38. — R.\NUNCULUS FA8CICULA1ÎIS, Mithlenlierg: 



Root composed of a fascicle of thick fle.shy fibres, or slender fusiform tubers. Stem 

 short. Leaves ternately divided in a pinuatifid manner, more or less comi)ound, jjubescent 

 wth appressed silky hairs. Petals twice as long as the sepals. Carpels very short, 

 usually margined, with slender terminal beaks. Some of my specimens are precisely like 

 Hooker's figure in Fl. B.-A., biit the plant varies with inuch broader and more irregular 

 leaf-lobes.

This species is indicated by Sir William Hooker (Fl. Bor.-Am.) as ranging from 

 "Canada" (which included, at the time he wrote, the provinces of Lower Canada or 

 Quebec and Upper Canada or Ontario) to the south end of Lake Wiunijieg. But the 

 results of subsequent observation tend to limit this range ; the plant has been observed, 

 so far, only in the districts lying on the north and west shores of Lake Ontario, not 

 extending either into Quebec eastwardly nor westwardly into Manitoba and the North- 

 West Territory.
