   Notes: Statistics for midrib xylem conduit diameters are for the maximum cross-sectional diameters. Type of 3o order venation, from LAWG (1999): AP = alternate percurrent; MP= mixed opposite/alternate percurrent; OP = opposite percurrent; RPR = regular polygonal reticulate. M. argentea has four orders of major veins, with the density of 4o veins being 0.34 mm mm-2 ± 0.047 SE. Nomenclature follows Croat (1978); Tree Atlas of the Panama Canal Watershed; http://ctfs.si.edu/webatlas/maintreeatlas.html; Stevens (2005).
