Abstract
Zamia sandovalii is an acaulescent, cremnophilous cycad with long, pendulous leaves endemic to the Department of Atlántida, Honduras. The original description, though valid, is lacking a thorough and robust elaboration of its characteristics, which is provided here. Also included here is a treatise on its taxonomic and biogeographic affinities and a diagnostic key to the Z. splendens species complex as circumscribed herein.
