erect grass, with somewhat broad leaves and large florets. The 
name given by Walter, the discoverer of this species, is the old- 
est, and, it would seem, very appropriate. |

York, in woods, common, Torrey; New Hampshire, in moun- 
tain forests ; (6. a small delicate form with a very slender pani- 
cle,) rocks of the Flume, Lincoln, N. H. This and the last 
were not considered by Michaux as belonging to Trichodium ; 
and Willdenow describes the present species as possessing two 
paleze. Our plant is always distinguishable by its elegantly flex- 
uous and spreading many-branched panicle, and erect habit.

Gray.
