Species with numerous leaflets; native to Panama and Colombia.

This species has reddish leaves and is native to cliffs in a small section of Tabasco, Mexico.

Species with long leaflets and wine-red seed cones; native to a small area of Cuna Yala, Panama, but not presently threatened.

Contains a picture and a claim that a starchy meal can be prepared from the swollen underground stem.

Extremely species with transparant, double toothed leaflets; has been found only in northern Colombia.

Species with large leaves, native to Panama.

Large species whose leaves have leaves with smooth petioles; found in Santander, Colombia.

Found in rocky areas of San Luis Potosi and Querétaro, Mexico; has proportionately large stems and seed cones.

Central American species with toothed leaflets; not well studied, but believed to be endangered.

Threatened species from Panama with elongate but broadly obovate leaflets.

Karapaná and Taiwano Indians often prepare a starchy meal from the underground part of this xerophytic plant that grows in relative profusion in the sandy savannah of Raudal de Jirijirimo.

Non-threatened species, with curved and slightly obovate leaflets; lives in East Chiapas, Mexico, and is able to regrow in burned areas.

Brief overview of the genus.

This species, found in Panama and Colombia, has a characteristic 'collar' around the base of each leaflet.

Unthreatened species native to Columbia; lives in lowland forests.

This endangered species, known by its long obovate leaflets, may be extinct in the wild. In any event, it lives only in Antioquia, Columbia.

Z. monticola is distinguished by its long, upturned, leaflet tips.

Found in coastal regions of Colombia and Venezuela, Z. muricata is distinguished by its teethed leaflets.

Found in Costa Rica and Panama, Z. neurophyllidia is essentially a smaller variant of Z. skinneri.

Provides a map showing where the taxon can be found as well as published resources.

Exhibits extreme variability in leaf and leaflet morphology which has been shown in a few cases where some leaves were in the sun and others were in the shade.

One of the Caribbean species of Zamia that is found only in Western Puerto Rico where it grows on very dry limestone soils that often contain an element of serpentine.

Endemic to Southwestern Costa Rica where it occurs on somewhat acidic soils in the understory of cloud forests from 1,000 to 1,300 meters.

Contains reddish seed cones with a distinct acuminate tip combined with leaflets with distinct apical teeth and is usually found in the Dominican Republic.

Is primarily found in rainforests from northern to central Atlantic Panama at elevations from 50 to 750 meters and contains a massive trunk, leaves, and strobili.

Linear-lanceolate leaflet with entire margins and an attenuate apices. Leaflets are often adaxially concave.

Has iridescent blue-green, oblong-lanceolate leaflets with entire margins and abruptly acuminate apices.

Contains a combination of symmetrical, almost perfectly elliptic to broadly lanceolate, leaflets with sharply serrated margins and acuminate apices and unarmed petioles and rachis.

Lists a publication concerning the taxon and where it can be found.

Contains a listing of published resources about the taxon.

The most endangered species of Zamia in Columbia which was discovered in 1875, collected once again in 1888 by Kalbreyer and then not seen again for 100 years.
