Habit | Annuals, fibrous-rooted or filiform-taprooted. | Annuals, slender-taprooted or fibrous-rooted, rarely with runners from basal nodes. |
Stems | erect to ascending, straight or geniculate at nodes, usually simple, (3–)5–15(–24) cm, stipitate-glandular, hairs 0.2–0.5 mm, gland-tipped. |
erect, simple or branched, terete, sometimes 4-angled distally, (5–)30–60(–80) cm, glabrous, glaucous. |
Leaves | cauline, basal not persistent; petiole (5–)8–25 mm; blade palmately 3-veined, deltate or ovate to ovate-lanceolate, 4–12(–17) × 3–10(–14) mm, base rounded to cuneate-truncate, margins usually denticulate, apex acute to obtuse, surfaces stipitate-glandular, hairs 0.2–0.5 mm, gland-tipped. |
basal and cauline; petiole: basal and proximal cauline as long as or much longer than blade, slender, sometimes pubescent or villous, distals absent; blade palmately 3–5-veined, (proximal) ovate to ovate-elliptic or orbicular-ovate, sometimes subcordate, 10–50 mm, midcauline to distal orbicular, 5–45 mm wide, distinctly connate-perfoliate, disclike distally, base rounded to subcordate, margins: proximals denticulate to dentate or coarsely, irregularly toothed, sometimes lobed at base, distals nearly entire or toothed, teeth scattered, small, apex rounded, surfaces glabrous, glaucous. |

Discussion | Erythranthe patula is distinctive with its long-petiolate leaves with ovate blades and its small, weakly bilabiate to nearly radially symmetric corollas. Vestiture may include only minute, stipitate-glandular hairs or it may be an intergrading mix of stipitate-glandular hairs and minute (0.1–0.2 mm), sharp-pointed, eglandular hairs. Plants may have stipitate-glandular pedicels and calyces but hirtellous, eglandular stems, or they may have stipitate-glandular stems and pedicels but hirtellous calyces.

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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
