Habit | Rhizomatous perennials, occasionally producing many long runners from nodes near base; stems 20-100 cm, erect, not branched, ends of stems densely pubescent with minute and somewhat rigid hairs. | A highly variable species, either annual from fibrous roots, or perennial with stolons or rhizomes, the stems from less than a decimeter to nearly a meter high. |
Leaves | Leaves mostly cauline, basal leaves generally not persistent; petioles 8-25 mm near base, 3-5 mm mid-stem, sessile distally; blade ovate-triangular to ovate-lanceolate, typically 20-50 mm long and 10-30 mm broad, palmate venation with 5-7 veins, base rounded to truncate to shallowly cuneate, margins sharply toothed, apex acute, surfaces occasionally becoming glabrous, distalmost surfaces hairy as stems. |
Leaves opposite, soft and often somewhat succulent, the blades from quite small to nearly 1 dm. long, irregularly dentate, ovate to reniform-cordate; leaves nearly palmately veined, the 3-7 main veins arising near the base; lower leaves petiolate, becoming sessile upward, those of the inflorescence reduced and clasping. |
Flowers | Axillary flowers generally 2-7, emerging from nodes at ends of stems; fruiting pedicels 18-35 mm, distalmost pedicels hairy as stems with hairs often barely deflexed; calyx green with occasional red spots, ovoid, inflated, compressed across sagittal plane, 15-19 mm, hairy as stems, throat closing, lobe margins villous; corollas yellow, throat commonly red-spotted, symmetric bilaterally, bilabiate; tube-throat widely funnel-shaped, 18-26 mm, protruding 10-15 mm beyond calyx margin; limb expanded 22-30 mm; styles prominently hirsute to villous; anthers not protruding, glabrous. |
Flowers several to many in terminal racemes, on long pedicels, or solitary in dwarf forms; calyx 5-toothed, irregular, the upper tooth much the largest, the 2 lower ones tending to fold upward; corolla 1-4 cm. long, strongly bilabiate, with flaring throat, yellow with maroon dots or splotches on the pubescent lower lip; stamens 4. |
