short footstalks ; scales I'm. long, and 

 |- in. broad. Seeds small; with the 



wings 



Ions. The leaves are 



thickly set, and inclined towards the 

 shoot, and much lighter and more 

 glaucous than in P. Laricio and its 

 varieties, in which the foliage is of a 

 darker green than it is in any other 

 species of Pinus. The shoots are 

 much more naked, and the whole 

 tree is more open and lighter j and the 

 large and small branches are straighter 

 and more distant than in P. Laricio ; 

 the plant is also of much less vi- 

 gorous growth in British gardens. 

 The cones, in Michaux's figure, and 

 also on the trees at White Knights, 

 bear a good deal of resemblance to 

 those of P. Laricio ; which induced 

 Loiscleur Deslongchamps to consider 

 Michaux's plant as identical with that 

 species; but, we think, if he had seen 

 the cones and trees at White Knights, 

 he would have been of a different 

 opinion. We have sent him a speci- 

 men. We acknowledge, however, 

 that both 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 fo- 

 liage, and, above all, the much more delicate constitution 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. rubra, 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, 1 834, from trees which had been 

 blown down, and which measured up- 

 wards of 70 ft. in length. 



Description. A tree, according to Mi- 

 chaux, which, in America, rises from 70 ft. 

 to 80 ft., with a trunk about 2 ft. in dia- 

 meter, and retaining nearly the same bulk 

 for two thirds of its height. The bark is 

 of a clearer red than that of any other pine 

 in the United States; and by this the tree 

 may always readily be distinguished. The 

 leaves are 5 in. or 6 in. long, of a dark green, 

 two in a sheath, and collected in bunches 

 at the extremity of the branches, like those 

 of the pinaster ; instead of being distributed 

 regularly over them, like those of P. inops 

 and P. sylvestris. The female catkins are 

 of a dark blue, when they first appear;
