The cones, which are early deciduous, are ovoid, 2 to cm. long and brown, their scales obovate, rounded and entire or slightly wrinkled on the margins; bracts 2 mm. long or less, with angled, acute erose tips; seeds about 3 mm. long, the wing obovate, light brown, shining. This species has been confused with Picea canadensis, which has smaller sterigmata and longer and narrower cones. 5. ENGELMANN'S SPRUCE — Picea Engelmanni (Parry) Engelmann Abies Engelmanni Parry. Picea Columbiana Lemmon Engelmann's spruce ranges from British Columbia to Oregon, east to Alberta, and south through the Rocky Mountains to northern New Mexico and Arizona, sometimes forming great forests and attaining a maximum height of about 45 meters with a tnmk diameter of m. The branches are slender and spreading in close whorls, forming a compact narrow cone; on old forest trees the branches disappear for a con- siderable height, leaving a short narrow dense conic head. The bark is up to 15 mm. thick and deeply furrowed, red-brown to purpUsh brown. The twigs are rather stout, somewhat hairy, greenish yellow, gradually becom- ing dark yellow-brown. The win- ter buds are conic, rather blunt, covered by pale brown thin-edged scales. The leaves, which emit a polecat-like odor when bruised, are 2 to cm. long, slender, soft, and flexible, sharply thick- 11 imw^^T^"^^^^^^^ ^ "S" tipped, marked with several rows ^ of stomata on each face, pale bluish green when young, darker w
