1918] SARGENT—CARYA 245 
subglobose, but rather broader than high, and conspicuously angled 
to the base, with a shell 4-5 mm. in thickness. The leaves of this 
form are 5-7, usually 7-foliolate. It is a tree with wide spreading 
branches, pale gray shallowly grooved close bark, slender glabrous 
bright red-brown lustrous branchlets, and acute winter-buds, the 
terminal 5-8 mm. long, their outer scales covered with gray 
pubescence.

13. CARYA OVALIS (Wangenheim), Sargent, Trees and Shrubs 
2:207. 1913.—This is the oldest name which can be used for the 
small-fruited hickories with globose or pear-shaped fruit opening 
usually as soon as ripe to the base generally by the 4 sutures of the 
thin involucre, and often with slightly scaly bark. The type of this 
tree and its varieties have glabrous or rarely slightly pubescent 
leaves, with usually 7 thin leaflets. The type of the species, judg- 
ing by WANGENHEIM’s figure, has short-oblong fruit rounded at 
base, acute at apex, 2.5—3 cm. long and about 1.5 cm. in diameter, 
with an involucre 2-2.5 mm. in thickness. This is one of the least 
common of the forms of this tree, and occurs from western NewYork 
and eastern Pennsylvania to Illinois, and southward to the moun- 
tains of North Carolina and Tennessee, and to central Georgia and 
Alabama. The following varieties can be distinguished: 
CARYA OVALIS var. OBCORDATA Sargent, l.c. 208. 1913, with 
subglobose to short-oblong fruit 2-3 cm. in diameter. The bark 
often separates into narrow scales, but on some trees shows no 
tendency to become scaly. 
This is the commonest and the most widely distributed of the northern 
forms of this tree and the Carya or Hicoria microcarpa of many recent authors. 
It is common in southern New England and ranges to Wisconsin, south- 
western Missouri, western North Carolina, central and eastern Georgia, eastern 
Mississippi, and to central Alabama, where it is very common in the mountain 
districts. On the Carolina mountains this tree grows to a large size and is _ 
sometimes called scaly-barked hickory. On dry ridges in Macon County, 
North Carolina, and near Birmingham, Alabama, the bark is close and 
darker, and some of the trees look distinct from the red color of the petioles 
which they retain during the season.
