	Erythranthe linearifolia	Erythranthe androsacea
Phenology	Flowering Jul–Sep.	Flowering Feb–May.
Habitat	Wet banks, Darlingtonia seeps and bogs, seepages in serpentine talus.	Moist open areas on gentle slopes.

Discussion	Erythranthe linearifolia is endemic to serpentine substrates in Shasta, Siskiyou, and Trinity counties; typical E. primuloides occurs in the same area but not on serpentine. Erythranthe linearifolia is distinct from E. primuloides especially in its narrow leaves and cespitose habit. A collection from Tulare County appears to be E. linearifolia (Shevock 10597, CAS), but this appears to be far out of range and the voucher should be reexamined; it probably is better identified as an unusual collection of E. primuloides.

Erythranthe androsacea occurs primarily in the southern half of California but is scattered as far north as Lake and Modoc counties.
