Abstract

Dion edule is distributed through the Sierra Madre Oriental from Veracruz to Nuevo Leon and in dijunct stations in Tamaulipas. The most significant variation consists in the reduction of leaflet width from the south northwards. On this basis, two varieties are recognized:D. edule var.edule, characterized by wide leaflets and a distribution in Veracruz, Hidalgo, Queretaro, San Luis Potosi and southern Tamaulipas, andD. edule var.angustifolium, with narrow leaflets and a distribution in central-northern Tamaulipas and Nuevo Leon.
