Low herbs with palmately lobed or compound leaves, adnate

A. arvensis Scop. Fl. Cam. ed. 2, i, 115. Annual ; somewhat strigose-

 broad, deeply 3-lobed, segments 2-4 cleft; stipules large, 2-5 cleft; flowers 

 fascicled in the axils of the leaves, % of a line long, on slender pedicels 

 or nearly sessile : bractlets very small : stamens 1-2 : achene solitary, com- 

 pressed. Common in meadows and open places, Vancouver Island to 

 California: Europe. 



Tribe 3. Dryadese Vent. Tabl Hi, 349. Calyx campanulate or
