five, and sometimes three acute lobes, terminated by a bristle. 

 They are of a pale color underneath, and downy on the same side 

 when young. The acorns are small, short, dark colored and 

 striated. 



The shrub oak grows on dry hills and barren plains, and is 

 commonly considered an indication of a sterile soil. On account 

 of its small size, it is rarely appropriated to any important use.

Leafets numerous, oblong lanceolate, rounded at 

 base, downy underneath, serraJe. Fruit oblong- 

 ovate with a terminal projection, viscid and hairy; 

 nut oblong, acuminate, with a rough, indented and 

 ragged surface. 



The leaves of the Butternut, when fully grown, are very long, 

 consisting of fifteen or seventeen leafets, each of which is two 

 or three inches in length, rounded at base, acuminate, finely ser- 

 rate and downy. The flowers appear in May, before the leaves 

 are expanded to their full size. The barren flowers hang in 

 large arnents from the sides of the last year's shoots, near their 

 extremities. The scales which compose them are oblong and 

 deeply cleft on each side into about three teeth or segments. 

 The anthers are about eight or ten in number, oblong and 

 nearly sessile. The fertile flowers grow in a short spike at the 

 end of the new shoot. They are sessile, pubescent, and viscid. 

 When fully grown, they seem to consist of a large oblong germ 

 and a forked feathery style. The top of the germ presents an 

 obscurely four toothed calyx. Within this is a corolla of four 

 narrow lanceolate petals, growing to the sides of the style. The 

 style divides into two large, diverging, feathery stigmas nearly 

 as long as the germ. These flowers are somewhat later than 

 the aments in their appearance. The fruit is sessile, several 

 together on the sides and extremity of a long peduncle. It is of 

 a green color, brown when ripe, oblong-oval, pointed, hairy 

 and extremely viscid. It contains a nut which is of a dark
