Bur Buttercup, Ranunculus testiculatus, New to Eastern Canada

Michael J. Oldham, Clive E. Goodwin, Sean Blaney


Bur Buttercup (Ranunculus testiculatus) is newly reported for eastern Canada based on two collections from campgrounds in southern Ontario. This vernal, annual, Eurasian weed is widespread in western North America and is expanding its range in the east; it should be expected elsewhere in eastern Canada. Bur Buttercup is known to be toxic to livestock.
