Basionym: Melandrium nyalamense L.H.Zhou, Fl. View in CoL Xizang. 1: 727 (1983). – Type: Tibet, Nyalam , 4000 m, 5 ix 1972, Tibet herbal medicine census 1832 (holotype HNWP 30689 About HNWP , isotype PE 00558365 ). Figure 5A–G View Figure 5 .

Melandrium cashmerianum ” sensu Zhou (1983) View in CoL and “ Silene cashmeriana ” sensu Zhou et al. (2001 View in CoL p.p, non Silene cashmeriana (Royle ex Benth.) Majumdar View in CoL ).

Rootstock stout, vertical. Stems above with dense glandular and eglandular hairs, lower half with only eglandular recurved hairs or subglabrous. Flowering stems few to several, erect, 20–40 cm, with 5 or 6 pairs of leaves, simple or branched. Leaves green or greyish green with distinct midvein; lowermost leaves petiolate, often withered at flowering time, middle and upper leaves sessile. Lower and middle leaves elliptic to oblanceolate, acute to usually slightly acuminate, 20–50 mm long, 5–15 mm broad, sparsely to densely hairy (always dense on midvein and margin), with short hairs 0.1–0.15 mm long (longer cilia towards the base). Upper leaves sessile, lanceolate, 20–40 × 4–10 mm. Inflorescence terminal

3- to 5-flowered; axillary 1- to 3-flowered. Bracts like uppermost leaves or smaller, densely ciliate; bracteoles minute. Flowers ± nodding. Pedicels 2–5 mm long, or up to 11 mm in alar flowers. Calyx campanulate, 9–10 × 5–6 mm, divided to 1/3, with prominent dark purple veins coming together at teeth apices, lateral anastomoses absent; densely hairy with ± broad-based acute hairs 0.3 mm long, at least some gland-tipped. Teeth triangular, subacute, slightly constricted at middle, ± recurved and slightly folded at apex, densely ciliate with thin hairs 0.3 mm long. Androgynophore c. 1 mm long, densely hairy above, less so below. Petal claw slightly exserted, 3 mm broad at apex, slightly dentate, slightly auriculate; limb 1.5–2 × 1.5 mm, bifid to 1/3 to 1/2; coronal scales 0.5–1 mm long. Styles 5 (described as 3-styled in the protologue, but this is obviously a lapsus calami). Seeds 0.8 mm long, tuberculate, with longer papillae on back.

Distribution. East Central Nepal and South Tibet (Gyirong, Nyalam).

Habitat and ecology. Open places. Altitudinal range 3500–4100 m. Flowering July to August.

Notes. Silene nyalamensis can be confused with S. procera in bud or if shade-grown, but the latter is a taller plant with thin erect branches, has a larger more rounded calyx with softer less tapering hairs and greenish reticulate veins, and grows at lower altitudes. Small individuals of Silene nyalamensis are similar to S. blepharicalyx , but in this case (like in S. procera ) the calyx veins are less raised and have at least some reticulations; further, glandular hairs are lacking, and the calyx teeth have longer cilia.
