ADDITION TO THE OAKS.

enough for the passage of a hair : it is strong hut not durable, and is the 
last among the Oaks to be employed in building. Its principal use is for 
staves, which, at home, are used to contain salted provisions, flour and 
such dry wares as are exported to the islands, and in the colonies, to 
receive mêlasses and sugar. 
The bark consists of a very thin epidermis and a very thick cellular 
tissue. It is extensively used in tanning, but is less esteemed than that of 
the Spanish, Black and Rock Chesnut Oaks. 
The Red Oak was one of the earliest American trees introduced into 
Europe. Large stocks are found on the estate of Duhamel, which yield 
seed abundantly, and even multiply naturally ; but the quality of its wood 
is so inferior, that I cannot recommend its propagation in our forests.

ADDITIONS TO THE OAKS. 
In the Flora Âmericœ Septentinonalis, of Pursh, published in England 
in 1814, the following species of Oak are added to those which I have 
described : 
Quercus MARiTiMA. Q. folUs perennünUhus, coriaceis, integerrimis^ glabris, basi 
attenuatis, apice mucronatis ; ciipulâ scutellatâ ; glande subrotundà. 
A shrub from 3 to 8 feet high, found on the sea-coast in Virginia and 
Carolina : I consider it as a variety of the Willow Oak, Quercus phellos. 
Quercus myrtifolia. Q. foliis pere7inantibus, coriaceis, oblongis, integerrimis, 
glabris, utrinque acutis, supra nitidis, margine revolutis. 
This species, of which Mr. Pursh appears to have seen neither the blos- 
soms nor the acorns, escaped my researches ; perhaps it is the variety of 
the Water Oak which I found among the Live Oaks, and which preserves 
its leaves for three or four years. 
Quercus hemisphærica. Q. foliis perennantibus, oblong o-lanceolatis, trilobis sinu- 
atisque, lobis mucronatis, utrinque glabris. Willd.
