 very leafy, villous at base, pubemlent above ; leaves ovate-lanceolate, pinnatifid, 

 and the lobes cut and toothed ; pedicels glandular, about equaling the mostly 

 serrate slightly glandular or glabrate calyx-lobes. {Dasystoma Benth.) — Dry

Var. ambigens Fernald. Stems glandular-villous above ; pedicels and calyx
