DECIDUOUS TREES. 
The OLive-ACORN or Mossy-cup Oak. Q. oliveiforJuis.—This 
variety is known by some under the name of mossy-cup oak. As 
the burr oak has a still mossier cup, it seems to us that the botani- 
cal name which Loudon has anglicized, and which is given above, 
is more appropriate. Its acorn is long, like the olive, and nearly 
covered by its cup, but not so completely as that of the burr oak. 
The leaf of this variety is like a white oak leaf, elongated, and more 
deeply lobed. Its bark is like that of the white oak, but the growth 
is more slender, and the branches tend to droop gracefully. A 
native of the northern States. 
The Chestnut Oak Group. 
The Chestnut Oak. Quercus prinus palustris . — 
A lofty tree found principally below the latitude of 
42°. It is disposed to form a straight trunk, with- 
out branches to a considerable height, and then to 
spread into a broad tufted head. Fig. 97 shows its 
form of leaf. We have not had the good fortune to 
see any trees of this variety grown to maturity in 
open ground, and cannot, therefore, speak of its usual 
character as an ornamental tree ; but our impression is that for 
massy and glossy foliage, and rapidity of growth, it is surpassed 
by few of the oaks. When young its growth is long-limbed like the 
red oaks. At all times a cleanly-looking tree. 
The Rock Chestnut Oak. Q. prmus monticola. — Down- 
ing considers this one of the finest of northern oaks, and states that 
it grows on the most barren and rocky soils ; thus showing its 
affinity to its namesake and prototype, the chestnut tree. “ In open 
elevated situations it spreads widely, and forms a head like that of 
an apple tree.” The leaves are broader proportionally, and less 
acutely pointed than those of the preceding variety, by which, and 
its lower and broader form, it can be recognized. We consider 
this the finest of the chestnut oak family, and for small grounds the 
most desirable oak to plant, being more opulent in leaves than 
any other.
