Of the four species of red cedars known in Colorado three are 
' sometimes trees of small or medium size. The characters which 
separate them are not easily recognized except by botanists. 
The Utah red cedar (Sabina utahensis) is a bushy tree seldom more 
than twenty feet high, which occurs in the desert region between thie Rocky 
and Sierra Nevada MountaJins. It is found in the western parts of this state 
on dry mountain slopes and tablelands. It is locally used for fuel and fencing 
and the fruit, which is a rather dry, sweet berry, is used for food by the 
Indians, either fresh or (ground and baked into cakes. 
The single-seeded red cedar (Sabina monosperma) occasionally 
reaches a stature of forty to fifty feet in favorable locations. It occurs along 
the eastern base of the Rocky Mountains in the southern half of Colorado 
and extends to western Texas, over the mountain ranges of Nevada and into 
Mexico. It is often associated in southern Colorado and Utah with the 
pinon pine. 
It is usually an irregular, open-tieaded tree, with red-brown bark on 
the naked branchlets and thin, grayish, scaly or shreddy bark on the trunks. 
The fruit is about one-eighth to one-fourth inch long, black with; a whitish 
bloom and contains usually one or rarely two or three grooved seeds. The 
wood and fruit of this species are used for the same purposes as in the pre¬ 
ceding species. 
The Rocky Mountain Red Cedar (Sabina scopulorum) (Plate VIII 1.) 
is widely distributed throughout the northwestern portions of the United 
States, from the ©astern foothills of the Rocky Mountains to the coast of 
British Columbia and Washington, and from Alberta to western Texas and 
northern Arizona. It frequents the foothills and river bluffs and is our com¬ 
mon red cedar in most parts of Colorado. It reaches a height of thirty to 
forty feet, when favorably situated, and forms an Irregular round topped 
head. 
The berries are 'bluish black with a bloom and contaiin one or two bony- 
shelled, grooved seeds. The fruit is usually somewhat larger than that of 
the preceding species and ripens at the end of the second season* 
The red cedars, on account of their very fine foliage and 
branchlets, may be effectively used among other evergreens to give 
variety to the planting. Their foliage is usually somewhat grayish 
in winter. Although of slow growth their hardiness and the fact 
that they bear pruning well fits the red cedars for use in forming 
hedges and windbreaks.
