This is chiefly distinguished from Juniperus occidentalis by its smaller 

 globose fruits often monosperinous, its more slender branchlets, and the 

 absence of glands in the leaves. It is widely distributed over the 

 region east of the Rocky Mountains to the river Arkansas and western 

 Texas, spreading over the plateau of Colorado and southwards into 

 Arizona and New Mexico. It is probably not in cultivation in 

 Great Britain. 



Juniperus tetragona.

 Parlatore, D. C. Prodr. XVI. 419. J. occidentalis, var. conjungens, Engelniann 

 in Trans. St. Louis Acad. III. 590. J. Sabinioides, Sargent, Silva JT. Amer. X. 

 91, t. 523 (not Grisebach and Endlicher). Cupressus Sabinioides, Humboldt, 

 Bonpland and Kunth, Nov. Gen. et Sp. II. 3 (1815). 



This is distinguishable from J. occidentalis chiefly by its different 

 habit and its distinctly four-angled branchlets which suggested the name. 

 It is a more southern tree than J. occidentalis or J. monosperma; it 

 covers large areas in central Texas and spreads over the Mexican plateau 

 to near the city of Mexico where it was first discovered by Humboldt 

 at the beginning of the nineteenth century. 



Juniperus Oxycedrus. 



A dioecious spreading shrub, occasionally a low tree 9 12 feet high 

 with the trunk and primary branches covered with smooth reddish brown 

 bark. Branches numerous, erect or spreading; branchlets short and much 

 ramified, the youngest shoots angulate. Leaves homomorphic, persistent 

 two three years, in whorls of three, linear or linear-lanceolate, mucronate, 

 rigid and pungent, 0*25 0'5 inch long, obscurely bi-canaliculate, silvery 

 white with green median and marginal lines above, keeled and green 

 beneath. Staminate flowers axillary, globose, sub-sessile and bearing six 

 anthers. Fruits solitary, or two three together, sub-sessile or very 

 shortly stalked, spherical, variable in size, the largest somewhat more than 

 0*5 inch in diameter, reddish brown when ripe, composed of three 

 concrescent, apiculate scales that are distinguishable only at the apex of 

 the fruit where the outer margins are separated by a tripartite cleft.*
