constituting a distinct genus, to which, it is very probable, the 
Hypocheris sonchoides of M. Kunth should also be referred. 
From Hypocheris, which must now be limited to H. glabra and 
minima, it will be necessary to separate H.radicata and maculata, 
essentially distinguished by having the pappus uniformly stipi- 
tate. This division, first proposed by Scopoli under the name 
of Achyrophorus, has been very properly adopted by Geertner. 
The genus Seriola of Linnzus, the Achyrophorus of Vaillant, 
which also belongs to this family, is characterized by a simple 
polyphyllous involucrum, and by the rays of the pappus being 
dilated towards the base.
