Distribution. Deep river swamps often inundated during several months of the year; 

 western New York (H. F. Sartwell}; southern Indiana and Illinois; western Kentucky 

 (Caldwell and McCracken Counties) and Tennessee (Henderson CountvV. southeastern

Leaves 10'-12' long, with a stout slightly grooved pubescent petiole, and 7-9 oblong- 

 lanceolate, ovate-elliptic or slightly obovate leaflets gradually narrowed at apex into a long 

 slender point, unequally cuneate at base, and obscurely serrate, or often entire below the 

 middle, when they unfold coated below and on the petiole with hoary tomentum, and 

 lustrous and puberulous on the upper surface, and at maturity thin and firm, 4 '-6' long, 

 l'-l' wide, light yellow-green above and pale and covered below with silky pubescence, 

 with a conspicuous midrib aid branching veins; in the autumn turning yellow or rusty 

 brown before falling; petiolules thick, grooved, pubescent, |'-|' or that of the terminal 

 leaflet up to 1' in length. Flowers dioecious, appearing late in spring as the leaves begin to 

 unfold, in a rather compact tomentose panicle, covered in the bud with ovate rusty-tomen- 

 tose scales; staminate flower with a minute obscurely toothed cup-shaped calyx, and 2 

 stamens, with short slender filaments and linear-oblong light green anthers tinged with 

 purple; calyx of the pistillate flower cup-shaped, deeply divided, as long as the ovary gradu- 

 ally narrowed into an elongated style divided at apex into 2 green stigmatic lobes. Fruit in 

 an open glabrous or pubescent panicle, lanceolate to slightly oblanceolate or oblong-obovate 

 or elliptic, 1/-2J' long, \'-\ r wide, surrounded at base by the persistent calyx, the thin wing 

 narrowed, rounded and occasionally emarginate or acute or acuminate and often apiculate 

 at apex, decurrent to below the middle or nearly to the gradually tapering base of the slen- 

 der terete many-rayed body.
