Thomas Cheeseman published this description posthumously in 1925 (measurements converted to metric): Stems densely tufted, very variable in size, usually from 6–12 in (150–300 mm), but sometimes attaining 18 in.

Leaves radical and a few cauline, all much shorter than the stem, 1–6 in (25–152 mm) long, rarely more, 0.1–0.25 in (2.5–6.4 mm) broad at the base and from thence gradually tapering upwards, apex subulate, not obtuse as in the forms of L. campestris; margins flat or involute, ciliate with long hairs.

Inflorescence terminal, erect or nodding, compound, of several short and dense spikes either all congested into an ovoid head, or the lower 1 to 3 distinct and sometimes peduncled.

Lower bracts foliaceous, often overtopping the inflorescence; upper membranous, with very broad white margins and apices, densely ciliate with long hairs.

Perianth-segments equal, or the outer slightly longer, lanceolate, awned, pale-chestnut with white and silvery margins.
