natural Family of Plants called Compositce. 129 



Since the publication of Willdenow's Species Plantarum very 

 few alterations have been made in the genus Galea. 



In Persoon's Synopsis two of the species are excluded ; namely, 

 Galea scoparia, which, following Swartz, he has referred to Bac- 

 charts: and Galea aspcra, adopted from Richard as a species of 

 Melananthera. The additional species in the work referred to are 

 C. cordifolia of Swartz, already noticed as a genuine Galea ; C. acu- 

 leata and spectahilis oi Labillardiere, which belong to Gassinia ; 

 and C. cordata, adopted from Loureiro, of whose plant nothing is 

 known except from the short description in Flora Cochinchinenlis, 

 which is only sufficient to render it probable that 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 Galea retained 

 all the species of this genus given by Persoon ; and also Galea 

 aspera ; which, however, he has in a subsequent 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 referable 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 

 Urunonia. 



I have named the Brazil plant 



AciCARPHA SPATHULATA. 



Herba annua ? glaberrima, ramosa, diffusa. Rami adscendentes, 

 angulati. Folia sparsa, petiolata, exstipulata, spathulata mu- 

 cronulo brevissimo, sesquiuncialia, crassiuscula ? glauca? sce- 

 piils integerrima ; inferiora quandoque extra medium dentata
