150 CONIFEROUS TREES 



P. pseudo-Strobus, Lindley. Mountains of 

 Mexico. — Not hardy unless in very warm and 

 maritime districts. It is a handsome species of 

 large and spreading growth, not unlike P. Strobus, 

 but more silvery in appearance. 



P. PUNGENS, Lambert. Virginia, Carolina, and 

 Pennsylvania. 1804. — The whole contour of this 

 tree is irregularly spreading, with pale yellowish 

 green leaves, each 2 J inches long, placed thickly 

 on the branches. The cones give a very unusual 

 as well as formidable appearance to the trees, 

 these being yellowish brown, and arranged in 

 whorls around both stem and branches. They 

 are without foot-stalks, 4 inches long, by 3 inches 

 diameter at the base, and tapering quickly to a 

 sharp point. The scales are hooked. At only a 

 few stations in this country have I known P, 

 pungens to do at all well. 



P. PYRENAICA, Carriere. (Synonyms : P. 

 Brutia, Tenore ; P. Loiseleuriana, Carriere.) 

 Mountains of Southern Europe, Asia Minor, the 

 Levant, etc. 1834. — As seen generally in this 

 country, the present species cannot be ranked as 

 ornamental, while it is frequently confused with 

 the totally distinct and far more valuable P. 

 Laricio pyrenaica. The largest specimens of the 

 true P. pyrenaica that I have seen, and from which 

 these notes were taken, are growing on the 

 Churchhill property, in the north of Ireland. They 

 are of untidy, informal appearance, with long and 

 lithe branches, deep green, wavy leaves, ^\ inches 

 long, and smoothish oblong cones, the scales of 

 which do not project much beyond the general 

 outline. By the sea-coast it does well, and puts
