Erythranthe glaucescens

Erythranthe calcicola
Phenology Flowering Mar–May(–Jun). Flowering Apr–Jun.
Habitat Seepage areas, wet rocks, moist cliffs, pool edges, gravelly stream banks, serpentine outcrops, roadsides and roadcuts, low pastures, riparian woodlands, blue oak woodlands, chaparral, grasslands. Creosote bush and Joshua tree woodlands, usually on carbonate substrate, primarily on talus slopes.
Elevation 80–900(–1100) m. (300–3000(–3600) ft.) 900–2200 m. (3000–7200 ft.)

Discussion

Plants from one locality in Butte County are unusual in producing filiform, small-leaved runners from basal cauline nodes. Erythranthe glaucescens is known only from Butte and Tehama counties.

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.
