is an uncommon species, endemic to the Colorado Plateau (though not New Mexico), found around seeps and springs in canyons, often growing on vertical rock faces.
Flowers may be upright or nodding, and are formed of five spurred sepals and five forwards-projecting petals. The petals are white to pale yellow while the sepals may be pink, pale purple or pale blue. Spurs are between 0.6 and 1.2 inches in length, and are usually parallel, though can be somewhat spreading, or touching, angled inwards. A group of different-length stamens projects forwards; they have white or pale yellow filaments and yellow/orange anthers.
