 fruit, in a persistent stiff style, often hooked at the tip.

 unequally crenate, terminal segment very large; high 

 pastures ; Alps, Jura, Pyrenees. G. reptans, L. {Siever- 

 sia reptans, Spr.); flower large, solitary, stem with long 

 runners, leaf-segments sharply dentate, terminal segment 

 3-5-cleft; high; Alps, Dauphiny, Pyrenees. G. inter- 

 mediuniy Ehrb., and inclinatum^ Schleich., are probably 

 hybrids.

 purplish sepals ; wet places ; Switzerland, Pyrenees,
