Differs from the preceding species in not being caespitose, and 

 in having very rough stems with grooved and strongly-keeled 

 leaves, and only 3 or 4 flowers on each head. I am unable to 

 refer to the original publication of this species ; but it is here 

 described from a specimen in Herb. Mus. Brit., and Borbas gives 

 a good diagnosis of it (Joe. cit.).

Described from C. J. Schlosser's specimens in Herb. Mus. 

 Brit., found near Samobor, in the territorial district of A gram. 

 The plant is certainly distinct from any of the forms of D. Car- 

 thusianorum, and differs from D. pelviformis in the terete stems, 

 shorter leaf-sheath and bracts, and dark red calyx-tube. I), cm- 

 entus differs from it in its caespitose, glaucous habit and in its
