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 Linnæus, the Hieracium macrophyllum 
of Pursh, and the Crepis Sibirica of Linnæus. M. de La Peyrouse 
has referred the H. pyrenaicum to his Lepicaune, an unnatural 
assemblage, whic 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 ihe.
