 pubescent below, and usually about 3' long and 2' wide, with a slender midrib, remote 

 primary veins extending to the point of the lobes, conspicuous secondary veins, and retic- 

 ulate veinlets; petioles more or less winged toward the apex, tomentose early in the season, 

 becoming pubescent, f '-f in length; leaves at the end of vigorous shoots often 5' long and 

 3' wide, with rounded, acute lobes. Flowers f ' in diameter, on long stout hoary-tomentose 

 pedicels, in broad loose many-flowered tomentose corymbs, with oblong-obovate to lance- 

 olate finely glandular-serrate villose conspicuous bracts and bractlets; calyx-tube broadly 

 obconic, covered with thick pale tomentum, the lobes broad, acute, very coarsely glandular- 

 serrate, tomentose on the outer surface and villose on the inner surface; stamens 20, anthers

A tree, lo-20 high, with a tall straight trunk 8'-10'in diameter, covered with thin dark 

 brown furrowed bark, spreading branches forming a broad open head, and branchlets 

 hoary-tomentose at first, soon puberulous, dull reddish brown or yellow-brow r n by mid-
