numcrous hairs on leaf and stem, its broader and larger radical 

 leaves, with sharp and often long and subulate teeth and its l)roader 

 and shorter stem-leaves and longer involucres, more densely covered 

 with glandular hairs without admixtnre of simple hairs. From the 

 one mentioned below it is distingnished by its broader, and more 

 finely toothed radical leaves, with longer petioles, its fewer and 

 smaller stem-leaves and its longer involucres, with narrower and more 

 obtuse phyllaries, densely glandular, and showing a few stellate hairs 

 at the margins. The present species is not closely related to H. glau- 

 cicolor in spite of its outward resemblance.
