Flowers: about 1 to 3 at the ends of the stems, stalkless or short-stalked. Calyx hairless or sometimes cobwebby-short-hairy, slightly shorter than the corolla tube, the 5 lobes sharp-pointed, rather narrow and often thickened, but not very firm, the membranes between the 5 ridges of the calyx flat. Corolla white or occasionally bluish, the tube 10-14 mm long, the 5 broad, rounded lobes 6-11 mm long. Style 5.5-8 mm long. May-August.

Fruits: capsules, elliptic, splitting along 3 lines, containing few seeds.


Open or wooded, often rocky places, from the higher foothills to above timberline in the mountains, in w. and s.c. parts of MT. Also from adjacent ID to CO and n.e. UT, and in Elko Co., NV.
