Plants perennial, loosely cespitose; taproot stout; caudex branched, woody, bearing tufts of leaves. Stems not much-branched, slender, (15-)30-60 cm, sparsely pubescent proximally, viscid-glandular distally. Leaves mostly basal; blade linear-lanceolate to oblanceolate, 2-8 cm × 2-6(-15) mm (including petiole), base tapered into slender petiole, apex acute to obtuse, subglabrous to glandular-pubescent on both surfaces; cauline leaves to 4 pairs below inflorescence, narrower than basal leaves, blade usually linear but rarely elliptic-lanceolate. Inflorescences erect, with several short, ascending branches, few-flowered, open, bracteate, shortly pubescent and viscid-glandular; bracts narrowly lanceolate, 3-10 mm, rigid. Flowers: calyx prominently 10-veined, broadly tubular, umbilicate, moderately or not clavate, narrowed around carpophore, lobed, 12-15 × 4-6 mm, thin and papery, with short glandular-viscid pubescence, veins parallel, usually red pigmented, with pale commissures; lobes lanceolate, 2-4 mm, apex acute; petals white, pink, or dingy red, 1 1/2-2 times calyx, claw equaling calyx, ciliate at base, limb obtriangular, 4-6 mm, deeply divided into 4 linear lobes, appendages 2, conspicuous, laciniate, 2-3 mm, apex rounded; stamens slightly exserted; filaments ciliate at base; styles 3(-4), equaling or longer than stamens. Capsules 1-locular, narrowly ovoid, exceeding calyx, opening by 6 (or 8) ascending teeth; carpophore 3-6 mm. Seeds brown, reniform, 1.5-2 mm broad, shallowly tuberculate on both surfaces, papillate around margins. 2n = 48.
