 flattened and pubescent at the ends, dark red; calyx prominent, with more or less decid- 

 uous lobes; nutlets 3-5, narrowed and acute at the ends, rounded and very irregularly 

 ridged and sometimes obscurely grooved on the back, about \' long. 



A tree, 20-25 high, with a tall trunk 10'-12' in diameter, thick spreading branches

 winged toward the apex, at first villose, soon glabrous, about \' long, often bright red in the 

 autumn; leaves at the end of vigorous shoots sometimes oblong or oval, coarsely dentate, 

 usually divided above the middle into short acute lobes, 3'-4' long, 2'-2' wide, and de-
