OBSERVATIONS ON THE OAKS. 
Quercus maritima, (the Maritime Oak.) The fruit of 
this species, and sometimes the leaves approach to the 
Willow Oak, but this is a low shrubby plant of the 
Southern States, with sempervirent leaves, which are 
very often deeply and distinctly sinuated, rigid, with 
the lobes often obtuse and mucronate. 
Quercus myrtifolia, (Myrtle-leaved Oak.) Of this 
elegant and curious species, we have yet no materials 
deserving of a figure. 
Quercus stellata. Q. obtusiloba, Mich. (Post Oak.) 
The variety which I mentioned in the Genera of North 
American plants, vol. 2, p. 215, under the name of /3. 
depressa , rarely exceeds 3 feet in height, and bears 
acorns at the height of 12 to 18 inches from the ground. 
I first observed it on the hills of the Missouri, up to its 
confluence with the river Platte, and it is also almost the 
last species which we find to the westward. I have 
since met with apparently the same low variety on the 
gravelly poor hills of the island of Martha’s Vineyard, 
near Massachusetts Bay; it is this scrubby growth of 
Oak which still affords shelter to the grouse on that 
island. In some parts of Massachusetts, (according to 
Dr. Emerson,) the usual large growth of this tree is 
occasionally met with. The species of Quercus which 
I called Q. Michauxii , is, I now believe, nothing more 
than a mere variety of Q. prinus. 
Swamp White Oak, (Quercus bicolor.) Of this spe-
