232 riNUS; or 



short footstalk. Scales, greatly elevated, and hooked back- 

 wards, very hard, and glossy, irregularly four-sided, broader 

 than long, and one inch wide, but much narrower and more 

 reflexed near the base, and straight-pointed near the summit. 



A small tree, from twenty to thirty feet high, with a dense, 

 ample head, found by Mr. Hartweg very sparingly on the 

 Ocotillo ]Mount, one of the highest points of the Angangueo 

 Mountains in Mexico. 



It is tolerably hardy in most parts, and a most beautiful kind, 

 on account of its fine, ample foliage.

Leaves, in fives, from three to four inches in length on the wild 

 specimens, and on young plants from four to five inches long, 

 rather stout, rigid, three-edged, and rough at the angles, thickly 

 set upon the young branches, and supported by long, sharp- 

 pointed, brown scales at the base of each sheath, of a dark green 

 on the upper surface, and slightly glaucous on the under side, 

 on the young leaves, but on old, full-grown leaves dark green 

 on both surfaces ; sheaths, persistent, or not falling off", nearly 

 half an inch in length, and rather rough or jagged on the ends. 

 Seed-leaves on the young plants from six to eight in number. 

 Branches, few, very irregular, rather stout, and twisted ; bark 

 very rough, particularly on the young wood, which is covered 

 with numerous long, broad, sharp-pointed scales ; buds, few, 

 imbricated, non-resinous, and rather lengthened. Cones, in 

 clusters of three or four together, but frequently single, nearly 

 horizontal, from four to five inches in length, and one inch and 

 three-quarters in the broadest part, which is near the middle,
