Zhou; Silene maheshwarii Bocquet. Plants 13–40(–60) cm tall. Roots robust, vertical, lignified. Stems caespitose, erect, green, shortly retrorse-pubescent throughout. Basal and proximal cauline leaves green on both surfaces, linear, 4–7(–10) cm × 2–5 mm, margin ciliate, midvein prominent, hairy only at veins or glabrous, base narrow, apex acute; distal leaves 3 or 4 pairs, sessile, linear, gradually reduced upwards. Flowers to 20, in an irregular thyrsoid with long-and shortly stalked (1–)3–5-flowered cymules, sharply nutant, becoming erect in late anthesis. Pedicel short. Calyx narrowly cylindric-campanulate, soon becoming broader as capsule swells, 5–7 × 2.5–3 mm, rounded at base, open at apex, weakly hairy, veins dark green to blackish red; teeth triangular, ca. 2.5 mm, margin membranous, ciliate, apex acute. Androgynophore ca. 1 mm, sparsely villous. Petals exserted 1–2 mm beyond calyx, dark red, rarely greenish white; claws cuneate, ca. 6 mm, glabrous at base, conspicuously auriculate (2.5–3 mm wide at apex); auricles ciliate; limb 1–2 mm, shallowly bifid, usually with small lateral lobes; coronal scales small. Stamens included. Styles included. Capsule globose, ca. 8 mm, slightly longer than calyx. Seeds gray, globose-reniform, ca. 0.8 mm, minutely tuberculate. Fl. Jun–Jul, fr. Aug–Sep. Alpine forests, alpine meadows; 2500–5100 m. SE Qinghai, SW and W Sichuan, S and SE Xizang [Bhutan, Kashmir]. This species is closely related to Silene nepalensis, from which it differs in its linear leaves and smaller flowers. Silene caespitella is a very homogeneous species throughout its range.
