Erythranthe ptilota

short-flowered monkey-flower

sessile-leaved monkey-flower

Habit

Annuals with shallow fibrous roots; stems 4-15 cm, ascending, sharply bent at nodes, branching at nodes near base to mid-stem, covered with minute stalked glands, gland-tipped hairs 0.1-0.3 mm, occasionally with minute sharp-pointed hairs bending backward without glands.

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.

Leaves

Leaves typically cauline, basal leaves commonly not persisting past flowering;

petiole 1-3 mm;

blade narrowly ovate or elliptic to lanceolate, 5-15 mm long and 2-6 mm broad, mostly even-sized or becoming slightly smaller distally, 3 palmately arranged veins, base becoming narrow, margins entire or finely toothed, apex acute to obtuse, sometimes glandular-hairy as stems.

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.

Flowers

Axillary flowers 10-20, emerging from nodes at mid- to ends of stems; fruiting pedicels not bent or curved, 5-11 mm, glandular-hairy as stems;

calyx winged, ridged, bell-shaped becoming somewhat ovoid-ellipsoid, strongly inflated, 5-6 mm, margins significantly toothed or lobed, sparsely covered with small rigid hairs, no glands or occasionally slightly sessile-glandular, lobes pronounced, erect;

corollas yellow with red spots or stripes, with bilateral symmetry and weakly bilabiate;

tube-throat cylindric to slenderly funnel-shaped, 3.5-5 mm, not protruding past calyx margin;

limb minutely widened, lobes broadly obovate with rounded apexes;

styles glabrous;

anthers not protruding, glabrous.

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.
