Erythranthe washingtonensis

short-flowered monkey-flower

Washington 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. Annuals with fibrous roots or threadlike taproot; stems 5-25 cm, erect to ascending, straight or sharply bent at nodes, typically heavily branched, not angled; puberulent- to villous-glandular, flattened gland-tipped hairs 0.1-0.8 mm, sometimes transparent.
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 cauline, basal ones not persistent;

petioles 2-14 mm;

blade triangular to ovate to narrowly ovate, 4-16 mm long and 2-11 mm broad, palmate venation, base rounded to cuneate to truncate, margins finely toothed or entire, apex acute, surfaces hairy-glandular as stems.
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;

anthers not protruding, glabrous.

Axillary flowers 1-6, emerging from nodes throughout; fruiting pedicels 20-50 mm, densely covered with minute stalked glands;

calyx greenish, ridged, tubular, slightly inflated, 6-8 mm, margins toothed or lobed, covered with minute stalked glands, lobes pronounced, erect;

corollas yellow with small reddish brown dots, lower limb with two whitish patches, symmetric bilaterally, bilabiate;

tube-throat funnel-shaped and 8-10 mm, protruding beyond calyx margin;

limb expanded 7-10 mm, lobes obovate-oblong, apex rounded to somewhat cuneate;
