 ous. Flowers: staminate in aments 3'-4' long and coated like the ovate-oblong acute 

 bract and calyx of the flower with dark brown scurfy pubescence; stamens 6, with yellow 

 anthers; pistillate oblong, narrowed at the ends, slightly 4-angled, covered with thick 

 brown scurfy pubescence. Fruit usually solitary, ellipsoidal or slightly obovoid, 4-ridge"d 

 to the base, with broad thick ridges, 1|' long, coated with yellow-brown scurfy pubescence, 

 the husk not more than ^V thick, splitting nearly ^o the base; nut ellipsoidal or some- 

 times slightly obovoid, 1' long, f ' broad, rounded and apiculate at the ends, smooth, dark 

 reddish brown, and marked by longitudinal broken bands of small gray spots covering 

 the entire surface at the ends with a thick hard and bony shell, a thick partition, and a 

 low thin dorsal division; seed sweet, small, dark brown; the lobes deeply 2-lobed at apex. 



A tree, 80-100 high, with a tall straight trunk often 2 in diameter, stout slightly 

 spreading branches forming a comparatively narrow rather open head, and slender branch- 

 lets coated with lustrous golden or brown scales often persistent until the second year, 

 light brown or ashy gray during their first winter, ultimately dark reddish brown, and 

 marked by small scattered pale lenticels and small oval emarginate elevated leaf-scars. 

 Winter-buds covered with thick brown scurvy pubescence; terminal \'-\' long, ovoid, 

 rather obtuse; axillary much smaller, acute, slightly flattened, sessile or short-stalked,

thickly ciliate on the margins, finely serrate except toward the usually cuneate base, dark
