it must be distinct from the true P. contorta of the coast, which has a resinous, hard wood, like P. sylvestris ; but 
I confess that, with the exception of the breadth of the leaves, I find no other botanical characters to distinguish the 
two. Well grown cones of Murrayana are nearly symmetrical, ies are more or less oblique, like those of true 
contorta. —[Mar. 17, 1883.]

ABIES SUBALPINA, Eng. n. sp. Tall and slim, 80 to 100 feet high, often 50 feet without branches ; bark [555] 
smooth, white, and covered with vesicles to near the base ; leaves 6 to 12 lines long, less than a line broad, not 
twisted near the base, bisulcate and somewhat glaucous on the lower (outer) side, short-pointed, obtuse or slightly 
einarginate, those on the lower branches 2-ranked and spreading, those on the upper scattered, crowded, and more or 
less appressed, shorter on fertile than on sterile branchlets ; ; cones 24 to 3 ng long, 13 to 2 inches thick, solitary, 
erect, ovate or oblong, obtuse, aaa scales 6 to 10 lines long and about as broad, horizontal and close-pressed, 
broad-cuneate, unguiculate ; the rounded upper margin somewhat ‘reflexed and resinous, pubescent ; bracts short, white 
with a dark base, erose-dentate all ea their slightly elevated summits furnished with a strong mucro ; seeds large, 
the wing covering nearly the whole surface of the scale ; sterile aments 2 inches long, 3 lines in diameter, marked longi- 
tudinally and paid, Sasi by the dark centres of the otherwise light brown mucronate scales. — American

UGA CAROLINIANA, n. sp. A small tree of the southern Alleghany Mountains with larger (6-8 lines [223] 
Sik. _ line wide), darker leaves than the common hemlock spruce, retuse or often notched at tip, without 
stomata above, beneath with two pale bands, each with 7 or 8 series of stomata ; strengthening cells under the epidermis 
on keel, midrib, and edges; cones 12-14 lines long, scales oblong, much longer than wide, in =; order, spreading at 
right angles after maturity, broad bracts slightly and obtusely st ; sectis (2 lines ee g) Ww ith numerous (15-20) 
small oil vesicles on the under side, twice sian than wing. 
tains of North and South Carolina, on dry slopes and ridges. —Smaller, stouter branched than T. Canadensis, 
from which it is always readily distinguished by its larger cones with wide-spreading scales. It was first noticed in the 
mountains of South Carolina by Prof. L. R. Gibbes of Charleston in 1850, who sent specimens to Prof. A. Gray 
in 1856, and in an acconipanying letter suggested for it the name of Pinus laxa; he obtained it from both Caro- [224] 
linas. Prof. Gray himself had already eollaasea it in 1842 on Bluff Mountain, N. C., in foliage only ; and last 
year Mr. A. H. Curtiss again met with it “on Pinnacle Mountain, N. C., a long ridge commencing about 8 miles 
south of Hendersonville, probably 3,000-4,900 feet high, where in groups of only few trees it ps das a > ay the 
summit, and even cliffs, while 7. Canadensis abounds in the ravines of the same region ; bot cl side 
by side at the entrance of Mr. Middleton’s place at Flat Rock, 3 miles from Hendersonville, whee their branches inter- 
lock and their differences are strongly exhibited.” I have not seen any young shoots of this species, and therefore cannot 
say whether their leaves are spinulose-denticulate, as they are in young plants of the two other North American species. 
These may be distinguished thus ;: — 
T. CanapDEnsIs : leaves of the mature tree smaller (4-7 lines long), obtuse with 5 or 6 series of stomata on each 
side of the keel below, destitute of any strengthening cells; scales of cone in & order, orbicular-oblong with broad 
truncate bracts ; wing very broad at base, tapering, scarcely longer than the seed which shows 2-3 large oil vesicles, 
T. Mertenstana has larger leaves, with two bands each of 7-9 series of stomata ; strengthening cells few on the 
edges and very sparse on upper and lower side of leaf ; cones 6-12 lines long (not 13 inches, as sometimes stated), scales 
oblong, mostly a little narrowed in the middle, bracts slightly cuspidate ; seeds smaller with few oil vesicles, wings 
twice as long as the body of the seed. — 1881, vol. vi. 
A few remarks by Engelmann on Abies Fraseri and A. balsamea, entitled “ Notes on the Coni- 
feree,” will be found in the proceedings of the Philadelphia Academy for Sept. 19, 1876, pp. 173-175, 
and in “ Gardener's Monthly,” 1877, vol. xix., p. 308. Their substance is contained in the descriptions 
of these species above. — Eps.
