Perennial or biennial glabrous herbs, with erect, nearly or quite simple stems, and narrow leaves, the basal densely tufted, those of the stem sessile, and small red to rarely white flowers in clustered terminal cymes, the inflorescence in our species almost capitate. Calyx oblong-campanulate, not inflated, 4-5-toothed, 8-10-ribbed. Petals 4 or 5. much exceeding the calyx, each with a 2-cleft appendage at the base of the obovate emarginate blade. Stamens 10, exserted. Styles opposite the calyx-teeth, alternate with the petals. Capsule several-celled at the base, its teeth as many as the styles. [Latin, glutinous.]
