This form approaches the Scandinavian form-group to which 

 H. constringensNoTrl., H. subalpestre Norrl., and H. prolatatum K. Joh. 

 belong. It resembles most closely the latter in the elothing of its 

 involucres, but is easily distinguished from it by the greater breadth 

 as well as the rounder base of the involucres, by the leafy stem 

 (2 — 'S leaves), and by the regularly, closely, and sharply toothed leaves. 

 As in the case of H. prolatatum it agrees fairly well with H. sagitta- 

 tum Lbg. of Silvatica with reference to its involucres. It must un- 

 questionably be regarded as a western parallel form of H. prolata- 

 tum. Il is doubtless closely allied to the preceding ones, as also 

 to H. ciliolatum, while at the same time it is possible that it stands 

 in a distant, genetic relation to H. holopleurum Dahlst. from Iceland.
