Q. Emoryi, Torr. — Dwarf Evergreen Oak. — Leaves small, ever- 

 green, slightly lobed, acorns very small. A widely spread 

 shrubby evergreen oak m Southern Texas, New Mexico, Arizona, 

 and southward in Mexico. 



Q. falcatej Michx. — Spanish Oak. — Leaves oblong, rounded at 

 the base, three to five-lobed ; the lobes entire or sparingly 

 toothed at the apex, the terminal one commonly narrow and 

 elongated. Acorns about a half inch long, set in a cup enclos-

 feet high, and stem four feet in diameter. Wood dark-brown 

 or reddish, coarse-grained, decays rapidly when exposed to, 

 moisture. Bark thick, rich in tannin, and often extensively 

 employed by tanners in making what is called "Oak-tanned 

 Leather." New Jersey, southward to Florida, and westward to

Q. lietcrophylla, Michx. — Bartram Oak. — Dr. Engelmann places 

 this among the hybrid oaks, and intermediate between Q. Phel-

 aguatiea, which in some respects it certainly very much resem-
