Capsules	included, 8–12 mm.
Anthers	included, glabrous.

	Erythranthe grandis
Phenology	Flowering (Apr–)May–Jul(–Sep).
Habitat	Beaches, dunes, coastal bluffs, wet cliff faces, mud flats and seeps, marshes, drainage ditches, creeks, rarely in coastal sage scrub.
Elevation	0–200(–800) m. (0–700(–2600) ft.)
Distribution	CA; OR [WildflowerSearch map]
Discussion	The densely, evenly puberulent vestiture of pedicels, calyces, and distal stems usually is diagnostic, especially in combination with the large flowers (corollas and mature calyces) and tall stature. Plants from scattered collections are much shorter than normal but have large corollas and characteristic vestiture. Erythranthe grandis characteristically occurs in coastal localities from southern California to northern Oregon but also is found in inland localities and habitats near the coast but well away from salt spray.
