Trees for Shade and Ornament 



Q. macrocarpa Michx. (286), Bur Oak or Mossy Cup Oak (so called 

 from the hairy cup of the acorn), is of more northern distribution, the 

 hardiest of them all, a very picturesque tree of more or less fan-shaped 

 form, the bark darker than the white oak, and corky on the branches; 



Q. lyrata Walt. (287), Swamp or Over-cup Oak (so called from the 

 cup enclosing the acorn entirely), is of more southern distribution, from 

 New Jersey to Texas, frequenting moist to swampy situations; forms a 

 round-topped head with rather short and somewhat pendulous branches; 



Q. stellata Wangh. (288) (oblusiloba or minor), Post Oak, a smaller 

 tree (sixty feet), with a handsome, dense round head, or else with open, 

 straggling branch habit, and brownish, fissured bark. It is adapted 

 to dry, rocky, or sandy soil. 



Another type of foliage, resembling somewhat the chestnut leaf 

 with short, rounded lobes, and hence called Chestnut Oak, is charac- 

 teristic of the following three: 



Q. Prinus Linn. (289) {montana). Chestnut Oak, Rock Oak, of wide 

 distribution, especially on rocky mountain slopes, and adapted to dry 

 soils; a tree not much larger than the Post Oak, with a somewhat 

 unsymmetrical broad crown and dark ridgy bark; 



Q. Michauxi Nutt. (290), Basket Oak, Cow Oak, of more southern 

 range (from Delaware to Texas), is a larger tree with rather dense 

 round head and grows preferably in moist soil; large (four to seven 

 inch) foliage, grayish underneath, and a very light gray scaly bark; 



Q. Muhlenbergi Engelm. (291), Yellow Chestnut Oak, of southern 

 and western range, is a large tree with a narrow round-topped head, 

 particularly attractive in its handsome foliage, which is glossy above 

 and silvery white beneath, and with light gray flaky bark. 



B. BLACK OAKS 



Q. velutina Lam. (292) (tinctoria), Black Oak, Quercitron Oak, is 

 the type of the black oaks; ranging from Maine to Texas; a tall tree 

 with rather slender branches forming a narrow open head, the leaves 

 very large (up to ten inches), very symmetrically cut, dark green above 

 and yellowish brown beneath, turning orange; the bark almost black, 

 and ridgy (the inner bark orange, whence the name Quercitron). It is 

 a very rapid grower, adapted to any soil. 



Q. rubra Linn. (293), Red Oak, of as wide range and of the same 

 dimensions as the preceding, but with its stout spreading branches
