ONE-LEAVED NUT PINE —Pinus monophyUa Torrey and Fremont An inhabitant of dr}', gravelly soils in the mountains of Utah, Nevada, Arizona, southern Cahfomia and adjacent Lower Cahfomia, at elevations of 1500 to 2300 meters, seldom attaining its maximum height of 15 meters, with a trunk diameter of 3 dm., its usual height being only about 7 m. The trunk is very short, often divided near the ground into several strong spread- ing branches; these are short and stout, forming a compact conic head, very old trees often hav- ing pendulous branches and are more round topped or irregular. The bark is about 18 mm. thick, deeply and irregu- larly fissured into nar- row flatfish confluent ridges with close dark reddish brown scales. The twigs are stout, light orange, finally be- coming dark brovwi. The branch-buds are ovoid, 6 mm. long, blunt, their scales light brown. The leaves are solitary and round, rarely 2 or 3 in a sheathless fascicle, triangular, pale green and glaucous, round and stout, about 4 cm. long, recurved at the apex, spinescent with a long hard tip, marked with 18 to 20 rows of stomata and containing 2 or 3 resin-ducts and one fibrovascular bundle, they are rather scattered along the twigs and per- sist for four to six years. The flowers appear in May, the staminate densely clustered near the apex of the twigs, oval or oblong, about
