a glaucous bloom, especially during the first season and then occasionally bluish in color, 

 with a thin skin closely investing the thick dry mealy flesh, and usually 4 seeds; seeds 

 acute or obtusely pointed, conspicuously ridged and gibbous on the back, with a thick 

 shell and 2 cotyledons. 



A tree, often oO-60 high, with a short trunk 3-5 in diameter^, long stout spreading 

 branches forming a broad-based pyramidal or ultimately a compact round-topped head, 

 and slender branchlets covered after the disappearance of the leaves with thin light red- 

 brown usually smooth close bark occasionally broken into large thin scales. Bark f '-4' 

 thick, on young stems reddish brown becoming on old trunks whitish, deeply fissured and 

 divided into nearly square plates 1'-%' long, and separating on the surface into small thin 

 closely appressed scales. Wood light, soft, not strong, brittle, close-grained, clear light 

 red often streaked with yellow, with thin nearly white sap wood; often producing vigorous 

 shoots from the base of the trunk or from the stumps of felled trees. 



Distribution. Dry arid mountain slopes usually at elevations of 4000-6000 above the 

 sea, from the Eagle and Limpio mountains in southwestern Texas, westward along the 

 desert ranges of New Mexico and Arizona, extending northward to the lower slopes of 

 many of the high mountains of northern Arizona, and southward into Mexico.

A tree, occasionally 60 high, with a tall straight trunk 2-3 in diameter, more often 

 not more than 20 in height, with a short trunk sometimes 10 in diameter, enormous 

 branches, spreading at nearly right angles and forming a broad low head, and stout 

 branchlets covered after the leaves fall with thin bright red-brown bark broken into loose 

 papery scales; frequently when growing on dry rocky slopes and toward the northern 

 limits of its range a shrub, with many short erect or semi-prostrate stems. Bark about
