this tree are natives of the United States and Mexico. I 

 shall confine my remarks to those European species which 

 are most admired, and to one of those of our own country. 



Quercus robur> or English Royal Oaf:. This considerably 

 assimilates in appearance to our White Oak, and is con- 

 sidered as the finest timber tree of England. It is cele- 

 brated for living to a great age, and attaining to an immense 

 stature. Dr. Hunter mentions a tree of this kind then grow- 

 ing at Cowthorp, in Yorkshire, which measured 48 feet in 

 circumference, at three feet from the ground. Of such im- 

 mense importance is this tree, that it has been stated by 

 some authors, that the British nation owes to it its very ex- 

 istence as a nation. In that country, it is esteemed as one of 

 their finest ornamental trees; but here, where we have so 

 great a diversity of the same species, the English Oak is 

 seldom seen. It has one valuable quality as an ornamental 

 tree, it retains its verdure till January. 



Quercus Pedunculata, or Peduncted Oak. This resem- 

 bles the foregoing in foliage 2nd general appearance: the 

 principal difference is, that the fruit, or acorn, of the former, 

 is sessile; while on this it is supported by a long peduncle, 

 or footstalk, a distinction that I believe does not apply to any 

 of our native species, and which renders it quite a curiosity 

 the peduncle connected with the cup and acorn having 

 much the appearance of a pipe, such as is used for smoking. 

 There is a variety of this with variegated leaves. 



Quercus cerris, or Turkey Oak. This forms a tree of 

 middle stature ; the leaves are green on the upper surface, 

 and downy beneath; they are oblong, and so deeply indented, 

 as to appear somewhat lyre shaped ; the cup of the fruit is 

 small and prickly, and the acorn smaller than those of the 

 two preceding species. This is remarkable for holding its 

 fine foliage very late in the season. 



Quercus exoniensis^ or Luccombe Oak. This resembles 

 the preceding very considerably, but has the advantage of 

 being a sub-evergreen; and, when the winters are not too 

 severe, will hold the greater part of its foliage during that 

 season. 



Quercus ilex^ or Euro/lean Evergreen Oak. This, from 

 its perpetual verdure, is exceedingly well calculated for or- 

 namenting a shrubbery, and generally attains here to the sta- 

 ture of a small tree; the leaves much resemble those of the 

 Holly, whence it derives its specific appellation. Of this fine 

 evergreen there are numerous seedling varieties. I con-
