is pubescent, leaves linear lanceolate, commonly 
entire, punctate beneath, flowers paniculate. 
All these disparities evince that this fine ano- 
malous and rare Grenus has been misunderstood 
and improperly described by nearly all the bot- 
anists. Now at last in 1836, the original Lin- 
nean and Kuhn’s plant having been found wild 
on the very identical spot, whence carried to 
Linneus, many specimens collected, of several 
varieties growing together, and roots, seeds and 
specimens sent to England by Dr. James 
Mease : the original species will become better 
known. Meantime I presume that the follow- 
ing comparative view of the Species actually 
known will be acceptable to the Botanists and 
Horticulturalists. 
These plants altho’ not very conspicuous, are 
not destitute of beauty, by their elegant shape 
and plumose seeds. They are all hardy peren- 
nials with thick roots ; they blossom in Sep- 
tember, and assume their feathery appearances 
in October.
