A slender tree fifty to a hundred feet high, and one to six feet in diameter. Leaves: in fives, blue-green, glaucous. Flowers: the staminate ones oval, yellow; the pistillate ones oblong, pale purple. Fruit: pendulous cones with thin scales.
The Mountain Pine is tall and slim, with spreading and somewhat drooping branches. • The bark on young trees is pale gray, and on mature trees is divided into square plates covered by small, flat, purple scales. The leaves are deep blue-green, and covered with a lovely bloom; while the long hanging cones are slightly thickened, and smoothed towards the top, and terminate in a small, prickly protuberance.
