with loose pale or rufous tomentum, and have hirsute yello 



bsessile anthers more or less deeply 



emarginate at the apex. The pistillate flowers are usually produced in two to five-flowered spikes and 

 are oblong-ovate, about twice as long as they are broad, slightly angled, and clothed with pale tomen- 

 tum, with linear acute bracts much longer than the nearly triangular bractlets and calyx-lobes ; the

The fruit, which 



solitary or in pairs, is ellipsoidal

orange-colored lenticels, downy with pale pubescence, or glabrate, light orange-colored or dark chestnut- 

 brown at maturity, from an inch and three quarters to two and a half inches long and from an inch and 

 a quarter to two inches broad, with a hard woody husk, pale and marked on the inside with dark con- 

 spicuous veins, and from a quarter to a third of an inch in thickness. The nut is ellipsoidal or slightly 

 obovate, longer than it is broad, or sometimes as broad or broader than it is long, flat and rounded at 

 both ends or gradually narrowed and rounded at the base, sometimes acuminate at the apex, more or less 

 compressed, rather prominently four-ridged and angled or often six-ridged, full and rounded on the back 

 of the two valves, furnished at the base with a stout long point, slightly reticulate-rugose, light yeUow

 inch and a half to an inch and three quarters in breadth, with a hard and bony shell from one eighth to 

 one quarter of an inch in thickness. The seed, which is covered by a lustrous light chestnut-brown 

 coat and is very sweet with an agreeable flavor, is divided nearly to the apex by the dorsal partition of
