paler beneath, prominently veiny and sparsely pubescent on both 
faces: terminal leaflet 14 to 1? inches long, cuneate-obovate, 
obtuse, coarsely crenate from below the middle, slightly 3-lobed 
near the summit; laterals more than half as large, less cuneate

Rocky hills of Osborne Co., Kansas, 9 June, 1894, ©. L. Shear,

branches tortuous and knotted, twigs of the season puberulent: 
foliage small, of the texture, color and indentation of leaflets of 
white oak ; terminal leaflet ł to 14 inches long, obovate-cunei- 
form, 3-lobed above the middle, the rounded lobes entire, or 
oftener crenate, all lobes and teeth very obtuse; laterals more

foliage of different figure and that less uniform, some with all 
three leaflets cuneate-obovate and quite entire, the more usual 
terminal leaflet 1 to 14 inches long, obovate-cuneiform, or more 
commonly cuneate-obovate, angularly and rather coarsely about
