Diagnosis:― Sabulina nerimanae is similar to S. gracilis from which differs by it has an annual habit (vs. biennial or perennial), sterile shoots and leaves absent (vs. present in S. gracilis ), sepals 3.5–4.5 mm long (vs. 2.5–3.5 mm), petals oblanceolate (vs. oblong-elliptic), 5.5–6.5 mm long (vs. 3.5–5.0 mm); capsules 5.5–7.5 mm long (vs. 3.2–4.5 mm), as long as or slightly longer than sepals (vs. 1.5 times as long as sepals).
Description:― Annual herb. Stems numerous, ascending or erect, prolifically branching, 5–15 cm long, 0.8–1.0 mm in diameter, radially spreading from the taproot, densely glandular hairy, greenish, nodes 3–7. Sterile shoots and leaves absent. Leaves linear–setaceous, ascending to nearly appressed, 5.0–10.0 × 0.5–0.8 mm, sheath scarious, glandular hairy, 3–nerved (midvein and two lateral), greenish, falcate, margin 0.1 mm membranous, apex acute to acuminate, leaf–fascicles absent. Bracts lanceolate, 2.0–4.0 × 0.7–1.0 mm, glabrous to glandular hairy, 3–nerved (midvein and two lateral), greenish, margin 0.1 mm, membranous, apex acute. Inflorescence terminal and lateral cymes, lax, dichasial, 6–20–flowered, normally also with solitary terminal flowers. Pedicels 7–20 mm long, glabrous or glandular hairy. Sepals lanceolate, spreading–ascending at anthesis, 3.5–4.5 × 1.0– 1.5 mm, glandular hairy, distinctly 3–nerved, greenish, scarious margins ca. 0.1–0.3 mm wide, apex acuminate. Petals oblanceolate, spreading, 5.5–6.5 × 0.8–1.0 mm, 1.5 times as long as sepals, apex rounded, entire to slightly emarginate, base cuneate. Stamens 10, filaments 5–8 mm long, whitish, anthers 0.4–0.5 mm, orbiculate, staminal glands base of outer stamens. Ovary superior,placentation shortly free–central. Styles 2–3 mm, apex rounded, distinct. Capsules ovoid, 4–8–seeded, light green to greenish–tan, 3.2–4.5 × 1.2–1.5 mm, as long as or slightly longer than sepals. Seeds of Sabulina nerimanae are reniform, 4–8 per capsule, with radicle prolonged into rounded bump, 0.3–0.5 × 0.3–0.4 mm, brown, granulate, somewhat compressed, the ventral surface papillate, anticlinal walls are straight, V–undulate, granulate, cells elongated rectangular; the dorsal surface papillate, anticlinal walls are straight, V–undulate, cells rectangular.
Etymology:― The species is dedicated to the eminent botanist Prof. Dr. Neriman Özhatay (Istanbul University, İstanbul / Turkey).
Distribution and ecology:― Sabulina nerimanae grows on stony places (calcareous rocks) at 1320 m a.s.l. in Altınyayla district (Burdur province) ( Fig. 4). Altınyayla district is located in the Mediterranean phytogeographic region. S. nerimanae occurs within open Oak-Juniper woodlands together with Bromus tectorum Linnaeus (1753: 77) , Centaurium erythraea Rafinesque (1800: 75) subsp. turcicum (Velenovskı 1886: 31) Melderis (1972: 232) , Cerastium brachypetalum Persoon (1805: 520) subsp. roeseri (Boissier & Heldreich 1854: 93) Nyman (1878: 109) , Micromeria cristata (Hampe 1837: 233) Grisebach (1844: 122) subsp. phrygia P.H.Davis (1980: 40) , Poa bulbosa Linnaeus (1753: 70) , Saponaria mesogitana Boissier (1843: 16) , Stipa holosericea Trinius (1831: 81) , and Telephium imperati Linnaeus (1753: 271) subsp. orientale (Boissier 1849: 11) Nyman (1879: 254) .
Phenology:― Flowering time June–July, fruiting time July–August.
Conservation status:― Sabulina nerimanae is known only from two population in locus classicus (Altınyayla district, Burdur province). It cover an EOO of about 50 km 2. The number of individuals is approximately 2000. No threat has been observed for the species in the area. Based on available data, it is proposed that the species should be classified as Vulnerable (VU) by the application of the criterion B1a of the IUCN Red List (2014).
