Herbs annual, single-stemmed, 1–2.5 (–4) dm, usually sparsely branched distally; from slender taproot. Stems erect, sometimes laxly so or sprawling, glabrous or puberulent distally. Leaves whorled proximally, alternate distally; sessile or subsessile; blade linear to narrowly spatulate, sometimes scalelike proximally, 4–11 × 0.5–1 mm, base cuneate, apex acute, surfaces glabrous or puberulent, hairs glanduliform (as small glandlike projections less than 0.05 mm). Racemes loosely conic-cylindric to narrowly capitate, 0.7–4 × 0.6–0.9 cm; peduncle usually 3–7 cm; bracts persistent, triangular-ovate. Pedicels 1.5–2 mm, glabrous. Flowers pink or greenish, keel sometimes yellowish distally, 3–4 mm; sepals ovate, 1.1–1.5 mm; wings ovate, oblong-ovate, or ovatelanceolate, 3–4 × 1.3–2 mm, apex acute, short-mucronate, ciliolate on distal margin, hairs sometimes resembling minute, stipitate-glands; keel 2.8–3.8 mm, crest 2-parted, with 2 or 3 entire lobes on each side. Capsules with strongly winged stipelike base, globose, 1.4–2.2 × 1.4–2.2 mm, margins not winged. Seeds 1.2 mm, short-pubescent; aril 1.2 mm, lobes subequal to length of seed.


Phenology: Flowering summer.
Habitat: Wet flatwoods, low pinelands, bogs, savannas.
Elevation: 0–100 m.

Distribution

Ala., Fla., La., Miss., N.C., S.C.

Discussion
