 perennes ; turiones cum illis permanentes aut foliis dense imbricatis instructi aut laxe 

 foliati, saepe rosulam foliorum gerentes, in caulem fioriferum foliatum aut bracteatum 

 exeuntes, interdum etiam ex axillis, raro solum ex axillis caules floriferos producentes.

 aut saepius folia basalia triloba vel trifida vel triparlita, laciniis vel partitionibus saepe 

 iterum 2 — 3-fidis vel 2 — 3-parlitis, vel etiam lacinulis deuuo lobatis vel fissis, lamina 

 in petiolum sensim angustata aut subito contracta. Caules floriferi raro 1-flori, ple-

Species montanae subalpinae et alpinae, etiam nivales et arcticae fere in tota

 minus in Alpibus numerosae, in Carpathis atque montibus peninsulae balcanicae haud 

 rarae, in Asia centrali atque in Americae boreali-ocndentalis montibus sicut in Andibus 

 Americae meridionalis rarae.
