Trigonella selcuk-bayraktarii İlçim sp. nov. ( Figs 1–6 )

Type:— Turkey, Kahramanmaraş, around Çamlıbel village , 650–700 m, 18.04.2018, A.İlçim 2080 (Holotype MKUH!; syntypes ANK!, GAZI!) .

Syntypes: —Mustafa Kemal Univ. Herb., ANK . Paratypes: Turkey, Kahramanmaraş Fırnız valley , steppe, 700–750 m, 19.04.2018, A.İlçim 2081 (Mustafa Kemal Univ. Herb.) .

Diagnosis:— Trigonella selcuk-bayraktarii is closely similar to T. kotschyi and T. cilicica , but it differs from them by its bigger glabrous, obcordate, emerginate and mucronate, 10–20 x 6–18 mm leaflets (neither subadpressed hairy, oblong, obobavate, cuneate, 4–10 x 2–10 like in T. kotschyi nor sparsely pilose, oblanceolate, broadly obovate-cuneate, 2–8 x 1–10 mm like in T. cilicica ), Inflorescence Umbellate, 4–5(–6) flowered (neither short raceme, 6–13 flowered like in T. kotschyi nor lax capituliform raceme, 4–15 flowered in T. cilicica ), legume 30–50 × 1–1.5 mm, glabrous (neither 7–25 mm, adpressed hairy like in T. kotschyi nor 4–7 mm, adpressed hairy like in T. cilicica ).

Description:— Annual herbs, stems ascending, 8–30 cm, branched from base; lower parts reddish-brown; sparsely hairy. Leaves 4–4.5 cm, petiole 2–2.2 cm, trifoliate, Leaflets glabrous, broadly obdeltoid to obcordate, emerginate, mucronate, denticulate at apex, lower leaflets sessile, 10–15 × 6–9 mm, terminal leaflets larger than laterals 13–20 × 11–18 mm, 4–5 mm petiolulate. Stipules adnate to petiole, narrowly triangular, terete, 5–6 mm. Flowers axillary, umbellata, 11–12 mm long, 4–5 (–6). Peduncle aristate, 17–25 mm, shorter than leaves. Pedicels 2–2.5 mm sparsely pilose. Calyx reddish in fruit and bud green in flower, campanulate, 4–5 mm long; teeths unequal, lower teeths 1.5 mm, upper teeths 2–2.2 mm, triangular - acuminate, shorter than or as long as tube, glabrous or few hairs. Flowers white, 10–11 mm. Standart 10–11 mm, obovate, emerginate, wings 10–11 mm, keel 7–8 mm. Legumes linear, glabrous, somewhat compressed, falcate to semi¬circular, smooth, shortly beaked, 30–50 × 1–1.5 mm green sometimes stained reddish. Seeds oblong-cylindrical. Fl & Fr. 4-5. Steppes.

Etymology:— The specific epithet is derived from the name of Selçuk Bayraktar who is Turkish engineer and the architect of Turkey’s first indigenous unmanned combat aerial vehicle and first unmanned fighter jet Bayraktar Kızılelma.

Distribution and habitat: Trigonella selcuk-bayraktarii is known from two localities in Kahramanmaraş city. This species is known only from the province of Kahramanmaraş. It is thought that the species may spread in neighboring provinces. Kahramanmaraş province includes Mediterranean and Iran-Turan phytogeographic regions. This new species is located in the Irano-Turanian phytogeographic region. The distribution altitudes of the species vary between 650 m and 750 m.

The significant taxa that grow and distributed sparsely on the steppe areas are: Rheum ribes L, Salvia marashica İlçim et al. , Ornithogalum alpigenum Staph , Conringia perfoliata (C.A. Meyr) Busch, Cinicus benedictus L. var. benedictus , Cruciata taurica (Pallas Ex Willd) Ehrend. , Scorzonera mollis Bieb.subsp. mollis , Serratula serratuloides (DC) Dakht , Teucrium multicaule Montbret & Aucher Ex Bentham , Vicia hybrida L., Vicia galilaea Piltm & Zoh. , Fontanesia philliraeoides Labill philliraeoides , Bellevalia longipes Post , Muscari comosum (L.) Miller, Lepidium draba (L.) Desv. subsp. chalapensis , Silene dichotoma Ehrh. subsp. dichotoma .

Consevation status

T. selcuk-bayraktarii is an endemic species to Kahramanmaraş province. It is known with small populations from two localities in the province. Goat breeding is carried out in the areas where the species is distributed. The species must be monitored for conservation status.
