LXXVII. CONI’FERE: PI'NUS. 973 
(fg. 1806.), in the White Knights specimen, 13 in. long, and .5, in, 
broad ; ovate, acuminate, concave on the sides, with a long point, 
as in P. Laricio; but reddish brown, and very resinous. Leaves 
(fig. 1807.) from 5in. to 6in. long, straight, stiff, and yellow at \\ 
the tip; sheath from $in. to lin. long, white, lacerated, and be- 
coming short and dark with age. Cone 2 in. long, and 11 in. broad, 
ovate-conical, brownish red, sessile, or with very short footstalks ; 
scales 2 in. long, and gin. broad. Seeds small; with the wings Sin. 
long. The leaves are thickly set, and inclined towards the shoot, 
and much lighter and more glaucous than in P. Laricio and its va- 
rieties, in which the foliage is of a darker green than it is in any [AVR 
other species of Pinus. The shoots are much more naked, the 
whole tree is more open and lighter, and the large and small 
branches are straighter and more distant, than in P. Laricio ; the 
plant is also of much less vigorous growth in British gardens. 
A large tree. Canada, near Lake St. John, and also in Nova Scotia and 
at Lake Superior; in dry sandy soils. Height, in America, 60 ft. to 70 ft. ; 
in England, 20 ft. to 30 ft. Introduced in 1756. It flowers in May, and 
the cones are ripened in the autumn of the second year.

The foliage and the cones, and even the tree altogether, bear a close general 
resemblance to P. Larfcio ; but the different form and colour of the scales, 
the lighter tinge of the foliage, and, above all, the much more delicate consti- 
tution of the tree, appear sufficient to justify us in retaining it as a distinct 
species. We are certain that the trees at White Knights are the true P. 
rubra of Michaux ; because they were raised by Messrs. Loddiges from seeds 
of P. ribra, sent to them by Bartram of Philadelphia. We have also, since 
the above was written, received cones and leaves from Mr. M‘Nab, jun., 
which were gathered by him in Upper Canada, in August, 1834, from trees 
which had been blown down, and which measured upwards of 70 ft. in length.
