Erythranthe breviflora

great purple monkey-flower

short-flowered monkey-flower

Habit

Perennial from stout, branching rhizomes, the stout stems clustered, 3-10 dm. tall; herbage viscid-villous.

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.

Leaves

Leaves opposite, sessile, with several prominent veins from the base, irregularly dentate to entire, the lower ones reduced;

leaves lanceolate to ovate or elliptic, acute, 3-7 cm. long and 1-3.5 cm. wide.

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.

Flowers

Flowers solitary in the leaf axils on pedicels 3-6 cm. long;

calyx 1.5-2.5 cm. long, the 5 teeth sharp-pointed and equal;

corolla showy, purplish-pink, marked with yellow, 3.5-5 cm. long, strongly bilabiate;
