T. ceratophorum (Ledeb.) DC. , Prodr. 7: 146 (1838). Although this name has always been used for this group of plants in the aggregate sense, it has never been typified and it is uncertain to which of the segregates the name applies.

13 species have been described for Europe, mainly from the Alps and N.W. Europe. The following are the 2 which are most widespread:
