Erythranthe dentata

short-flowered monkey-flower

coastal monkey-flower, tooth-leaved monkey-flower

Habit

Annuals with shallow fibrous roots; stems 4-15 cm, ascending, sharply bent at nodes, branching at nodes near base to mid-stem, covered with minute stalked glands, gland-tipped hairs 0.1-0.3 mm, occasionally with minute sharp-pointed hairs bending backward without glands.

Perennial from well-developed, shallow rhizomes, the stems ascending or loosely erect, 1-4 dm. tall, the herbage with stiff, white hairs.

Leaves

Leaves typically cauline, basal leaves commonly not persisting past flowering;

petiole 1-3 mm;

blade narrowly ovate or elliptic to lanceolate, 5-15 mm long and 2-6 mm broad, mostly even-sized or becoming slightly smaller distally, 3 palmately arranged veins, base becoming narrow, margins entire or finely toothed, apex acute to obtuse, sometimes glandular-hairy as stems.

Leaves opposite, serrate, pinnately veined, but the principle lateral veins arising below the middle;

leaf blades lance-elliptic to ovate, acute, the lower short-petiolate, the upper sessile, 2-7 cm. long and 1-3.5 cm. wide.

Flowers

Axillary flowers 10-20, emerging from nodes at mid- to ends of stems; fruiting pedicels not bent or curved, 5-11 mm, glandular-hairy as stems;

calyx winged, ridged, bell-shaped becoming somewhat ovoid-ellipsoid, strongly inflated, 5-6 mm, margins significantly toothed or lobed, sparsely covered with small rigid hairs, no glands or occasionally slightly sessile-glandular, lobes pronounced, erect;

corollas yellow with red spots or stripes, with bilateral symmetry and weakly bilabiate;

tube-throat cylindric to slenderly funnel-shaped, 3.5-5 mm, not protruding past calyx margin;

limb minutely widened, lobes broadly obovate with rounded apexes;

styles glabrous;

anthers not protruding, glabrous.

Flowers few, solitary in the leaf axils, on long pedicels;

calyx 8-16 mm. long, 5-angled with spreading hairs along the ribs, the 5 teeth acute, 2-5 mm. long;

corolla 2.5-4 cm. long, bilabiate, yellow, the long, strongly-flaring throat often red-dotted, the 5 well-developed lobes sometimes washed with reddish-purple;

stamens 4.
