Page 11 - The extreme age attained by this species has not yet been determined, but it is probably as long lived as Arizona cypress. The largest trees found so far are at least 200 or 250 years old.
Page 16 - VIII, b, c, d). Seed-leaves, two in number, are needlelike, sharp pointed, and about an inch long. Seedling leaves are similar in form, but much shorter, spreading in groups of three at close intervals. The leaves produced in subsequent years are successively shorter and closer in their arrangement, until about the third or fourth year, when a few twigs bear leaves of adult form. The wood of western juniper is pale brown, tinged with red, with a slight aromatic odor, very narrow-ringed, and, like...

Page 9 - ... in practically every case there is a comparatively large resin gland, a characteristic which distinguishes the leaves from those of Arizona cypress. Young shoots bear closely pressed leaves from one-fourth to one-half of an inch long, with very keen and more or less spreading points (PI.
Page 29 - It grows in the driest rocky and gravelly soils on mountain slopes, plateaus, and canyon sides, where it is likely to be much stunted and distorted. The best developed trees are found in moist, deep washed soils of canyon bottoms and in protected places on the lower mountain benches. The tree's vertical range extends from about 4,500 to nearly 8,400 feet elevation, but it is most abundant between 5,50O and 7,000 feet.

In diameter they range from seven-eighths to one-eighth of an inch, and are composed of from 6 to 8 2 scales, armed with large incurved, somewhat flatpointed bosses. The mature cones are smooth, but conspicuously wrinkled, and covered with a deep blue-gray bloom, which when rubbed off reveals a rich dark-brown color beneath. Very old cones (PI. IV, a) are ashy-gray, with bosses much less conspicuous 3 than in newly matured cones (PI.
Page 18 - J. occidental's, while specimens shown at the Centennial Exposition in 1876 were described as J. virginiana var. montana Vasey.4 Prof. CS Sargent 5 distinguished the tree from J. virginiana in 1897 and named it J. scopulorum. A noteworthy fact is, however, that in 1876 Dr. George Vasey, the first botanist of the United States Department of Agriculture, gave to this tree the distinct common name "Rocky Mountain red cedar," e and also pointed out the fundamental differences between its crown form and...
Page 14 - VII). The soft flesh of the ripe fruit is dry, resinous-aromatic, and sweet, and sometimes contains one, but, commonly, from two to four hard, bony seeds. Birds and mammals eat the berries greedily and thus assist in disseminating the seed ; otherwise the fruit may remain on the branches during the following winter or spring, occasionally even until late summer, before falling to the ground.

His recognition of these distinctions would seem to show that Dr. Vasey was really the first author to separate this tree from its eastern relative and but for his unfortunate use of a preoccupied name ("var.
