pecially at the north, and the consequent paucity of truly alpine 
or even subalpine species. We have an alpi ion inde 
ern part of New England and New York, between or near lat. 
44° and 45°. The White Mountains of New Hampshire fur- 
nish far the larger part, viz., the range strictly so called, with 
six or seven square miles (taken horizontally) of alpine region, 
of which the highest point slightly exceeds 6200 feet in eleva- 
tion, and its lower limit is about 4500 feet above the level of 
the sea, and Mount Lafayette (reaching to 5200 feet) along with 
other smaller patches, together making up almost as much more. 
Mount Katahdin in Maine (about 5300 feet high) may furnish a 
square mile or so of alpine region. The Green Mountains of 
Vermont (with a maximum elevation of 4360 feet) present mere 
vestiges of alpine vegetation in one or two places; and two or 
three summits of the Adirondack Mountains of northeastern 
New York (with a maximum elevation said to exceed 5400) are» 
of a more decidedly alpine character, but apparently of small 
extent and far from rich in species. 
The southern shore of Lake Superior affords no alpine and 
perhaps no strictly subalpine species; nor do any occur in the 
anerogamia and highest Cryptogamia: and although very 
much still remains to be done, yet we are now in condition 
profitably to compare our vegetation with that of Europe, and 
also, though less critically, with that of other parts of the north- 
ern temperate zone. ee 
The following tables exhibit the principal elements of our 
flora, and some of its relations to the Kuropean, &c. aie 
* The White Top Mountain in Virginia, just within its southern boundary, is eom- 
Siiay said to be about 6000 feet in elevation; but this is probably an exaggeration.
