This plant was photographed near Mt. Renshaw (north of McBride BC) in the western Rockies in August 2015. I've tentatively ID'd it as Epilobium hornemannii, but in all the photos I've seen of that species even the newly open flowers look quite cruciform, with non-overlapping petals at 90 degree angles, while the flowers on my plant were almost all saucer shaped with broad overlapping petals. Only one very mature flower had a somewhat cruciform shape. Is this E. hornemannii or another species?
