Habit | Mat-forming perennial from well-developed, creeping rhizomes, often with stolons as well, the stems 0.5-2 dm. tall, mostly glabrous. | Rhizomatous perennials, rooting at nodes nearest the base, occasionally producing runners with creeping form and small leaves, forming colonies of mats, rhizomes threadlike; stems 3-10 cm, usually prostrate or with some curving upward distally, usually massed, round or somewhat flat, branching, may be glabrous or slightly hirtellous or with stalked glands. |
Leaves | Leaves opposite, mostly sessile, the blade under 2.5 cm. long, elliptic to ovate, slightly reduced upward, with a few irregular teeth, sub-palmately veined. |
Leaves both basal and cauline; petiolate, proximal petioles 2-5 mm, becoming sessile distally; blade commonly purplish beneath, orbicular to ovate to narrowly elliptic, leaves nearest base somewhat lyrate, 3-12 mm and becoming larger farther from base, palmate venation with 3 veins, base wedge-shaped, margins entire to barely finely toothed, apex obtuse, somewhat puberulent above and beneath, hairs minute and stipitate-glandular. |
Flowers | Flowers few, solitary in the leaf axils, on long pedicels; calyx 5-toothed, irregular, the upper tooth much the largest, the 2 lower ones tending to fold upward; corolla large for the size of the plant, 2-4 cm. long, strongly bilabiate, with flaring throat, yellow with maroon dots or splotches on the pubescent lower lip; stamens 4. |
Axillary flowers 1-3, from nodes farthest from base, usually solitary; fruiting pedicels generally 10-30 mm, somewhat villous with short gland-tipped hairs, occasionally hirtellous; calyx broadly bell-shaped, inflated, compressed along sagittal plane, 7-15 mm, glabrous or hirtellous or stipitate-glandular, throat closing, lobe pair nearest base curving upwards, other lobes 3-5 mm, prominently protruding; corollas yellow with dark red spots, symmetric bilaterally, bilabiate; tube-throat widely funnel-shaped to nearly cylindric, 15-18 mm, protruding beyond calyx margin; lower limb deflexed and spreading, upper limb curving upward, palate partially closed; styles slightly hirtellous; anthers not protruding, glabrous. |
