THE PIXE SUB-FAMILY. 



Its hardiness is yet uncertain, although -\ve are favorably 

 impressed with the experiments that hare fallen under our 

 notice. With us it proves successful, but we generally 

 place a slight protection of evergreen boughs around the 

 plant to shade it from the sun in winter. The color of 

 its foliage is that of a beautiful glaucous green, and con- 

 trasts agreeably with the darker hues in a group of pines. 

 The large cones, with their peculiar thick, recurved scales 

 and edible seeds, are also very interesting. This species 

 is quite remarkable for the copiousness of its resin. 



23. P, Jeffreyii, Sort. JEFFREY'S PIXE. Leaves, 8 

 inches long, from long, lacerated, persistent sheaths ; acute, 

 recurved, stout, dark green color. Cones, 8 inches long, 

 ovate-conical, clustered, with broad, projecting scales, 

 armed with very large, incurved spines ; seeds, quite large, 

 and handsomely striped. 



This beautiful new species is from Northern California, 

 where, according to Jeffrey, it inhabits poor, sandy soils, 

 and forms a majestic tree 150 feet in height. 



It resembles the P. ponderosa somewhat in general ap- 

 pearance, but has much more slender leaves. As regards 

 the. hardiness of this new candidate for popular favor, we 

 are pleased to be able to place it amongst those that 

 promise well. We have exposed it to the severity of sev- 

 eral winters, all of which it came through safely. But it 

 is proper to state that a more thorough trial is necessary 

 before it can be considered as perfectly reliable. 



The branches of this pine are slender, very spreading, 

 and of a pale, reddish-brown color; the buds are small, 

 and quite resinous. Like the most of our Californiau spe- 

 cies, it has large cones, which render it conspicuous, 

 being furnished with large, pyramidal, hooked scales.
