The Pacifictree is 20 to 40 feet high and from 6 to 20 inches in diameter; the trunk issh«n-t aiKl thickly set with hugely developed branches, except in very densestands. In its eastern range the tree attains a height of from 50 to 100 feet,and in close stands develops a smooth, clean trunk for from 30 to GO feet; from12 to 24 inches is the usual diameter. Taller and larger trees occur. Thefoliage of the coast tree is dark yellow-green, but away from the sea it becomesdistinctly a bright yellow-green, which is characteristic throughout the interiorPacific and eastern range. The leaves (fig. 15). regularly 2 in a bundle, are. Fio. i: -Phius coittorta: a, seed with and without wing from about 1 inch to nearly 3 inches long; usually about 2 inches long. Aseasons growth of leaves remains on the trees from six to eight years; longpersistence appears to belong more to young trees, on which leaves are retainedsometimes for nine years. The leaves of the Pacific form are only al)ont one-third as thick as those of the inland and eastern representative, which are nearlyan eighth of an inch wide. Cones (figs. 15,16) ripen late in August and Septem-ber. Very many trees open their cones in late fall and shed nearly all of theirseeds, while the cones of other trees in the same locality may remain closed fora number of years. Open or closed they adhere to thebranclies for a great manyyears, some of the closed ones finally opening and Iil)erating their seed.
