Evidence is provided substantiating (1) a more taxonomically sound application of the name Zamia skinneri Warsz. ex A.Dietr. to populations of green‐emergent, plicate‐leaved plants from coastal mainland Bocas del Toro, Panama and (2) the lack of a formal name for the red‐emergent, plicate‐leaved plants from north‐central Panama. Re‐characterization of Z. skinneri is followed by a discussion of the status of Z. neurophyllidia D.W.Stev. and formal descriptions of three endemic, arborescent, plicate‐leaved cycads from northwestern and central Atlantic Panama: Z. hamannii sp. nov., Z. imperialis sp. nov. and Z. nesophila sp. nov. Also included is a brief discussion of taxonomic relationships within the group, a key to the plicate‐leaved cycads of Panama and a hypothesis for the historical biogeography and evolution of the skinneri complex. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 158 , 399–429.
