Radical leaves pinnate, upper nearly simple, all with 

 adnate stipules; flowers yellow; calyx 5-lobed, with 5 

 outer sepals ; petals 5 ; carpels numerous, each ending, in 

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



G. urbanum, L., Wood-Avens, with small yellow flowers, 

 is very common in woods and hedges. G. rivale, L., 

 with larger flowers, and calyx large, red-brown, is fre- 

 quent in wet places. The following are alpine: G. 

 pyrenaicum, L. ; petals considerably longer than calyx, 

 carpels small, terminal lobe of leaf orbicular-reniform ; 

 Pyrenees. G. montanum, L. (Sieversia montana, Spr.) ; 

 stem without runners, flower solitary, leaf -segments 

 unequally crenate, terminal segment very large; high 

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

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

 runners, leaf-segments sharply dentate, terminal segment 

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

 medium, Ehrb., and inclinatum, Schleich., are probably 

 hybrids.

Resembling Geum, but fruit not awned ; flowers 

 purplish-brown. Not alpine. 



C. palustre, L. ; petals dark purple, smaller than the 

 purplish sepals ; wet places ; Switzerland, Pyrenees, 

 local.
