Z. angustifolia has dark gray to black strobili (cones) with acuminate points.

The limited number of plants and sites, and the development of nearby areas for housing create the highest concern for conservation of the Bahamian population of the species.

[5] It is abundant in Cuba, but the taxonomic relationship between the Bahamian and Cuban populations needs further study.

[6] In 1889 Gardiner and Brace listed just one Zamia species in the Bahamas, Z. angustifolia, which they referred to as "bay rush".

They reported that plants of the species were harvested on Andros and New Providence islands to produce starch sold in Nassau markets.
