Musk-flowered monkey flower is a perennial with lax or prostrate stems from 5-70 cm long long. It is often freely branched and the herbage is often sticky-hairy with numerous slender, flattened, shining white hairs as seen above. The herbage tends to be slimy and sometimes strongly musk-scented. The stems are simple and pinnately veined with either short petioles or sessile. The leaf blades are ovate to elliptic-ovate or lance-ovate in shape. The blades range from 1-8 cm long and 7-35 mm wide.
The flowers have long stems. The calyx is 7-13 mm long with pointed lobes or teeth 2-4 mm long. The upper tooth or lobe of the calyx is slightly longer than the others. The calyx is glandular-hairy, especially on the 5 ribs. The corolla is 1.5-3 cm long, thin in cross-section, and yellow with some occasional dark lines or dots. The 5 lobes are barely two-lipped as the lobes spread widely.
Musk-flowered monkey flower is found in moist meadows from near sea level to medium elevations in the the mountains.
Musk-flowered monkey flower may be found from southern British Columbia south to California, and east to Montana, Utah, and Colorado.
