say that this species is a doubtful one, although by some authors 

 it is thought that it is to be found in New Jersey, and south- 

 ward to North Carolina. 



Q. hypolenea. Engelm. Leaves thick, lanceolate, acute, 

 three or four inches long, and from three-quarters of an inch to 

 nearly an inch broad. Usually entire or slightly revolute on 

 the margin, but occasionally show one to three minute teeth. 

 Nearly smooth, and pale-green above, densely covered with yel- 

 lowish down beneath. Acorns small, sessile, solitary or in pairs, 

 ovate, and set in a roundish cup, pubescent obtuse scales. A 

 small tree, sometimes thirty feet high, near the copper mines, 

 New Mexico (Thurber). Southern Arizona, at an altitude of 

 seven thousand feet (Rothrock), and also in Sonora, Mexico. 



Q. imbiicaria, Michx. Shingle Oak, Laurel Oak. Leaves 

 three to five inches long, lanceolate-oblong, acute or obtuse at 

 each end, tipped with an abrupt short point, pale-downy be- 

 neath, deciduous. Acorn globular, five-eighths of an inch long, 

 cup enclosing about one-third of the nut, scales broad, whitish, 

 closely appressed. A large, stocky tree, forty to fifty feet high, 

 with quite smooth bark even on old trees. Wood hard, heavy, 

 coarse-grained', easily split, and occasionally used for making 

 shingles of an inferior quality. A handsome tree when young, 

 the leaves resembling those of the chestnut. In barren and 

 open woodland, from New Jersey westward. 



Q. ilici folia, Wang. Bear, or Black Scrub-oak. A low, dwarf 

 shrub, with leaves three to four inches long, obovate, wedge- 

 shaped at base, angularly, about five-lobed, white downy be-

 inch long. New England to Ohio, and southward. 



Q. Kelloggii. Newbury. Kellogg's Oak. Leaves deciduous, 

 thick, broadly oval, pinnatifid-lobed, the lobes tapering and 

 entire, or broad and lobed-dentate, at first downy, but soon be- 

 coming smooth, three to six inches long. Acorns oblong, over 

 an inch long, mostly on short stalks, one half to an inch long, 

 and several together ; cup round, but sometimes very deep, 

 with ovate-lanceolate imbricate scales. A medium or large- 

 sized tree with rough, black bark, in the Coast Ranges of Cali- 

 fornia. For various synonymes see Index. 



Q. laurifolia, Michx. Laurel-leaved Oak. Leaves three to 

 four inches long, oblong-lanceolate, entire or lobed, widest in
