Engravings. Michx. N. Amer. Syl., 3. t. 137 3 our jigs. 1812. from Dropmore, and 1813. from Mi- 
chaux, to our asual scale; and figs. 1809, 1810, and 1811., of the natural size. 
Spec. Char., &c. Leaves long, slender ; hollowed on the upper surface. Cones 
small, ovate-conical. Scales with their outer surface slightly prominent, and 
terminating in a very small slender mucro, 
pointing outwards. (Michx.) Buds, ona 
young tree (fig. 1809.), 8; in. long, 
and 4-in. broad; on an old tree, 
larger (fig. 1810.) ; scarcely resinous, 
) Leaves (jig. 1811. from Michaux) \ 
from 23 in. to 4in. long, with sheaths 
Zin. long; white, lacerated, afterwards 
becoming dark, slightly ringed. Cone 
2 in. long, and 1 in. broad in the widest 
uy part. Seeds small; with the wing, 
| 2in. long. Young shoots covered 
. with a violet-coloured glaucous bloom, 
like those of P. inops, by which it is 
readily distinguished from the P. variabilis 
of Lambert. A beautiful tree, much valued 
in America for its timber. New Eng- 
land to Georgia, in most pine forests, in 
various parts of the United States. Height 
50 ft. to 60 ft. in America, and also in Eng- 
land ; with a trunk of the uniform diameter of 15 or 18 inches, for nearly 
two thirds of its length. Introduced in 1739. Flowers in May, and its 
cones are ripened in November of the second year. 
1810. P. mitis. 
The branches are spreading on the lower part of the trunk, but become less 
divergent as they approach the head of the tree, where they are bent towards the 
; body soas to forma summit regularly pyramidal ; 
but not spacious in proportion to the dimensions 
ofthe trunk. This narrow conical appearance 
of the head, as compared with the spreading 
character of those of other species, seems to 
have given rise to the 
name of spruce pine in 
America. The leaves, 
according to Michaux, 
are 4 or 5 inches long, 
fine and flexible, hol- 
lowed on the upper 
surface, of a dark green, 
and united in pairs. 
Sometimes, from luxu- 
riancy of vegetation, 
three leaves ure found 
in the same sheath on 
young shoots, but never 
on old branches. The 
P. variabilis of Lam- 
bert’s Pinus, which is 
made a synonyme of 
this species by Pursh, 
is unquestionably a to-
