specimens he does not know, but thinks they are different from both 

 C. scoparia and C. pratensis. Of these he f^ays : "Mihi ignota; forsan 

 forma C. scoparia ; diftert a C. pratensi, foliis brevioribus magisque 

 scabris, spiels magis approximatis, squamis atrofuscis, &c." — Feb. 16, 

 1888, Joh. Lange. 



From the above it is evident that these forms are included in the 

 specimens referred to C. pratensis, but we must wait for more light 

 before tinall}- deciding.
