Diagnosis:— Salvia adiyamanensis is closely similar to S. cassia and S. cilicica , but it differs from them by its loosely branched and smaller stems 20–70 cm long (neither 40–90 cm like in S. cassia nor 30–120 cm like in S. cilicica ), smaller palmately veined leaves 3–4× 3.5–4 cm (neither pinnately veined, 2–10× 3–11 cm like in S. cassia nor pinnately veined, 2–10.5 × 3–11 cm in S. cilicica ), bigger dark purple, broadly ovate acuminate bracts, 7–18 × 5–15 mm (neither light purple or yellowish narrowly ovate acuminate bracts and 3–7× 2.5–6 mm like in S. cassia nor yellowish narrowly ovate acuminate bracts, 2.5–4 × 2–3 mm like in S. cilicica ), dark purple to yellowish calyx, 10–11 mm long in flower and to c. 14 in fruit (neither light purple or yellowish 7–12 in flower and to 14 mm in fruit like in S. cassia nor 5–8 in flower and to 9 mm in fruit like in S. cilicica ), and smaller corolla 13–22 mm and maroon lower lip (neither 20–30 mm and yellow lower lip like in S. cassia and 14–20 (–25) mm in S. cilicica ). Description:— Perennial herb. Stems ascending to erect, 20–60 cm , unbranched or loosely branched, pannose to ± lanate below, very shortly pilose with capitate glandular hairs above. Leaves simple, ovate and palmately veined, 3–4 × 3.5–4 cm , pannose, serrulate, cordate or not; petiole on lower leaves 2–4 cm , upper leaves sessile. Inflorescence simple, unbranched, or loosely branched, 10–20 cm , shortly eglandular and glandular pilose; verticillasters 2–6- flowered, clearly distant. Bracts ovate acuminate, green to dark purple, 0.7–1.8 × 0.5–1.5 cm , shortly eglandular and glandular pilose, shorter than calyx. Pedicels 1–2 mm . Calyx tubular campanulate green, later purplish, striate, 10–11mm , to c. 14 mm in fruit, shortly pilose with sessile glands; upper lips tridentate, recurved in fruit, mucronate. Corolla 13–22 mm , upper lip and wings of lower lips white, sometimes bluish tinged, middle lower lip maroon with yellowish border, tube c. 5–7 mm , ventricose, squamulate; upper lip clearly falcate, emerginate. Theca ca. 4–5 mm , filaments 8–11 mm , stylus 20–21 mm long, hirsute, exerted from corolla lips and divided in two parts at apex. Fl.May. Etymology:— The specific epithet is derived from the name of Adıyaman province , where the specimens were collected. Conservation status:— The new species is only known from Adıyaman province , south-eastern Anatolia , Turkey , and belongs to the Irano-Turanian phytochorion. We recommend that the threatened category of Salvia adiyamanensis should be “Critically Endangered ( CR )” (criteria B2 a b (i, iii) of IUCN 2017 ). Because of the occurrence area estimated less than 100 km 2 . The distribution area of the species has high grazing pressure. Ecology:— The significant taxa that grow and distributed sparsely on the serpentine areas are: Cyathophylla viscosa (C.A.Mey.) Madhani & Rabeler , Stachys ramosissima Montbret & Aucher ex Benth. , Melica persica Kunth subsp. persica , Paronychia kurdica Boiss. var. kurdica , Avena sterilis L. subsp. sterilis, Klasea oligocephala (DC.) Greuter & Wagenitz, Centaurea urvillei DC. subsp. armata Wagenitz , Chardinia orientalis (L.) Kuntze, Gundelia tournefortii L., Quercus brantii Lindl. , Q. infectoria G.Olivier , Prunus arabica (Oliver) Meikle , Crataegus orientalis Pall.ex M.Bieb. subsp. orientalis, Paliurus spina-christi Mill.
