Silene scoparia differs from S. oreoploca Lidén in its longer and narrower flowers

(22–27 mm vs 15–20 mm long), longer androgynophore (13–16 mm [13–19 mm in fruit] vs 8–10 mm [8–14 mm in fruit]) and calyx teeth scabrid by antrorse acute projections abaxially (vs glandular hairy). – Type: Nepal, Dolpa , Ankhe to Dunai (29°N, 82°50′E) GoogleMaps ,

2750 m, fl. pink – white, 10 x 1991, M. Minaki et al. 9104467 (holotype E00232987 ; isotypes TI 9104467 , TUS). Figures 1A–I View Figure 1 , 2 View Figure 2 .

Silene moorcroftiana ” sensu Rajbhandari & Suzuki (2008) View in CoL p.p., non Benth. (1839).

Densely caespitose perennial forming bright green tufts or tussocks in cliff crevices. Root (rarely present in herbarium specimens) crowned by a cluster of several perennating stems, ending in small secondary crowns, each with a terminal rosette subtended by stramineus coriaceous residues of old petiole bases, the latter with minute antrorse marginal setae and persistent midvein. The rosettes are overgrown by flowering stems emerging from below the rosette, up to 15 from each terminal crown and up to 100 per plant. Stems ascending from base, 8–30 cm long, with 8–20 nodes evenly distributed, simple or with small leafy branches, with retrorse acute hairs (0.05–0.1 mm long) throughout, and with scattered glandular hairs (0.1–0.2 mm long) in upper part. Rosette leaves linear to very narrowly oblanceolate, 20–35 mm long. Cauline leaves linear, acute, 10–30 × 1–2 mm, thickish,

stiff, with antrorse-scabrid margin and midvein, otherwise glabrous. Uppermost leaf pair (bracts) usually smaller. Inflorescence terminal, 1(–3)-flowered; axillary 1-flowered branches sometimes grow from upper leaves. Pedicels 1–10(–20) mm. Bracteoles minute when present. Flowers erect or often slightly oblique. Calyx 22–27 mm long, with narrow often slightly curved basal half; veins distinct, green or brownish purple, without anastomoses, with very stout broad-based glandular hairs 0.2 mm long. Calyx teeth 2.5 mm long with distinct claw and rounded limb, abaxially scabrid from antrorse acute projections; margin ciliate. Androgynophore 13–16(–19) mm long, finely and densely retrorse-hairy. Petal claw exserted, narrowly obtriangular. Petal limb c. 10 mm long, white or pale purple, obtriangular, divided to 1/3. Coronal scales white, narrow, 1.5 mm long. Anthers exserted. Styles 3, exserted. Seeds rounded-reniform in profile, c. 1.4 mm, with obtuse back with long thin papillae.

Distribution. Endemic to Nepal (Southeast Dolpa and Mustang).

Habitat and ecology. Cliff crevices. Altitudinal range 2600–3100(–3700) m. Flowering late July to October.

Etymology. From Latin scopa (broom made from thin twigs).

Notes. The related Silene oreoploca is also found in Mustang but at higher altitudes (see Table 2 for distinguishing characters).
