The oppositely arranged oval leaves may be several centimeters long and some are borne on short petioles. The yellow flower may be over 4 centimeters long, its narrow tubular throat opening into a wide, two-lipped mouth. The base of the flower tube is encapsulated in a calyx of sepals with uneven lobes.

Erythranthe tilingii is often nearly impossible to distinguish from its common relative, Erythranthe guttata, as their characteristics can intergrade; one of the most notable differences is the arrangement of the flowers, which are axial in E. tilingii but in a raceme in E. guttata.Jepson eFlora treatment for Erythranthe tilingiiSouthwest Colorado WildflowersJepson Manual dichotomous key for Mimulus By 2014 three species that were formerly part of E. tilingii had been made their own separate species: Erythranthe caespitosa, Erythranthe corallina, Erythranthe minor.

Distribution It is native to much of western North America, from Alberta to California to New Mexico to Montana. It grows in moist and wet habitats, such as streambanks and mountain meadows, and is generally found at high elevation.
