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

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

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, the pedicels usually longer than the calyx;
