A tree with slender glabrous branchlets densely coated when they first appear with pale 

 pubescence, soon glabrous, light reddish brown during their first summer, often bright red 

 during their first winter, becoming purple the following year and ultimately light gray- 

 brown. Winter-buds ovoid, glabrous or puberulous, bright red, about ' long and T V-'

Leaves ovate, abruptly narrowed and acuminate at apex, usually oblique and unsym- 

 metrically cordate or truncate or occasionally symmetrical and cordate at base, crenately 

 serrate, the teeth tipped with minute glands, covered when they unfold with pale caducous 

 tomentum, and at maturity dark green and lustrous above, glaucescent below, glabrous 

 with the exception of minute axillary tufts of rusty hairs, mostly 3f '-5|' long and 2f '-3' 

 wide; petioles slender, glabrous, about 1 \' in length. Flowers opening the middle of June,

 peduncle glabrous, the free portion l'-l|' in length, its bract oblong-obovate, cuneate at 

 base, rounded at apex, glabrous, 3'-5' long, usually about f ' wide, decurrent nearly to the 

 base of the peduncle; sepals acute, hoary-tomentose on the outer surface, coated with pale 

 tomentum mixed with long white hairs on the inner surface; petals narrow-acuminate; 

 staminodia oblong-obovate, notched at apex. Fruit ripening from the middle to the end 

 of August, ellipsoid, conspicuously apiculate at apex, rusty-tomentose, \'-%' long and ? f -\'

Leaves broad-ovate, acuminate or abruptly acuminate at apex, cordate or obliquely 

 truncate at base and coarsely serrate with apiculate teeth, tinged with red and tomentose 

 helow when they unfold, fully grown and glabrous or nearly glabrous when the flowers open 

 late in May or in early June, and at maturity thin, glabrous, dark yellow-green on. the 

 upper surface, pale or rarely covered below with a silvery white bloom (var. hypoleuca 

 Sarg.), 3^'-5' long and 2|'-3|' wide, with a slender midrib and primary veins; in the east 

 usually without axillary tufts, often present and sometimes conspicuous westward; petioles 

 slender, glabrous, f'-l' in length. Flowers opening in early summer '-|' long, on hoary-
