{fg. 1806.), in the White Knights specimen, H in. long, and ^in. 

 broad ; ovate, acuminate, concave on the sides, with a long point, 

 as in P. Laricio ; but reddish brown, and very resinous. Leaves 

 (fg. 1807.) from Sin. to 6 in. long, straight, stiff, and yellow at 

 the tip; sheath from ^in. to 1 in. long, white, lacerated, and be- 

 coming short and dark with age. Cone 2 in. long, and 1^ in. broad, 

 ovate-conical, brownish red, sessile, or with very short footstalks ; 

 scales X in. long, and fin. broad. Seeds small ; with the wings ^in. 

 long. Tlie 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 

 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. Laricio ; 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 tlie 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, ISS-t, from trees 

 which had been blown down, and which measured upwards of 70 ft. in length.
