||
Habit | Mat-forming perennial from well-developed, creeping rhizomes, often with stolons as well, the stems 0.5-2 dm. tall, mostly glabrous. | Annual, glandular-hairy to somewhat glabrous (smooth), growing to 0.5-3 dm. in height. The plants are slender, and have either a simple or freely-branching form. Often found growing in uniformly dense patches. The stems frequently appear somewhat reddish. |
Leaves | Leaves opposite, mostly sessile, the blade under 2.5 cm. long, elliptic to ovate, slightly reduced upward, with a few irregular teeth, sub-palmately veined. |
Opposite, slightly to evidently-toothed, 3-5 prominent veins on the upper surface. The blades are 0.5-2.5 cm. long, with a petiole of more or less equal length. |
Flowers | Flowers few, solitary in the leaf axils, on long pedicels; calyx 5-toothed, irregular, the upper tooth much the largest, the 2 lower ones tending to fold upward; corolla large for the size of the plant, 2-4 cm. long, strongly bilabiate, with flaring throat, yellow with maroon dots or splotches on the pubescent lower lip; stamens 4. |
The yellow corollas fuse to form an upper and lower lip (bilabiate), and grow 8-14 mm. long. A conspicuous reddish-brown blotch is found on the lower and sometimes the upper lip. Individual flowers are attached to the stem by a long pedicel. |
Fruit | Capsule. |

Identification notes | The reddish-brown blotch on the lower lip is very diagnostic along with its annual life cycle and tendency to be found in moss mats. The middle lobe of the lower lip tends to be the longest and somewhat curved backwards (deflexed). The lower two teeth of the calyx tend to be more rounded and longer than the upper three calyx teeth. | |
Flowering time | July-September | April-June |
Habitat | Wet meadows and wet, rocky slopes at high elevations in the mountains. | Shady, vernally (springtime) moist places on cliffs and ledges, especially at low elevations; often growing in moss mats. |
Distribution | In the Cascade and Olympic Mountains of Washington; Alaska south to California, east to Montana, Colorado and New Mexico.
|
Occurring on both sides of the Cascades crest in Washington; British Columbia to California.
