Darlington. It is probable that it does not occur very far to the 
north.

description of Walter can hardly be improved as respects the 
prominent features of this very distinct species. Michaux has 
apparently described it under the name of Agrostis dispar; hav- 
ing detected (it would seem) two pale. I have observed in 
the New Hampshire plant, in a single instance, a membranaceous 
development at the inner base of the (inferior) palea, from which 
the bristles usually found on each side of the orifice of the palea, 
seemed to arise. These bristles, it may be remarked, occur in 
every American Trichodium ; though from the generic character 
of Michaux, and the silence of other authors, we might suppose 
they were wanting. The variety ?. above mentioned, is perhaps 
a distinct species, but I could not distinguish its florets from those 
of «. under the microscope. It is a coarse, green scabrous, rather
