Ranunculus fascicularis A. A. Reznicek

Sandy oak savanna, dry grassy openings and and prairies; shallow soil over limestone pavement especially on Drummond Island; rock outcrops, ledges and "balds." Widespread but quite local in southern Michigan; rare on rock outcrops in the Upper Peninsula. 

This is a very early-flowering and showy species, usually readily distinguished from small plants of R. hispidus by the less sharply toothed leaves and the short tuberous-swollen roots.
