Densely caespitose perennial, forming tufts or tussocks, bright green, with thick rootstock with several short perennating stems ending in dense leaf rosettes surrounded at base by tough, long persistent, stramineus residues of old petiole bases with stiff antrorse marginal setae. Flowering stems (3–) 7–20 cm long, simple or branched, with (4–)7–12 nodes, densely pubescent with stout patent glandular hairs 0.2–0.3 mm long in upper part, below with reflexed eglandular hairs 0.1–0.2 mm long. Leaves of non-flowering rosettes narrowly linear-oblanceolate, 20–35 mm long. Cauline leaves linear, acute, 10–30

× 1–2 mm (uppermost leaf pair [bracts] sometimes smaller), thickish, stiff, glabrous, more or less antrorse-scabrid, bright green, sometimes bluntly purple-mucronate. Inflorescence terminal 1(–3)-flowered; 1-flowered lateral branches may grow from upper axils. Pedicels 1–10(–20) mm long. Bracteoles (if present), and sometimes bracts, minute. Flowers erect. Calyx 14–20 mm, gradually attenuate from middle to base; veins distinct, green or purple, without distinct anastomoses, with stout glandular hairs 0.2–0.3 mm long. Calyx teeth

2 mm, purplish, rounded, constricted at base, with broad scarious ± lacerate-dentate and ± ciliate margin, abaxially with glandular hairs. Androgynophore 8–10 mm (to 14 mm in fruit) long, finely retrorse-pubescent with acute hairs. Petal claw exserted; limb c. 10 mm, white or pale purple above, reddish below, obtriangular, divided to 1/3, rarely with a small basal sharp tooth on each side; coronal scales white, narrow, 1–1.5 mm. Styles 3. Seeds rounded-reniform in profile, 1.2 mm long; back very broad with prominent papillae.

Distribution. From Kumaon to the Mount Everest region.

Habitat and ecology. Rock crevices, among boulders, on gravel. Altitudinal range

3400–4800 m. Flowering June to October.

Etymology. From Greek ὄρος (‘mountain’) and πλΌΚα (‘tuft’).

Notes. The type collection of Melandrium linearifolium consists of disconnected shade-grown stems with flowers in bud stage. Hence, Zhou overlooked the identity of this plant with her “ Silene caespitella ”.
