Herbs, perennial, cespitose, forming domes of rosettes, 15–40 cm. Leaves narrowly to broadly linear, gradually attenuate, 2.5–6(–12) cm. Inflorescences: scape sheaths as long as leaves; scapes filiform, 0.5 mm thick distally, obscurely 4–5-ribbed, pilose from base to apex (s Florida extreme of species glabrous-scaped); mature heads whitish to pale gray, globose to short-cylindric, 4–7(–9) mm wide; receptacle densely pilose; outer involucral bracts becoming reflexed, brownish, oblong to triangular, 1–1.5 mm, apex acute or obtuse, surfaces hairy abaxially and at margins; receptacular bracts dark brown, mostly spatulate, 1.5–2 mm, apex obtuse, distally with white, club-shaped hairs. Staminate flowers: sepals 3, dark brown, narrowly spatulate, 1.5–2 mm, apex acute, abaxially with white hairs; androphore pale, narrowly club-shaped, 1.5 mm, glabrous; stamens 3, appendages 3. Pistillate flowers: sepals 3, pale, oblong to broadly linear, 2 mm (enlarging to 3 mm), apex acute, distal abaxial surface pubescent, hairs white; gynoecium 3-carpellate; stylar column pale, dilated apically, appendages 3. Seeds pale to dark brown, not lustrous, ellipsoid, 0.5–0.55 mm, longitudinal ribs conspicuous, pale, transverse ribs less conspicuous, pattern fine but coarser than in L. beyrichianum.
