BOTANICAL GEOGRAPHY.

of it. We do not know it thoroughly as yet, 
but what we know of it, is very peculiar. We 
may hope that Nuttali will describe it botani- 
cally. It has perhaps several divisions, the 
mountains, sea shores, and new Albion or new 
California to the South. It bears the same 
botanical relation to Sibiria than the Allegha- 
nies do to Europe. It is distinguished by pecu- 
liar trees, Firs, Oaks, Maples, the singular 
Garrya tree, many species of Ribes , Lupinns , 
Pentostemon , Cactus , Mimulus , &>c. with 
peculiar Genera Calochortus , Eutoca , Las- 
thenia , Collomia , Aegochloa , LeWisia , Clar~ 
kia , &/C. — The Labiate, Hypericines, Grasses, 
Fungi and Mosses appear to be scanty. Lili- 
aeea abound, but the Orchides are very few. 
The floral season extends from March to No- 
vember in New Albion, but is much shorter in 
the mountains and to the North. 
Besides the above great Regions of this Con- 
tinent, there are several other Local Regions, 
more confined in limits, but well distinguished 
by peculiar vegetation or growth of trees. The 
principal of these are 
1. The swampy pine region, where grow the 
Schubertia and Cupressus thyoides , from New 
Jersey to Louisiana, with many peculiar water 
plants. These swamps are unlike marshes by 
being sandy and having a clear yellow water. 
In the dry places prevail Pines, Hudsonia, &c. 
2. The Sandy Shore Regions all along the 
margin of our Sea from Long Island to Flori- 
da; Ilex and Myricas prevail, also shrubs, 
plants, with palms in the South. The rocky 
shores of the North are very unlike this. 
3. The Alpine Region or Summits of High 
mountains, where few trees are found, while
