 it neither belongs to Galea as I have proposed to limit it, 

 nor to any of the genera hitherto confounded with it. 



M. Poiret, in the Supplement to the Botanical Dictionary 

 of the Encyclopedic Methodique, has under the article 

 Calea retained all the species of this genus given by Persoon ; 

 and also Calea asp era ; which, however, he has in a sub- 

 sequent article correctly referred to Melananthera. 



Connected with the proper subject of this paper, I shall 

 describe and add some observations on a plant lately sent 

 from Brazil by Mr. Sellow ; which, though not strictly refer- 

 able to Composite, probably belongs to a genus at present 

 included in this family ; and conclude with a few remarks 

 on the structure and affinities of Brunonia.
