    Distribution (Map).  Guatemala, Mexico, Panama, and Colombia, at elevations of 250-2200 m.  In Mexico it is usually found in montane cloud forests dominated by Pinus-Quercus-Liquidambar, but has also been recorded from limestone areas.  In Guatemala it occurs in virgin or disturbed forest, wet ravines, or along fence-rows.  In Panama it is found only in the wet cloud forests of Cerro Pirre, Darién Prov., and I have collected it along steep roadsides and forest edge in Chocó Dept., Colombia (see Luteyn & Sylva S., 1999)
