Erythranthe guttata

sessile-leaved monkey-flower

seep monkey-flower, yellow monkey-flower

Habit

Rhizomatous perennials, occasionally rooting at nodes nearest base; stems 20-80 cm, prostrate or decumbent to ascending, only slightly branched, villous eglandular hairs 1-2 mm, occasionally with shorter stipitate-glandular hairs, internodes evident.

A highly variable species, either annual from fibrous roots, or perennial with stolons or rhizomes, the stems from less than a decimeter to nearly a meter high.

Leaves

Leaves cauline, basal ones not persistent, commonly congested; subsessile to sessile;

blade oblong to lanceolate, 30-70 mm long and 10-22 mm broad, pinnate venation, base rounded, margins toothed to finely toothed, apex acute, surfaces hairy as stems.

Leaves opposite, soft and often somewhat succulent, the blades from quite small to nearly 1 dm. long, irregularly dentate, ovate to reniform-cordate;

leaves nearly palmately veined, the 3-7 main veins arising near the base; lower leaves petiolate, becoming sessile upward, those of the inflorescence reduced and clasping.

Flowers

Axillary flowers 4-10, emerging from nodes at mid- to ends of stems; fruiting pedicels generally 22-50 mm, hairy as stems;

calyx winged, cylindric-campanulate, barely inflated, 10-12 mm, villous with gland-tipped hairs, lobes spreading noticeably, strongly unequal, linear-lanceolate to slender-triangular, 5-9 mm, apex long acuminate-apiculate;

corollas yellow, throat faintly marked with blackish-brownish lines, symmetric almost radially or weakly bilaterally, nearly regular or weakly bilabiate;

tube-throat slenderly bell-shaped, 15-18 mm, protruding beyond calyx margin;

lobe apex rounded;

styles glabrous;

anthers not protruding, covered with fine hairs that are stiff to slightly rigid.

Flowers several to many in terminal racemes, on long pedicels, or solitary in dwarf forms;

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

corolla 1-4 cm. long, strongly bilabiate, with flaring throat, yellow with maroon dots or splotches on the pubescent lower lip;

stamens 4.
