CONIFERZ: PINE FAMILY. 























1—WdolITE PINE. “ MOUNTAIN PINE.” (Pinus monticola, Douglas.) 
A large and important timber tree, occurring in northern Montana 
and Idaho (also in southern British Columbia, and from Washington 
Territory to southern California) between 3,000 and 10,000 feet eleva- 
tion, usually occurring on a poor, sandy soil. In northern Montana it 
attains, perhaps its most valuable size, 60 to 100 feet high and over 3 
feet in diameter. The wood is quite similar to that of the White Pine 
of the Northeast (Pinus strobus, Linn.), and is 3s used considerably for 
— lumber throughout its range. 
Description.—Leaves in fives (with small distant teeth) often 3 to 4 inches long. 
- Cones 5 to 8 inches long (on long stems), slender, cylindrical, yellowish-brown ; pend- 
_ ulous the second year; seeds small, light-colored. Bark pale, rather smooth, ‘irewte 
_ ing up intosquarish plates. (Distinguished from Pinus strobus by its longer cones 
and stiffer leaves. ) ; 
2—Wurre Pine. (Pinus flevilis, James.) 
Next to the Bull Pine (No. 7) in its general distribution, on dry, rocky, 
ridges ; and, although its wood is inferior to that of the former, it is 
‘used for many of the same purposes; in parts of Wyoming and Mon- 
tana furnishing most of the local supply of lumber for domestic pur- 
{ poses. Generally found growing on eastern slopes at altitudes from 
4,000 to 10,000 feet, from Montana (probably much farther north) to 
- New Mexico; (also in the Guadalupe and Limpia Mountains, western 
- Texas; the high ranges of Utah, Nevada, northern Arizona, and in the 
Inyo Mountains and Mount Silliman, California.) It attains a height 
of 50 to 75 feet, with a diameter of 3 feet and over. 
| Description.—Leaves in fives, 1} to 2 (exceptionally 24 to 3) inches long. Cones on 
very short stems, oval or rather cylindrical, 3 to 5 inches long and light brown; 
Seales spreading widely at maturity. Crown roundish; branches drooping; bark 
furrowed and gray. 
—38.—TOARY-BRANCHED PINE. (Pinus albicaulis, Engelm.) 
A tree of little economical importance, as it rarely attains a useful 
Size. It has a limited range in the Rocky Mountain region, occurring 
only on high ridges in northern Montana (but on the Pacific coast ex- 
tends from southern California to British Columbia). It grows in dry, 
gravelly soil, reaching up to the extreme line of timber growth, where 
‘it becomes ashrub; sometimes 40 feet in height and 1 to 14 feet in 
diameter, though generally smaller where it occurs ,in greatest abun- 
dance. Wood light and soft.
