Alaska to Ore. G.F. 10:215. B.M. 8353. - C. campanulatua, Greene. According to Greene, this species differs from the preceding chiefly in the petals being united at the base and the anthers opening with a pore at the apex, and occurs in Wash., while C. pyrolaeflorus is restricted to Alaska, but the specimens from Ore. and Wash, do not differ from C. pryolaeflorus; possibly C. campanulatus was based only on an abnormal form.
