The above bibliography shows elearly how the species finally (Packard) 

 got its scientific name, and it became recognized, that all the other species of 

 the same genus in the Arctic are only synonyms of B. paludosa. Only the most 

 important works published since the seventies are given above. The specimens 

 follow :
