( Fig. 2–4 ). Type : [ Turkey C 3 Antalya ] Gebiz district, Bozburun Mountain (Part of the Toros Mountains), between Boğazağzı- Tozluçukur plateu, 1500 m , 18.06.2015 , 37 o 20’N- 31 o 02’E , M .Koç 2690, Hamzaoğlu & Budak ( holotype GAZI , isotype ANK , GAZI , HUB ). Diagnosis:— Minuartia torosensis differs from Minuartia meyeri in having inflorescence 9–15-flowered (not 3–6- flowered), alar pedicels longer than sepals (not 1/2–1/3 as long as sepals), sepals smooth (not carinate), acuminate at apex (not long acuminate), capsule 4–5 mm long (not 2–3 mm long), ovoid (not subglobose) and 2/3 as long as sepals (not 1/2–1/3 as long as sepals), seeds ventral and dorsal surface with tubercles (not ventral surface with smooth tubercles and dorsal surface with papillate) ( Table 2 ). Description:— Annual herb. Stems erect, 3.5–10 cm long, 0.8–1.2 mm diam., puberulent below, glandular-pubescent above, greenish, 2–5-noded. Leaves linear-lanceolate, 9–24 × 1–1.7 mm , glabrous or glandular-pubescent, prominent 5–7-veined, greenish; herbaceous at margine and 0.1 mm ciliate; acute at apex; sheath membranaceous, 0.5–2. 0 mm, puberulent or glanbular-pubescent. Inflorescence 3–6-flowered, flowers pedicellate, loose, overlapping, dichasial clusters, densely glandular-pubescent, greenish. Bracts linear-lanceolate, 7–14 × 1–2 mm , shorter or as long as the clusters, densely glandular-pubescent; acute at apex. Pedicels 1-3 mm , erect at flowering time, densely glandular-pubescent. Sepals triangulare-lanceolate, outher sepals 4.0–6.5 × 1.0– 1.3 mm , inner sepals 3.5–6.0 × 1.0– 1.2 mm , densely glandular-pubescent, prominent 3-veined, greenish, carinate, not equal; membraneous at margine, glabrous, long acuminate at apex; petals eliptic, 1–2 × 0.6–1.0 mm, 1/3–1/4 as long as sepals, white; cuneate at base; widely acute at apex. Stamens 10; filaments 1–1.5 mm long; staminal glands unclear, 5-numerous, positioned at the base of outer filaments, white. Styles 4–6 mm long. Capsule subglobose, 2–3 × 1.0– 1.7 mm , 5–7-seeded, 1/2–1/3 as long as outher sepals, cartilaginous. Seeds globose or reniform, 0.7–1.0 × 0.7–0.9 mm , granulate, brownish; ventral surface smooth tuberculate; dorsal surface papillate. FIGURE 1.

Scale bars: 1 and 4 = 100 μm; 2, 3, 5, and 6 = 20 μm. Etymology:— The specific epithet is derived from the locus classicus, Toros mountains. Proposed vernacular name:— “Toros yıldızı” (Turkish), “Taurus star” (English). Phenolgy: —Flowering time June, fruiting time July–August. Distribution and Habitat:— Minuartia tortumensis occurs on the Bozburun Mountain ( Antalya ) and it can be considered as endemic to Turkey where it grows on calcereous rocks, at 1500 m a.s.l. Conservation status:— According to the available data, Minuartia torosensis grows in an area of approximately 1000 km 2 covering the Gebiz districts of Antalya province . The species, which has a discontinuous distribution, has been reported in only one localite in Antalya . Because of overgrazing, the habitat of this species is under threat, and destruction of the species is leading to the reduction in the number of plants. For that reason, it is proposed that the species should be classified as Endangered (EN) according to the International Union for Conservation of Nature (IUCN 2012), criterion B1a.
