is pubescent, leaves linear lanceolate, commonly 

 entire, punctate beneath, flowers paniculate. 



All these disparities evince that this fine ano- 

 malous and rare Genus has been misunderstood 

 and improperly described by nearly all the bot- 

 anists. Now at last in 1830, 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 appearance 

 in October.

 bres, lower leaves trinerve, subpetiolate or base 

 attenuated, 1 or 2 inches long, a few are oppo-

 cence by some ; perianthe striate glandular,
