124 Trees with Simple Leaves. [Am 



Acorns, large and stemless, or nearly so. *Cup, flat saucer- 

 shape, bulging, very shallow,- nearly smooth, with 

 small scales. Nut, about one inch long, somewhat 

 egg-shape ; bitter. October. 



Found, from Nova Scotia and New Brunswick westward and 

 southward. Very common, especially at the North, and 

 extending farther north than any other Atlantic oak. 

 A tree fifty to eighty feet high, with wood that at the 

 East is porous and not durable (though often of better 

 quality westward). It is used for clapboards and in 

 cooperage. The leaves change in the fall to dark red. 



Fig. 64. Pin Oak, Swamp Spanish Oak, Water Oak. Q. 



palustris, D. Roi. 



Leaves, SIMPLE ; ALTERNATE ; EDGE LOBED (edges of the 

 lobes mostly entire, but notched and toothed towards 

 the ends). 



Outline, narrow oval or broad oval. Base, from long 

 wedge-shape to squared. Ends of lobes and of the 

 teeth pointed and bristle-tipped.

 smooth, and shining ; downy in the angles of the ribs 

 below. Lobes, seven to nine, usually seven, with the 

 hollows between them broad and round and usually 

 reaching about three fourths of the way or more to

 sembles the leaves of the scarlet oak, but it is smaller 

 and usually the hollows reach nearer to the middle rib.

Acorns, numerous, small, on short stems. Cup, top-shaped, 

 shallow, and nearly smooth. Nut, rounded, one half 

 inch long or less, sometimes broader than long, light
