512 LANDSCAPE GARDENING. 



more, besides, which may possibly become acclimatized in a 

 few years. Six of these have already been described by Mr. 

 Downing, in his early editions, leaving a gain of eighteen new 

 varieties a great many for so valuable a genus, and in so short 

 a time as ten years. 



In our Southern States, the whole sixty varieties now known 

 abroad, could undoubtedly be grown with entire success; we 

 therefore propose, in describing the twenty-four varieties which 

 we have ourselves tested, to give some brief mention of the 

 most prominent and desirable of the others, which at the North 

 can only be cultivated in tubs, and kept in green-houses during 

 the winter. 



P. australis (Southern pine). This superb tree, more com- 

 St n monly known as the Georgia pine, is found from 



P. Palustris, Virginia to Georgia, growing to the height of 

 P. Georgica. s j x ty to seventy feet, with a bright green foliage* 

 nearly a foot long in young plants. We have great hope that 

 this tree may be acclimatized here. In Philadelphia, Mr. 

 Buist regards it as hardy ; at Elizabethtown it succeeds when 

 sheltered by evergreens, there being specimens there six feet 

 high. There is another variety, with much longer leaves, and 

 said to be much hardier, withstanding the coldest weather in 

 Germany, and coming from the northwest coast of America, 

 which would, no doubt, prove entirely hardy, since it was 

 raised, as we believe, from seed in Messrs. Booths' nurseries 

 at Hamburgh, where we remember we were informed peach 

 trees would not stand. 



P. Apulcensis (Apulco pine). This variety, from the val- 

 lies of Mexico, is likely to prove too tender for any but our 

 Southern States ; it reaches a height of forty to fifty feet. 



P. Ayacahnite (Ayacahnite pine). This pretty and effec- 

 tive pine, with a soft, vivid foliage, has been out with us. two or 

 three years, in a sheltered position, and seems tolerably hardy ; 

 it somewhat resembles our native White pine, only is much softer 

 and brighter. It is from the mountains of Mexico. 



P. Austiiaca (Austrian pine). This valuable tree, perfectly 



Syn. hardy everywhere, is found on the mountains in 



P So Austria > St yria, Transylvania, &c., and reaches a 



height of one hundred to one hundred and twenty
