TETUAXDUIA MOXOGYMA 103 



Obs. This is undoubtedly nearly allied to the preceding; but sccir.s to be con- 

 stantly and sufficiently distinct. The leaves, moreover} so far as I have observed, 

 have not the siceet taste which characterizes the C. < ircazans.

 verging, peduncles frequently trichotomousj bracts ovate, or obovate, mostly ob-

Obs. Our plant lias longer 1 -aves t!i m the Kuropean sj>ecimens which I have 

 seen, — and the panicles are n •; finite s dense-flowered ; but 1 do not think it is en- 

 titled to be made a distin ; sj»e • s. As alrea iy mentioned, under No 6, 1 believe 

 this is the G. bermudiatium, or benn dense, of Muhlenberg's Herbarium; — but 

 probably not the plant to which that name was applied, by Linnaus. The root of 

 this species is also said to be v^cd, by the Aborigines, to dye a red color. Six or
