64. PINUS TORREYANA

Spring-shoots uninodal, pruinose. Leaves in fascicles of 5, from 20 to 33 cm. long, very stout; resin-ducts medial, hypoderm uniform or somewhat multiform and of many cells. Conelets large, mucronate. Cones from 10 to 15 cm. long, on stout peduncles, broad-ovate, symmetrical, somewhat persistent; apophyses chocolate-brown, prominently pyramidal, the umbo salient and capped with a small mucro; seed-wing short, very thick, the dorsal surface of the nut spotted with the black remnants of the spermoderm.

A tree 10 or 12 metres high, often semi-prostrate in exposed positions, confined to a restricted area on the coast north of San Diego, California, and to the Island of Santa Rosa. This species resembles P. Sabiniana in the length of its seed-wing and in the color of its cone, but is distinct in the short triangular umbo, in its pentamerous leaf-fascicles and in the mottled dorsal surface of its nut.

65. PINUS SABINIANA

Spring-shoots multinodal, pruinose. Leaves in fascicles of 3, from 20 to 30 cm. long; resin-ducts medial, hypoderm multiform. Conelets large, their scales tapering to a sharp point. Cones from 15 to 25 cm. long, reflexed, ovate, slightly oblique, persistent; apophyses chocolate-brown, very prominent, the curved umbo confluent with the apophysis and with it forming a very large talon-like armature with a sharp apex and a broad thick base; seed-wing very thick, with a short membranous margin, the dorsal surface of the nut uniform in color.

A tree with sparse gray-green foliage, growing in small groves on the foot-hills of the Sierra Nevada and Coast Ranges of California. Its three leaves and the uniform color of the nut distinguish it from P. Torreyana. From P. Coulteri it differs in the length of the membranous portion of the seed-wing and in its gray-green leaves.
