Discussion | Erythranthe calcicola was previously included in the broader concept of E. montioides; the former can be distinguished by its glandular herbage, broader lanceolate to ovate leaves, strongly angled calyces, and smaller flowers. The species is restricted to the northern Mojave Desert and southwestern Great Basin and occurs primarily on talus slopes on substrates derived from carbonate rock.
