PART III.

Description. A straight middle-sized tree, about 40 ft. high. Conesin clusters (2 or 3), unequally-sided, ovate, about 3in. long; scales wedge-shaped, very thick; dilated at the apex, obsoletely 4-angled, mucronated withan elevated umbilicus; elongated at the external base, compressed on bothsides, callous, rigid, smooth, shining, recurved, and spreading. (D. Don.) Anative of California, at San Luis, where it is called Obispo (the bishop),growing at the height of 3000 ft. above the level of the sea. Professor Doninforms us that the cones grow 2 or 3 together ; and adds, that he had notseen the leaves of this, or of P. tuberculata and P. radiata, but that he thinksit is probable that, like the greater part of the American pines, they growin threes.” {Lin. Trans, and Lamb. Pin.)
