The Outer Epidermis {aep) corresponds with the ])alisade layerof other legumes, although the two appear at first sight to have notiiingin common. The cells are 15-25 /< high and 25-50 /« broad. Cross PEANUT. 273 sections show that the inner walls are thin, but that the radial walls in-crease in thickness from within outward, and as a consequence the cavitiesare more or less triangular in shape.
