224 PINUS ; oil 



No. 67. PiNUS F.i.EXiLis, Torrey^ the Contorted-branched Pine. 



Leaves, in fives, but sometimes in twos, threes, fours, and 

 fives, on the same branch ; short, stout, rigid, curved, blunt- 

 pointed, quite entire, stoutly keeled on the inner face, rounded 

 on the outer, and from two to three inches long on the adult 

 plants. Sheaths, composed of numerous, long, membranaceous, 

 loose scales, which soon fall off" and leave the base of the leaves 

 naked. Branches, horizontal, very stout, and much contorted. 

 Cones, ovate, rounded at the base, two inches and three quarters 

 long, and nearly two inches in diameter at the widest part, and 

 full of resinous matter. Scales, projecting into a thickened 

 pyramidal elevation, transversely keeled, and terminating in a 

 short, broad, incurved scar. Seeds, large, oval, and wingless. 



A small tree, growing from thirty to forty feet high in Nor- 

 thern Mexico and California. 



Mr. Jeff"rey found it on the summit of a mountain near Fort 

 Hope, on Eraser's E,iver, and on the Shasta Mountains, growing 

 on granite rock, where the soil is scant. It is most abundant 

 at an elevation of from 8,000 to 9,000 feet, but ascends to 

 14,000 feet ; at its lowest elevation, when first it makes its 

 appearance on the mountains, it is a small tree forty feet high 

 and one foot in diameter, with a wide spreading top, the branches 

 being very stout, and much contorted, but dwindling down to 

 a small shrub, on the iipper part of the range not more than 

 three feet high, of a tabular form, and so compact that a person 

 could walk along the top of it. 



No. 68. PiNUS GoRDOx lANA, Hurtweg, Gordon's Mexican Pine. 



Leaves, in fives, sixteen inches long, rather slender, three- 

 edged, very dense, light green, and longer than any of the other 

 kinds. Sheaths, persistent, or not shedding, about one inch and 

 a quarter in length, rather rough, and scaly. Seed-leaves, on 

 the young plants mostly seven in number, and rather short. 

 Branches, rather numerous, at regular distances, slightly ele- 

 vated at the points, and not very robust ; buds, very scaly, non- 

 resinous, and of a moderate size ; male flowers, rather large.
