Taxonomical, nomenclatural and biogeographical revelations in the Zamia skinneri complex of Central America (Cycadales: Zamiaceae)
Abstract
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.
