[Derivation equivocal, perhaps from misreading of Latin azania, a kind of pine cone, or from Latin zamia, loss, from the "sterile appearance" of the pollen cones]
Stems often branched, subterranean to aboveground. Leaves broadly oblong-elliptic; leaflets entire to coarsely dentate, without midribs, venation dichotomous but appearing parallel. Cones distinctly peduncled. Pollen cones more slender than seed cones. x = 8.
Species ca. 30 (1 in the flora): subtropics and tropics, North America, Mexico, West Indies, Central America, South America.
