fe. Arizonicus var. subafinis GREENE, |. c.60. Not Gray. 
Lf. namenus GREENE, Pitt. 3: 91. 1896. 
Differs from the type in its stouter habit, radical leaves often 
cordate at base, fisually not much lobed, but variable: flowers 
larger: akenes either hairy or glabrous. New Mexico and 
Arizona to Montana, east to Labrador. 
Var. pinetorum (GREENE). 
Le. cardiophyllus var. pinetorum GREENE, Pitt. 4: 144. 
1900. 
Stem short, canescently villous: roots strongly and copiously 
developed: leaves oval, often subcordate, or truncate at base, 
margins crenate: flower I inch across: head of akenes not so 
long{as in the type, ovoid or globose. Pine woods, Graham’s

43. R. vicinalis GREENE, Pitt. 4: 145. 1g00. 
This is an Alaskan plant from the region of Fort Selkirk, 
which differs from /?. pedatifdus in its larger flowers, and in 
having the radical leaves cleft or parted into about 7 lobes, and 
these again 3-cleft. But we find this leaf character in some 
Colorado forms of that type.
