 'Widow Kelley's' ranch on the San Francisco River," New Mexico. 



Range: Known only from type locality. 



A tree 9 to 15 meters high, the trunk 60 to 120 cm. in diameter; leaves in 3's, 

 yellowish green. 



This tree seems to have been first discovered in this same locality by Mr. Vernon 

 Bailey of the Biological Survey, U. S. Department of Agriculture, who made some 

 excellent photographs of it which we have seen. 



4. Juniperus scopulorum Sarg. Gard. & For. 10: 420. 1897.

Range: British Columbia and Alberta to Arizona and western Texas. 



New Mexico: Coolidge; Rivera; Santa Fe; Pecos; Cebolla; Las Vegas; Stinking 

 Lake; Mogollon Mountains; White Mountains. Open hills, in the Upper Sonoran 

 Zone, often extending into the lower part of the Transition. 



A beautiful though small tree, with dark green foliage and slender branches droop- 

 ing at the ends. The fruit is small, blue, and succulent. The Rocky Mountain 

 juniper occurs only in the higher mountains, associated sometimes with the common 

 cedar (Juniperus monosperma), more often with pines. When growing alone it takes 

 on a fine conical form with branches quite to the ground, rendering it an ideal tree 

 for lawns. 



5. Juniperus utahensis (Engelm.) Lemmon, Calif. Board For. Rep. 3: 183. 1890. 



Utah juniper.

New Mexico: Tunitcha Mountains; Aztec; Carrizo Mountains; Frisco; Dona Ana 

 Mountains. Open hills, in the Upper Sonoran Zone. 



A stiff, upright, much branched tree, coming into New Mexico from the northwest. 

 It differs from the next chiefly in the larger size and different color of its fruit. It 

 is probably much more common than the citations would indicate. 



6. Juniperus monosperma (Engelm.) Sarg. Silv. N. Amer. 10: 89. 1889. 



One-seeded juniper. 



Juniperus occidentalis monosperma Engelm. Trans. Acad. St. Louis 3: 590. 1877. 



Sabina monosperma Rydb. Bull. Torrey Club 32: 598. 1905. 



Type locality: "From Pikes Peak region of Colorado through west Texas and 

 New Mexico to Arizona and California." 



Range: Colorado to Nevada, south into Mexico. 



New Mexico: Common on foothills and high plains throughout the State. Upper 

 Sonoran Zone. 



This is the common juniper of the State. It is a low, much branched, frequently 

 very scraggy tree, 4 to 8 meters high. Under favorable conditions it assumes an 

 almost perfectly conical shape. The bark is gray and shreddy or stringy, the Leaves 

 of a rather yellowish green, and the fruit small and succulent. The wood does aol 

 decay readily ami is much used for fence posts. It will no doubl prove of value as a 

 decorative tree for lawns at elevations of from 1,800 to 2,250 meters, 



We arc unable to separate from this Juni/urus jilnclioti Sudworth. 1 Some of the 

 material from the eastern side of the State should belong to Hut Bpecies. Bo far as 



1 For. & irr. 13: 307. 1907. The type came from Paloduro Canyon in the Pan- 

 handle of Texas.
