The three images below are placed here with uncertainty.  The multiple stems and number of basal leaves together with the relatively low tube:limb ratio of the corolla is suggestive of M. oblongifolia.  However, the images may simply represent an extreme form of M. longiflora

The first image below includes stems from two rather different plants from Washington that were found growing next to each other.  The plant with mostly pink flowers and narrower upper leaves (see also 2nd and 3rd image below) is a very good match to M. umbratilis as discussed in VPPNW (Hitchcock et al.) and as currently recognized in the checklist of Washington plants.  The discussion in VPPNW indicates that some forms of M. umbratilis (like the blue flowered stem with broader leaves in the first image would likely key to M. ciliata.  Indeed, the leaves of this plant are very similar to those of M. ciliata and the corolla tube:limb ratios match closely, the values being somewhat lower than those of the pink flowered form of M. umbratilis.  The Oregon flora checklist places M. umbratilis in synonymy with M. oblongifolia. The Oregon specimens treated as M. oblongifolia at OSC include a few that were previously identified as M. umbratilis but none that are particularly good matches to either of the two extreme forms represented by the plants in the first image below.  Rather, the foliage of specimens treated as M. oblongifolia at OSC tends to be similar to the pink flowered form of M. umbratilis in the first image while the flowers are more similar to those of the blue-flowered form.  Thus, it may be the case that M. umbratilis has simply been misapplied in reference to Oregon plants.
