"TYPE: Panama, Cuna Yale, Comarca de San Blas, 18 Jan 1989, Stevenson et al. 1153 (holo NY iso F, FTG, K, MO, NY, PMA, U)."[NY][NY]


Etymology: Named in honor of the Cuna Indians who use the seeds to make necklaces. In Cuna, the plant is known as "obset" and the ovulate strobilus as "obset e sana".

Historical notes:

Distinguishing features: The generally obvious long oblanceolate leaflets and wine-red seed cones.

Distribution and habitat: Endemic to Cuna Yala (Comarca de San Blas), Panama. Zamia cunaria is usually found in clay soils on slopes and ridge tops from 400-800 m in secondary vegetation.

Conservation status: Only three small populations are known. Seed set appears high and the populations are not, at this time, threatened by development or destruction. 1997 IUCN Red List of Threatened Plants Category V,II,R.
