"TYPE: Mexico: Tabasco. 18 Aug 1981, M.A. Magana 343 (holo MEXU, iso XAL)."


Etymology: Cliff-loving in reference to habitat preference

Historical notes:

Distinguishing features: Purplish red pendant leaves with imbricate leaflets. Stems usually decumbent even when grown in pots.

Distribution and habitat: Endemic to a small area of Tabasco, Mexico in well-drained calcareous cliffs.

Conservation status: Zamia cremnophila is locally abundant and being propagated from seed in local nurseries. Hence its future seems assured in terms of over collection. 1997 IUCN Red List of Threatened Plants Category V,II,V.
