Erythranthe nasuta

primrose monkey-flower

large-nose monkey-flower, snouted monkey-flower

Habit

Mat-forming perennial from long, thin rhizomes, the stem lax, up to 6 cm. long.

Annuals with fibrous roots or a slender taproot; stems usually 2-35 cm, erect to ascending-erect or decumbent, unbranched or branched from nodes nearest base, 4-angled or occasionally weakly 4-winged, thin and wiry or hollow, glabrous except for small villous-glandular areas directly above nodes, occasionally with minute rigid hairs distally.

Leaves

Leaves opposite, crowded near the ground, short-hairy abaxially (underside), viscid to glabrous adaxially (upperside);

leaves oblanceolate, sessile, nearly entire, 3-nerved from the base, 7-25 mm. long and 3-11 mm. wide.

Leaves basal and cauline or basal may not persist;

petioles 3-35 mm from base to mid-stem with narrowly flanged bases, becoming sessile distally;

blade reddish or purple-spotted beneath, somewhat ovate to nearly orbicular, approximately 10-49 mm long and 10-25 mm broad, leaves nearest base largest and persistent, palmate venation with 3-5 veins, base cuneate to truncate or nearly cordate, margins irregularly toothed or nearly lacerate, commonly doubly-toothed, 4-9 main teeth per side, sometimes sublacerate to sublyrate near base, apex acute to obtuse, surfaces glabrous or hirtellous with hairs that are dull, cylindrical, sharp-pointed, eglandular.

Flowers

Flowers solitary on slender pedicels up to 10 cm. long arising from the leaf clusters;

calyx narrow, 4-8 mm. long, mostly glabrous, the 5 teeth short, equal;

corolla yellow, often dotted with maroon, 1-2 cm. long, scarcely bilabiate, the 5 lobes spreading, shallowly notched, the throat somewhat flaring;

stamens 4.

Axillary flowers typically 2-12, emerging from nodes at mid- to ends of stems; fruiting pedicels usually 7-20 mm, longer than subtending leaves, becoming glabrous, occasionally glandular-villous on upper surface at axils;

calyx nodding at 30-180 degrees, commonly purplish or purple-spotted, ovoid-campanulate, inflated, compressed across sagittal plane, usually 10-15 mm, hirtellous or appressed-hirtellous, or glabrous, slightly short-ciliate at sinuses, throat closing, upper lobe generally longer than lower lobe, slightly sickle shaped;

corollas yellow, throat commonly with red spots, lower limb usually with a red splotch at base, symmetric bilaterally, weakly bilabiate;

tube-throat widely cylindric, 8-12 mm, equal to or protruding 1-2 mm beyond calyx margin, limb expanded 6-12 mm;

styles slightly rough or glabrous;

anthers not protruding, glabrous.

Fruit(s)

Capsule.

Capsules 5-9 mm, included.
