Habit | Perennials, rhizomatous, sometimes rooting at proximal nodes. | Annuals, fibrous-rooted or slender-taprooted, rarely rooting at nodes. |
Stems | erect, sometimes decumbent basally, branched, often fistulose, (25–)50–120(–160) cm, densely hirsutulous to softly hirtellous-puberulent to pilose-hirsutulous, hairs usually crinkly, and eglandular or with a mixture of hirtellous-puberulent and stipitate-glandular hairs, sometimes ± stipitate-glandular or glandular-villous without hirtellous-puberulent hairs. |
erect, rarely prostrate to prostrate-ascending, few-branched, 3–17 cm, moderately villous-glandular, hairs gland-tipped, or mixed hirtellous and stipitate-glandular. |
Leaves | basal and cauline, basal usually not persistent, bracteate in inflorescence; petiole 10–80 mm, gradually reduced distally; blade subpinnately, sometimes palmately, 5–7-veined, ovate to broadly elliptic, 25–60 × 20–40(–60) mm, usually 1–2 times longer than wide, base truncate or truncate-cuneate to subcordate, margins crenulate to dentate, proximally sometimes sublyrate, apex rounded to obtuse, surfaces of distals densely hirsutulous to softly hirtellous-puberulent to pilose-hirsutulous, hairs usually crinkly, and eglandular or with a mixture of hirtellous-puberulent and stipitate-glandular hairs, sometimes ± stipitate-glandular or glandular-villous without hirtellous-puberulent hairs. |

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.

F. W. Pennell (1947, 1951) considered Erythranthe arenicola an endemic of Monterey County, but plants from adjacent San Luis Obispo and Santa Cruz counties also belong here. Most of the localities are at seaside, but some are more than a mile inland. Erythranthe arenicola is hypothesized here to be a derivative of E. guttata or E. grandis, retaining the herkogamous breeding system of its putative ancestor but reduced in size and duration.
