.
