Medium-sized or large tree. Twigs 1.5 to 2 or 3 mm. thick, fluted 

 or subterete, dark reddish brown with usually conspicuous lenticels, 

 from more or less densely stellate-tomentose promptly or tardily gla- 

 brate or persistently tomentulose. Buds 4 to 5 mm. long, 1.5 to 2.5 

 mm. broad, fusiform or ovoid, from pubescent becoming glabrate; 

 stipules caducous. Leaves apparently deciduous, thick and firm, 3 to 

 usually 8 or 10 or even 14 cm. long, 1.5 to usually 4 or even 6 cm. broad, 

 oblong-elliptic to obovate or oblanceolate, rarely lanceolate, usually 

 broadest above the middle, rounded to acute or exceptionally acumi- 

 nate at apex, in any event aristate- tipped, cuneate to rounded, trun- 

 cate, or cordate at base, entire to coarsely several-toothed or sublo- 

 bate, the lobes broadly rounded but aristate-tipped, usually merely 

 undulate or few-toothed toward the apex, the margins often coarsely 

 crisped, minutely or coarsely revolute, upper surface somewhat shin-

 about the base of the midrib, lower surface dull, from densely velvety-

 low- or granular-bullate ; veins 9 to 12 or 15 on each side, branched 

 and anastomosing near the margin, impressed above, quite promi-
