 all its parts ; red-brown twigs of the season slightly rugose : 

 leaves large, on stout petioles 3 to 5 inches long ; odd leaflet 

 commonly 5 inches long and nearly 3 in breadth, of somewhat 

 rhombic-ovate outline, cuneate at base, cuspidately pointed at 

 apex but the cusp not acute, usually blunt and commonly even 

 emarginate, the whole margin faintly crenate, upper face deep 

 green, lower glaucous, lateral leaflets nearly one-third smaller, 

 not strongly inequilateral : samaras small for the plant, hardl)' 

 more than one-half inch in diameter, nearly orbicular, retuse at

 moderately punctate between the ridges ; reticulation of wing

 copious type specimens all in his private herbarium. Readily dis-

 merely acute, not taper-pointed, the margin faintly crenate, the 

 lateral pair about one-third smaller, very inequilateral : samaras 

 very large, some quite an inch long, round-obcordate, abrupt!)' 

 acute at base, the summit with a short sinus between the rounded
