sharp-leaved monkey-flower, showy monkey-flower

Habit

Mat-forming perennial from well-developed, creeping rhizomes, often with stolons as well, the stems 0.5-2 dm. tall, mostly glabrous.

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.

Leaves

Leaves opposite, mostly sessile, the blade under 2.5 cm. long, elliptic to ovate, slightly reduced upward, with a few irregular teeth, sub-palmately veined.

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.

Flowers

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

calyx 5-toothed, irregular, the upper tooth much the largest, the 2 lower ones tending to fold upward;

corolla large for the size of the plant, 2-4 cm. long, strongly bilabiate, with flaring throat, yellow with maroon dots or splotches on the pubescent lower lip;

stamens 4.

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;
