STUDIES IN THE COMPOSIT.^. 2i 



represents the genus now under consideration, and was pub- 

 lished in 1833/ that is, two years prior to CalUchroa. 



Arnott, perceiving that Hooker's two species of Blephari- 

 pappifs were really of two genera, separated them, proposing 

 a new name, Eriopappits, but awkwardly, and indeed inad- 

 missably, took Hooker's first species, or typical BLEniARi- 

 PAPPUS, for the type of Eriopappns. This was done in the 

 second edition of Lindley's Introduction (1836). Kultall, in 

 18^1, corrected all this; but of course, Asa Gray when his 

 day came, stood by the error of Arnott, ignoring Nuttall's cor- 

 rection of it, and so we have Blepharipappns applied, in the 

 Synoptical Flora, to a genus the lawful name of which is 

 Ptilonella. 



I subjoin an attempt to give the correct nomenclature of 

 all the species known.
