Plants perennial, cespitose, forming small mats or cushions, glandular-pubescent or glabrous. Stems ascending to spreading, frequently purple tinged, many-branched, not filiform. Leaves: axillary fascicles absent; basal not in primary rosettes, secondary rosettes usually present, blade linear to linear-subulate, 2–13 mm, not fleshy, apex apiculate to acute, glabrous; cauline connate basally, forming shallow, often purplish, scarious cup, blade with frequently conspicuous midvein, subulate, 3–9(–12) mm, becoming shorter toward apex, not fleshy, apex apiculate to acute, glabrous. Pedicels filiform, glandular-pubescent, rarely glabrous. Flowers terminal, 5-merous or 4- and 5-merous; calyx base glandular-pubescent or glabrous; sepals broadly ovate to lanceolate, 2–2.5 mm, hyaline margins usually purple tinged, at least at apex, apex obtuse to somewhat acute, glandular-pubescent or glabrous, remaining appressed after capsule dehiscence; petals elliptic to narrowly obovate, 2.5–3 mm, longer than or seldom equaling sepals; stamens 8 or 10. Capsules 3–3.5 mm, exceeding sepals, dehiscing to base. Seeds brown, obliquely triangular with abaxial groove, 0.5 mm, lateral surfaces frequently with elongate ridges, abaxial surface appearing smooth to pebbled.
