524 LANDSCAPE GARDENING. 



P. Pyrenaica (Pyrenean pine). A very hardy, robust 



Syn . variety from the Pyrenees, perfectly hardy 



p. Hispanica. ^.j^ us having survived several winters ; 



P. Monspeliensis. -i- -r n 



p. laricio, and but. like P. nivea and P. Pallasiana, too 

 nine others. much resembling our native White pine to 



be very distinctive. 



P. radiata (Radiated-cone pine). This tree, from Upper 

 California, is one of Dr. Coulter's introductions, closely resem- 

 bling the P. insignis ; but, being a little denser and stouter, 

 may prove hardier. It seems to thrive near the sea-shore ; 

 the specimen found by Dr. Coulter being one hundred feet 

 high, with a straight stem, feathered to the ground. The wood 

 is much used at Monterey for boat-building. Not to our 

 knowledge introduced here yet. 



P. rigida (Stiff-leaved pine). Another of our "Native 



Syn. Americans," extending throughout the 



p. Canadensis-trifoiia. whole of the United States, as far north 



as Brunswick, in Maine. Not desirable, except to complete 



collections. 



P. resinosa (Red pine). An American tree, principally 

 Syn. found in Canada and Nova Scotia ; not very unlike 



p. rubra,&c. tne C ors i can . It abounds in resin, and is esteemed 

 for its strength and durability. 



P. Sabiniana (Sabine's pine). This majestic tree from the 

 Cordilleras of Mexico, where it grows to the height of one 

 hundred and fifty feet is very distinctive, and, we believe, will 

 prove hardy. Our trees have been out since the severe winters 

 of 1855-'56, arid stand in a protected place thus far very well. 

 The tone of the foliage is peculiarly soft and pleasing, being 

 of a light glaucous color. 



P. strobus (White or Weymouth pine). A description of this 

 well-known tree will be found in the first part of the book, under 

 Mr. Downing's section on evergreen trees. 



P. sylvestris (Scotch fir). This valuable variety is also too 

 well known to require description or even mention, beyond the 

 fact that, take it all in all, it is perhaps the most important of 

 all foreign pines. It is perfectly hardy everywhere in this 

 country, and in Europe, where it is cultivated under twenty 

 different names. It is not a beautiful tree, though it assumes,
