Colombiapresent (World Checklist of Arecaceae)B
Western slope of the Cordillera Occidental in Colombia (Antioquia); forest on steep slopes at 950-1600 m. This area may be a center of endemism - e.g., Wettinia disticha (R. Bernal) R. Bernal, Zamia wallisii Regel - and many Erieaceae are known only from this locality. (Gloria Galeano & A. Henderson, Flora Neotropica Monograph 72)A
