CONCLUSION. 
In the present Work there are several species not enumerated, some 
being of doubtful origin, and others so exceedingly rare as scarcely to 
be procured: they are mentioned briefly in the addenda. At the con- 
clusion of this Work the author intended to have commenced a Natural 
History of those Foreign Grasses that were remarkable for their beauty, 
singularity, or economic values; this latter Work, however, will be 
deferred, as the author cannot devote the time requisite for this un- 
dertaking at the present moment. In order to distinguish the species 
of British Grasses, the author has appended a
