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- 
s monly known as the Georgia pine, is found from 
P. Paiustris, Virginia to Georgia, growing to the height of 
P. Georgica. s i 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, ftnly is much softer 
and brighter. It is from the mountains of Mexico. 
P. Austriaca (Austrian pine). — This valuable tree, perfectly 
SyJl ' hardy everywhere, is found on the mountains in 
P. nigra, Austria, Styria, Transylvania, &c., and reaches a 
P. lancio. height of one hundred to one hundred and twenty
