Erythranthe suksdorfii

sessile-leaved monkey-flower

miniature 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.

Slender annual, often much branched, the stem 3-10 cm. tall; herbage finely glandular-puberulent.

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, small and rather numerous, linear to narrowly oblong, mostly sessile and entire, 1- to 3-nerved from the base, up to 2 cm. long.

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 solitary in the leaf axils on pedicels under 1 cm. long, spreading and up-turned at the tip;

calyx glandular-puberulent, 3-5 mm. long, the 5 short teeth rounded;

corolla yellow, faintly spotted, 4-8 mm. long, only slightly bilabiate, the 5 lobes equal, notched at the tip, the throat narrow, under 2 mm. wide;

style longer than the calyx;

stamens 4.

Fruit(s)

Capsules 6-8 mm, included.
