Characteristics

Herbs, perennial, often ± woody at base; taproot long and ropelike, woody. Stems prostrate to decumbent, usually profusely branched throughout, 3-15 dm, minutely pubescent, often glandular, sometimes spreading villous or hirsute in basal portions, minutely pubescent, sometimes glandular, glabrate, or glabrous distally. Leaves usually distributed throughout plant and into much of inflorescence; larger leaves with petiole 5-25 mm, blade broadly lanceolate, ovate, or broadly ovate, occasionally ± round, 20-70 × 10-60 mm (distal leaves smaller, often proportionally narrower), base truncate, broadly cuneate, or round, rarely cordate, margins sinuate, apex acute to obtuse or round, adaxial surface glabrous or sometimes sparsely puberulent, rarely densely glandular-pubescent, abaxial surface paler than adaxial surface, glabrous or sometimes sparsely puberulent, rarely densely glandular-pubescent, often with large multicellular hairs along veins, neither surface punctate. Inflorescences axillary or terminal, forked unequally ca. 3-6 times, open, without sticky internodal bands; branches divergent, terminating in compact subumbellate or capitate 5-flowered clusters. Flowers: pedicel shorter than 0.5 mm; bract at base of perianth usually quickly deciduous, 1, linear-lanceolate to ovate, 0.5-1 mm; perianth maroon, or magenta (or rarely white or yellow) [pink], campanulate beyond constriction, 1-3.5 mm; stamens 2-3, slightly exserted. Fruits (2-)5-20(-30) per cluster, gray-brown to brown, narrowly obovate and tapering at both ends or clavate, 2.6-4 × 0.9-1.2 mm (l/w: 2.7-3.5), apex rounded to rounded-conic, moderately densely to densely stipitate-glandular on ribs and in sulci; ribs 5, rounded, smooth; sulci 1-2.5 times as wide as base of ribs, not rugose, not papillate. 2n = 52.

Inflorescences mostly terminal and subterminal, upper leaves reduced to form ascending panicle, 2-8-flowered clusters. Pedicel to 1 mm. Perianth limb white, pink, or mauve, rarely purplish red, to 2(-2.5) mm. Stamens (1-)3(-4), 1.5-4.5 mm. Anthocarp fusiform, 3-3.5(-4) mm, obviously 5-ribbed, usually glandular hairy.

A herb. It can lie along the ground and be spreading. It can grow for one year or keep growing from year to year. It grows 0.1-1 m high. It can spread 2 m wide. The leaves are opposite and broadly triangle shaped. They are pale green. The flowers are pink. They are on long stalks.
Inflorescences terminal and axillary, cymose, often aggregated, repeated branching distally and reduction of superior leaves sometimes giving a paniculate appearance, glandular-pubescent, more rarely glabrescent, often viscid; peduncles often stout.
Anthocarps 3–4 × 0.8–1 mm., narrowly fusiform to clavate-fusiform, apex obtuse, glandular-pubescent, rarely glabrescent, ribs 5, smooth, rounded, glandular-pubescent, more rarely glabrescent.
Stems sprawling or ascending to 2–3 (4) m. with erect flowering stems, diffusely branched, sparsely to densely glandular-pubescent, often with interspersed long, septate hairs.
Perianth 1.75–3.5 mm. long, glandular-pubescent, lower portion 5-ribbed, upper portion 0.5–2.5 mm. long, campanulate, white, pink, magenta or mauve.
The W. African specimens differ from typical coccinea in the close pubescence of the stems and the pink (not crimson) flowers.
Stamens (1) 2–3 (4), subequal, exserted 1.5–4.5 mm. long, subequal, exserted.
Flowers 3-many per cluster, subsessile or with pedicels up to 1 mm. long.
Ovary 0.4–0.6 mm. long, glabrous; style 1.3–4.0 mm. long, exserted.
Bracteoles 0.6–2 mm. long, ovate, acuminate, margin fimbriate.
