Leaves basely attached, alternate; petiole 0.5-1(-2.5) cm long, usually ciliate with 2 rows of hairs; blade fleshy to membranous, densely black-glandular (when dried), narrowly ovate or ovate, 1.5-8(-11) x 0.5-3.5(-5) cm, margin ciliate near apex, apex acute to acuminate, base acute to acuminate, sometimes subobtuse, glabrous; venation obvious, pli-or palmately 3-5-veined. Inflorescence terminal, single, or several in upper leaf axils, erect to pendent; peduncle 0.5-1.5 cm long, glabrous, black-glandular; spike to 16 cm long, moderately densely flowered, flowers distinctly separate; floral bracts rounded, glabrous and black-glandular. Fruits laterally attached, globose, reddish brown, apex oblique with subapical stigma.
A black-glandular-dotted, stoloniferous-assurgent herb; stem 1-2 mm. thick, branches ascending to 15 cm. or more, glabrous except for the ciliate petioles and lines decurrent from their margins below the nodes; leaves ovate to ovate-elliptic-lanceolate, 8-13 mm. wide X 15-35 mm. long, or occasionally up to 2.5 X 6 cm., acute to acuminate at both ends or not infrequently blunt or subobtuse, palmately 3-to 5-nerved, or plinerved within the lowermost 5-7 mm., ciliated near the apex, or some leaves throughout, mostly drying dark and subopaque; petiole 5-10 mm. long, grooved above, clasping-decurrent, mostly crisp-ciliate; spikes terminal and from the upper leaf axils, slender, up to 5-8 or occasionally as much as 12 cm. or more long; peduncle 10-15 mm. long; bracts round-peltate, black-dotted; fruit globose-ovoid, apex oblique, somewhat scutelliform and scutellum commonly with a thin margin, stigma subapical.
