Zamia integrifolia is actually a double misnomer because
'integrifolia' literally means entire leaves but was intended to
refer to the leaflets which are not entire but have small callous
teeth in the upper fourth.
Zamia integrifolia is more commonly labeled as Z. floridana
in the older literature particularly that concerning anatomy,
morphology and life cycles. This is mainly because the plants that
were studied came from Florida.
Leaflets with very small obscure callous bumps near the tips and
unusually large seed cones for the stature of the plant.
Distribution and habitat:
Zamia integrifolia is known from extreme southeastern Georgia
southward through peninsular Florida (including the Florida Keys)
and sporadically in the Bahamas where it occurs on Andros, Grand Bahama,
Great Abaco, Long, and New Providence Islands. It has been collected
in western Cuba, the Cayman Islands, and south-central Puerto Rico
where it may now be extinct. Habitats vary from open coastal areas
and sand dunes to pinelands and closed canopy oak hammocks to tropical
forest. This cycad is most commonly found in soil over limestone and
in sand near sea level or in pinelands subjected to periodic wildfires.
Zamia integrifolia is fairly common throughout its range
except in south-central Puerto Rico where it is extinct as a result
of over development early in the twentieth century. Not listed in the
1997 IUCN Red List of Threatened Plants
because it is not considered threatened.
