Bristle-cone us aristata Engelmann. DISTINGUISHIXC; CHARACTERISTICS. Bristle-cone pine, an alpine species, and only a straggler in the Pacific country,is known in the field as fox-tail pine and hickory pine. I)ut since these FOREST TREES OF THE PACIFIC SLOPE. names are applied also to other species it is hoped that the more appropriateuame, Iiristle-coue pine. may replace them. The trunk is usually short,. f Fig. 10.—Pintis aristafn: a, seed. from to .50 feet hi^h and from 12 to 18 inches in diameter, with a ratherwide, bushy crown of long, irregularly upright top limbs, and shorter, drooping FOREST TREES OF THE PACIFIC SLOPE. 39 lower ones. Somewhat larger occasionally. The bark of old trunks is a dullreddish brown and is rather shallowly furrowed, the main flat ridges irregu-larly connected by narrower slanting divisions, whereas the limbs, as well asthe trunks of small trees, are smooth and chalky-white. The deep green foliageis densely clustered at the ends of the twigs, the needles seeming to be presseddown ; in this respect closely resembling the true fox-tail pine. Five leaves,about 1^ to IJ inches long, are borne in a cluster (fig. 10). Leaves of eachseasons growth persist approximately twelve to foiuteen years. Ripe cones,matured at the end of the second season, are from 2^ to about 34 inches long,deep chocolate brown with a purplish ti
