I have already proposed* to separate certain species hitherto 

 referred to Hieracium, and characterized by their flat, attenuated 

 achenia surmounted by a dilated epigynous disk, and by their 

 soft capillary pappus disposed in a double series. This group, 

 which I have named Hapalostephium, comprises Hieracium palu- 

 dosum and pyrenaicum of Linnaeus, the Hieracium macrophyllum 

 of Pursh, and the Crepis Sibirica of Linnaeus. M. de La Peyrouse 

 has referred the H. pyrenaicum to his Lepicaune, an unnatural 

 assemblage, which, independent of the faulty name, deserves to 

 be erased from the catalogue of genera. By the removal of 

 these species, and the Hieracium aureum and fruticosum of au- 

 thors, which do not even belong to the same tribe, the genus, 

 although still very extensive, will scarcely admit of further di- 

 vision. The Hieracium pusillum of Pursh from Labrador I have 

 ascertained by an examination of an authentic specimen to 

 belong to the genus Erigeron of authors. The crest of the an- 

 thers in most of the species of this genus is obtuse ; but in the 

 two above described, and in Hieracium murorum, it is acute.
