 but in too few specimens for distribution. The species should rank next to E, modestum ; but 

 its heads are nearly twice as large; the rays (3 lines long) purple^ more imbricated; the involucre 

 scarcely hispid, and the pappus less fragile ; the exterior series longer. It is one of the species 

 intermediate between Erigeron (Pseuderigeron) and Diplopappus.

 which is somewhat peculiar.

 with the pappus more copious and finer than usual.
