Habit | Plants annual; taproot slender. | Plants perennial, viscid; taproot stout; caudex branched, woody, producing several to many shoots. |
Stems | erect, branched, rarely simple, 15–45 cm, with long, often crinkled hairs mixed with short pubescence, viscid-glandular distally. |
erect, branched, leafy, 20–60 cm, villose-tomentose, viscid-glandular. |
Leaves | 2 per node, blade with coarse, ascending, scabrous pubescence on both surfaces; basal few, withering, blade oblanceolate to spatulate-petiolate, 0.5–5 cm × 3–15 mm; cauline blades oblanceolate to lanceolate, 1–7 cm × 1–15 mm, apex obtuse or shortly acuminate to acute. |
2 per node, connate proximally, sessile, largest in mid stem; blade lanceolate, 3–7 cm × 5–15 mm, apex acute, glandular-tomentose throughout. |
Inflorescences | open, with racemose branches, internodes and bracts usually ca. equaling fruiting calyx, 1–5 mm, longer proximally. |
open, leafy cymes, bracteate, viscid and glandular-tomentose, branches ascending, mostly floriferous, flowers terminal and at distal nodes; bracts leaflike, 5–30 mm. |
Pedicels | shorter than calyx. |

Flowers | 5–8 mm diam.; calyx prominently 10-veined, narrowly tubular-ovoid in flower, ovoid in fruit, constricted at mouth, 7–10 × 3–5 mm, membranous between veins, margins dentate, hispid, hairs ca. 2 mm, veins parallel, lobes lanceolate, 2–2.5 mm, apex greenish purple, acute; petals white or pink, often with dark spot or dark pink throughout, clawed, claw equaling calyx, limb elliptic to obovate, lobed or unlobed, to 6 mm, appendages 2, oblong to narrowly lanceolate, 1–1.5 mm; stamens equaling or shorter than calyx; stigmas 3, included in calyx. |
calyx obscurely 10-veined, tubular-campanulate, 10–15 × 4–5 mm in flower, becoming clavate and 15–20 × 6–8 mm in fruit, narrowed toward base around carpophore, herbaceous, viscid-pubescent, veins more distinct at base, without conspicuous pale commissures, lobes narrowly lanceolate, 3–6 mm, margins very narrow, membranous, apex blunt; corolla greenish white, clawed, claw equaling calyx, widened distally, limb emarginate, 2 × 4 mm, appendages 4(–6), ca. 0.5 mm; stamens equaling petals; styles 3, equaling petals. |
Capsules | equaling calyx, opening with 6 recurved, narrowly triangular teeth; carpophore shorter than 1 mm, pubescent. |
ellipsoid, slightly longer than calyx, opening by 6 teeth; carpophore 1.5–2.5 mm. |
Seeds | dark reddish brown, reniform, angular with concave, radially ridged faces, broad outer edge transversely ridged and verrucose, ca. 0.5 mm broad. |
yellowish brown, winged, reniform, ca. 2 mm, rugose; wing broad, wrinkled. |
