Description of the family
Trees. Trunk tall or very short, bearing spirally arranged leaf-bases and scale leaves. Leaves closely spirally arranged, pinnate; leaflets with one thick midrib and no lateral veins, entire. Male scales arranged in apical cones, each scale with many pollen-sacs on the abaxial surface. Female scales frond-like, lanceolate or narrowly ovate, irregularly dentate, not forming a definite cone but spirally arranged in an apical whorl. Seeds ovoid.
May be distinguished from the Zamiaceae by the presence of a midrib in the leaflets and by the female inflorescence which is much-branched and not cone-like. The Stangeriaceae leaflets also have a midrib, but they differ in the presence of lateral veins.
Worldwide: 1 genus and 17 species extending from Africa to Japan and Australia
Zimbabwe: 1 cultivated genus and 2 cultivated taxa.
