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