Trientalis borealis

Starflower

Duck Mountain Provincial Park
22-June-2002

Note that Flora of Alberta, in its description of family Primulaceae, states that the corolla is gamopetalous (petals united).  However, it keys this family as having either united or separate petals.  Budd's Flora keys the family as having united petals.  In these pictures, the union of the petals is hard to see.
