 at maturity thick and firm, glabrous, dark green and very lustrous above, pale below, 1|'- 

 2' long, and f wide, with 4 or 5 pairs of thin primary veins conspicuous on the under side 

 and extending obliquely from the slender midrib to the end of the lobes; petioles usually 

 about j' in length, slightly glandular above the middle, and covered when they first appear 

 with short pale deciduous hairs; leaves at the end of vigorous shoots deeply divided into 

 broad acute lateral lobes, '-3' long, and l\ f wide. Flowers opening in May and June, cup-

A tree, 20-25high, with a trunk occasionally 1 in diameter, stout spreading branches

Leaves oblong-obovate to oval, or broad-ovate, acute or rarely rounded and short- 

 pointed at apex, gradually or abruptly narrowed at base, and coarsely and usually doubly 

 serrate except toward the base, when they unfold dark green, lustrous and roughened above 

 by short pale appressed caducous hairs and pale yellow-green and villose on the midrib and 

 primary veins below, about half grown when the flowers open early in May and at matu- 

 rity thin and 'firm in texture, dark green and lustrous on the upper surface, pale yellow-green

 veins after midsummer often bright red below ; turning late in the autumn to brilliant shades 

 of orange or scarlet or deep rich bronze color; petioles often glandular, at first coated with 

 pale hairs, soon glabrous, dull red at maturity, \'-\' in length; leaves at the end of vigorous 

 shoots often slightly lobed with short broad acute lobes, convex by the hanging down of the 

 margins, 3'-4' long, and 2'-3' wide. Flowers f in diameter, on slender pedicels, in wide 

 many-flowered slightly villose corymbs, with large glandular bracts and bractlets; calyx-
