a note added, " sed petalis dentatis." It certainly does not agree 

 with the description of this species, but differs from it in many 

 points. I have failed to match it with any other Algerian species, 

 though it does seem to be very similar to D. fragrans of the 

 Caucasus. The characters of the plant are not emphasized 

 sufficiently so as to make it appear to be specifically distinct from 

 others of the same group with which it is evidently allied ; and 

 I therefore prefer to consider it as a variety. The name is derived 

 from the length of the leaf-sheath as compared with that in the 

 specific type.
