A tree attaining in America GO feet in height and 15 feet in girth. 

 Bark unlike all other junipers, f to 4 inch thick, deeply divided into 

 small square scaly plates. Branchlets slender, angled, becoming terete 

 and scaly after the fall of the leaves. Leaves dimorphic ; on young 

 or vigorous branchlets acicular, spreading in three or in opposite 

 pairs I to \ inch long, tipped with slender cartilaginous points ; 

 upper surface concave, whitened ; lower surface greyish-green, keeled. 

 Adult foliage ; branchlets quadrangular ; leaves scale-like, in oppo- 

 site pairs, imbricated, closely appressed, about T V inch long, ovate, 

 obtuse, toothed in margin, with a depressed resin -gland on the 

 back. Leaves on the older branchlets tipped with a sharp point- 

 The juvenile leaves gradually pass into the adult foliage. 



Flowers dioecious. Fruit ripening in the second year, sub- 

 globose, nearly inch in diameter, sub-sessile, ebracteate, reddish- 

 brown, covered with a glaucous bloom, tuberculate on the surface, 

 with six to eight mucronate scales. Seeds four, angled, shining 

 brown. 



Juniperus pachyphlcea grows wild on arid mountain slopes at 

 4,000 to 6,000 feet elevation from South-Western Texas west- 

 ward along the desert ranges of New Mexico and Arizona, and 

 southwards into Mexico. It was discovered in 1851 by Dr. S. W. 

 Woodhouse in Eastern New Mexico. 



The date of introduction into cultivation is uncertain. The only 

 specimen known to exist in England, which is growing at Kew, 

 is 20 feet high, but has not yet produced flowers.

 Sargent from the Arnold Arboretum.
