246 PINUS, OR 



No. 15. Pinus muricata, D. Don, the Bishop's Pine, 



Syn. Pinus Edgariana, Hartweg. 

 Murrayana, Balfour. 



Leaves in twos, rather thickly set on the branches, from three 

 and a half to four inches in length on vigorous young plants, but 

 very much shorter on old ones, very stiff, rather broad, blunt- 

 pointed, hollow on the inner side, round on the outer, and of a 

 deep green colour. Sheaths rather short, smooth, and not more 

 than half an inch in length on the young leaves, and only slightly 

 persistent on the older ones. Seed-leaves on the young plants 

 in fives and rather short. Branches not very numerous, but 

 tolerably stout and rather irregular. Buds below the middle 

 size, imbricated, much pointed, and destitute of resinous matter. 

 Cones in clusters, of from four to seven, in whorls round the 

 stem, reddish brown when young, but changing to a gray or 

 ash colour when old ; rather pendulous, and nearly straight or 

 very slightly incurved on the side next the branch ; three 

 inches in length, and one and a half broad near the base, which 

 is- the widest part, and tapering to rather a blunt point ; the 

 base is slightly uneven, and the cones, which are sessile, or nearly 

 so, remain on the tree for years. Scales largest on the outer side 

 of the cone, particularly those towards the base, where they 

 are conical, nearly straight or slightly bent backwards, much 

 elongated, pointed, and half an inch in length ; the scales on 

 the inner side of the cone and at the point are much the 

 smallest, quadrangular, and nearly Hat, except those near the 

 point, which are rather more elevated than the others, with a 

 slight ridge running across their middle, terminated by a short, 

 straight, broad prickle in the centre ; each cone contains from 

 nine to ten rows of scales, within each of which are two very 

 small, dark-brown seeds, with wings half an inch long. 



This very distinct Pine was first discovered by Dr. Coulter, 

 at San Luis Obispo in Upper California, to the south of Mon- 

 terey, at an elevation of 3000 feet, and within ten miles of the 

 sea-shore. It grows straight, but rather stunted, seldom exceed-
