218 CONIFERS COLLECTED IN UPPEE CALU'tm.NlA. 



San Luis Obispo, in Upper California, to tiie south of Monterey, 

 in lat. Su", at an elevation of 3000 feet, and within ten miles of 

 the sea shore. It grows straight, but rather stunted, seldom 

 exceeding 40 feet in height. Mr. Hartweg found it growing on 

 the western declivity of the mountains near Monterey, and within 

 two miles of the sea shore, attaining a height of from 20 to 30 

 feet, and witli a trunk 12 inches in diameter. In this locality 

 it was confined to a small wood ^ a mile square, and intermixed 

 with and surrounded by Finns insignis. Mr. Ilartweg again 

 met with it a considerable distance to the south of Monterey, on 

 the ascent to the Mission of La Purissima, where the monotony 

 of the bare hills was only relieved by a small forest of it ; the 

 trees, however, not attaining a larger size than those found 

 growing near Monterey. 



Tliis pine Mr. Hartweg supposed to be new, and accordingly 

 gave it the name of Pinus Edgariana ; but, as it had previously 

 been named and described by Professor Don in the Linnean Trans- 

 actions, as above quoted, 1 am obliged to cancel Mr. Hartweg's 

 name. It is the " Obispo," or Bishop Pine of the Californians ; 

 and no doubt will prove quite hardy.

Leaves in threes, thickly set on the branches, bright green, 

 rather stiff, broad and ilat, with an elevated rib running along 

 their middle on the inner side, 4i to 5 inches in length on the 

 wild specimens. Slieaths short, smooth, not moi"e than half an 

 inch long on the young leaves, very much shorter on tlie older 

 ones, and only partially persistent. Seed-leaves on the young 

 plants from seven to eight in number, rather slender, and not

 roughish bark. Buds below the middle size, imbricated, and 

 not very resinous or pointed. Cones mostly in clusters of four, 

 but sometimes solitary or in pairs, and only produced on the 

 main stem, of a long conical shape, 5 inches in length and 2 

 broad, the outer surface curved, the inner straight, widest near 

 the base, and gradually tapering to the point, quite sessile, and 

 uneven-sided at the base, very hard, of a light brown colour or 

 silvery gray when old, verj' glossy and full of resinous matter ; 

 they stand off at nearly right angles when old, although ratlier 

 pendulous when yovmg, and remain on the trees for years without 

 even opening or shedding their seeds. Scales largest and most 

 developed at the external base and down three parts of the outer
