Leaves 9'-18' long, with a stout tomentose petiole, and usually 7 but occasionally 9 lance- 

 olate or elliptic entire or slightly serrate leaflets acuminate or abruptly long-pointed at 

 apex, rounded, cuneate and often unsymmetric at base, coated below when they unfold 

 with hoary tomentum, and pilose on the upper surface with short pale hairs, particularly 

 on the midrib and veins, and at maturity thick and firm in texture, dark yellow-green and 

 nearly glabrous on the upper surface, soft-pubescent on the lower surface, 5'-10' long and 

 l^'-5' wide, with a stout yellow midrib deeply impressed and puberulous above and numer- 

 ous slender primary veins; petiolules stout, tomentose early in the season, usually becom- 

 ing glabrous or nearly glabrous, \'-% r or that of the terminal leaflet up to 2' in length. 

 Flowers dioecious, in elongated much-branched pubescent panicles, with oblong or oblong- 

 obovate scarious bracts and bractlets; staminate flower with a minute campanula te ob- 

 scurely 4-toothed calyx, and 2 or 3 stamens, with comparatively long slender filaments and 

 oblong apiculate anthers; pistillate flower with a large deeply lobed calyx accrescent and 

 persistent under the fruit, and an ovary gradually contracted into a slender style. Fruit 

 in long drooping many-fruited pubescent clusters, oblong, 2'-3' in length and often ' wide, 

 the wing sometimes falcate, rounded, apiculate, or emarginate at apex, and decurrent to 

 below the middle or nearly to the base of the thick terete many-rayed body. 



A tree, occasionally 120 high, with a slender trunk 3 in diameter above the much en- 

 larged and buttressed base, small spreading branches forming a narrow rather open head, 

 and stout branchlets marked by large pale lenticels, coated at first with hoary tomentum, 

 tomentose and pubescent during their first winter and light gray and pilose or glabrous the
