young tree (fig . 1809.), in. long,
and -^ in . broad ; on an old tree,
larger (fig. 1810.) ; scarcely resinous.
Leaves (fig- 1811. from Michaux)
from in. to 4 in. long, with sheaths
A in. long; white, lacerated, afterwards
becoming dark, slightly ringed. Cone
2 in. long, and 1 in. broad in the widest
part. Seeds small; with the wing,
in. long. Young shoots covered
1809. with a violet-coloured glaucous bloom,
like those of P. inops, by which it is
readily distinguished from the P. variábilis
of Lambert. A beautiful tree, much valued
in America for its timber.^ New England
to Georgia, in most pine forests, in
various parts of the United States. Height
50 ft. to 60 ft. in America, and also in England
; 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.
The branches are spreading on the lower part of the trunk, but become less
divergent as they approach the head ofthe tree, where they are bent towards the
body so as to form a summit regularly pyramidal;
but not spacious in proportion to the dimensions
of the 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, hollowed
on the upper
surface, of a dark green,
and united in pairs.
Sometimes, from luxu-
riancy of vegetation,
three leaves are found
in the same sheath on
young shoots, but never
on old branches. The
P. variábilis of Lambert’s
Pinus, which is
made a synonyme of
this species by Pursh,
is unquestionably a to-

thc P. mitis of Michaux ; being without the
violet-coloured glaucous bloom on the young
slioots ; having rigid leaves, generally in threes ;
and a cone with very strong prickles, like that of
F. Paj'da, to which species we have referred it.
The only plants that we know which answer to
Michaux’s description of P. mitis are at Drop-
more, where they are readily known by the violet-
coloured glaucous bloom on the young shoots,
and by the leaves being almost all in twos ; at
the same time, it is proper to mention that the
leaves there, though soit and slender, are much
shorter than those in Michaux’s figure. The
name applied to this species at Dropmore is P.
variábilis. There is also a plant at Dropmore
named P. mitis ; but it is wholly with three
'eaves ; and, as far as we can ascertain (the
tree not having yet borne cones), it belongs

either to P. serótina, or to some variety of it.
The description given
by Miller of P. echinàta, as having finely elongated leaves, and á cone "with
very slight slender prickles, agrees perfectly well with this species, as descril>ed
by Michaux ; and not at all with Mr. Lambert’s P. variábilis, which he describes
as having leaves only 2 in. long, and cones with scales having “ thorny
points of a strong woody texture projecting from them.” ”
Í 16. P. c o n t o ' r t a Douglas. The twisted-ázwzc/zé’íí Pine.
Buds roundish, with a hhint point, covered with resin, and brown. Leaves
2 in a sheath, 2 in. long ; sheath very short, imbricated, black. Cones from
2 in. to 2-A in. long ; and from f in. to 1 in. broad ; scales with the apices having
a depressed lateral rib, terminating
in a blunt point, furnished
with a caducous mucro.
The shoots are regularly and
closely covered with leaves,
much in the same manner as
those of P. (s ) ¡iiunilio, to
which the specimen sent home
by Douglas, in the IL.'rticuI-
tui-al Society’s herbarium,
bears a general resemblance.
This pine was found by I
Douglas in North-west Arne-
rica, on swampy ground near
the sea coast ; and, abundantly,
near Cape Disappointment

¥ 17. P. TURBINA TA Bosc. The Top-shaped-cojzcó? Pine.
Leaves 2 in a sheath, slightly glaucous, scarcely 1 in. long. The huds
are very small, reddish, fringed, and not resinous. The cones are in whorls
from 2 to 5 together, sharply pointed, longer than the leaves, with the scales
almost square, and not pM'amidal. Bosc thinks that it is probably a native
of North America ; but his description is taken from a tree in the garden of
the Petit Trianon, about 40 ft. high, the only one he liad seen. He adds that
Its general appearance resembles that of P. mitis ; but it differs in its leaves
heing nmch shorter, and its cones being without spines.
