Tiny little bell shaped flowers 3 on the end of each slender stem. I did notice what the leaves looked like. They were growing at the edge of a bush with scrub oak, Chokecherry and other trees. Welwyn Regional Park, Saskatchewan
I think this flower is Harebell. Found (on the return hike) along the trail to Mineral Spring Waterfall (along the National Hiking Trail in Sheyenne River State Forest).

Neither the Illustrated Flora of BC nor the Flora of N. America keys are really clear for this, so it's a bit hard to separate from C. cusickii, but I went with C. prairea due to the prolonged sheaths and the very short ligules.
Generally, you have a large tufted plant with long stems, very long narrow leaves, "coppery" colouring on the mouth of the sheath, drooping branched heads (refer to FNA descriptions, not the key in Ill. Flora of BC, C. prairea does have a branched inflorescence), spikes androgynous, female scales nearly covering the perigynia, peri with a long beak, veined abaxially but not adaxially, achenes "broadly trullate-ovate", etc.
There's just one field photo, it shows habitat and also some of the plants if you zoom to the lower centre part of the photo you can see the arching drooping stems and heads.
For submission to UBC.
