Erythranthe breweri

sharp-leaved monkey-flower, showy monkey-flower

Brewer's monkey-flower

Rhizomatous perennials, occasionally producing many long runners from nodes near base; stems 20-100 cm, erect, not branched, ends of stems densely pubescent with minute and somewhat rigid hairs.

Slender annual, the stem simple or sparingly branched, up to 15 cm. tall, purplish tinged and covered with stalked glands.

Leaves

Leaves mostly cauline, basal leaves generally not persistent;

petioles 8-25 mm near base, 3-5 mm mid-stem, sessile distally;

blade ovate-triangular to ovate-lanceolate, typically 20-50 mm long and 10-30 mm broad, palmate venation with 5-7 veins, base rounded to truncate to shallowly cuneate, margins sharply toothed, apex acute, surfaces occasionally becoming glabrous, distalmost surfaces hairy as stems.

Leaves opposite, linear to linear-oblanceolate, 1-2 cm. long and 1-4 mm. wide.

Flowers

Axillary flowers generally 2-7, emerging from nodes at ends of stems; fruiting pedicels 18-35 mm, distalmost pedicels hairy as stems with hairs often barely deflexed;

calyx green with occasional red spots, ovoid, inflated, compressed across sagittal plane, 15-19 mm, hairy as stems, throat closing, lobe margins villous;

corollas yellow, throat commonly red-spotted, symmetric bilaterally, bilabiate;

tube-throat widely funnel-shaped, 18-26 mm, protruding 10-15 mm beyond calyx margin;

limb expanded 22-30 mm;

styles prominently hirsute to villous;

anthers not protruding, glabrous.
