Taxonomic Comments

Kartesz (1994) recognized only Mimulus montioides, while the Flora of North America (vol. 17 2019) and Fraga (2012) segregate Erythranthe from Mimulus, and then split several taxa from material formerly identified as montioides: Erythranthe montioides, E. calcicola, E. carsonensis, and E. discolor.

Rank Reasons

Erythranthe discolor is an annual herb that is endemic to California, USA., primarily in the southern High Sierra Nevada and Sierra Nevada foothills. There are over 50 occurrences that have various low to moderate threats. Low elevation occurrences are more greatly impacted by development, with some occurrences likely extirpated due to land use changes.

Range Extent Comments

Erythranthe discolor is endemic to California, USA, where it occurs in the California Floristic Provinces of southern High Sierra Nevada Foothills, southern High Sierra Nevada, and Tehachapi Mountains (Jepson Flora Project 2023).

Threat Impact Comments

Nearly all occurrences are on Federal Land. Despite this, occurrences may still be threatened. Documented threats include off-highway vehicles, road maintenance, competition with invasive and non-native plants, campground use, and fuel reduction activities (K. Ferguson, pers. comm., 2023).

Ecology & Habitat

Habitat

This species grows in meadows and seeps, lower montane coniferous forest, upper montane coniferous forest, pinyon and juniper woodland, cismontane woodland, and Great Basin scrub (K. Ferguson, pers. comm., 2023).
