 Type:— TURKEY C 4 Konya: Hadim district, Taşkent to Alanya road, Gevne valley, northeast side of Yalnızardıç Dam lake, Küçüklü village, roadside, 1600 m, 5 September 2014, A. E. Yaprak, B. Akyıldırım, and İ. Başköse 2656 (holotype ANK!, isotypes ISTF!, ANK!).   
 Diagnosis: — Hedysarum ketenoglui is similar to Hedysarum anatolicum in life form (perennial) inflorescence, bract, bracteole, calyx and corolla structure, and seed form, but can be distinguished by habitus (erect-ascending or erect versus procumbent), stem (20–60 cm versus 6–35 cm), leaves (upper stem leaves 4–6 cm, middle and lower leaves 7–15 cm versus all leaves 1.5–4(–5) cm) and peduncle length (5–40 cm versus (3–)6–10(–18) cm), leaflets (leaves with 1–4 pairs lateral leaflets versus 2–3(–4) pairs lateral leaflets), stipule (5–10 mm versus 3–5 mm), number of flowers in the inflorescence (20–30-flowered versus 8–20-flowered), and relatively larger fruits in Hedysarum anatolicum.   
 Description:— Perennial, half-shrub with woody rootstock, Whole plant pilose hairy (except corolla and stamens). Stem long, 20–60 cm, erect-ascending or erect, caespitose, lateral branched, cylindrical, angular or sometimes slightly sulcate. Leaves petiolate, petiol angular or sulcate, imparipinnate, rarely paripinnate, upper stem leaves 4–6 cm, middle and lower leaves 7–15 cm, with 1–4 pairs lateral leaflets, stipulate, stipules united 2-toothed, scariose; leaflets stalked or subsessile, up to 0.5–2 mm, entire, obtuse, mucronate or slightly emarginate, cuneate or obtuse at base; lateral leaflets variously, obovate, elliptic, sometimes ovate and orbicular, rarely oblanceolate, 7–35 × 5–20 mm; terminal leaflets obovate, sometimes orbicular, rarely ovate or oblanceolate, 9–35 × 5–25 mm, larger than lateral leaflets. Inflorescence axillar, racemose, long ovate-oblong, 2–5 cm, 20–30-flowered. Peduncles, at flowering 5–20 cm long, at fruiting up to 40 cm and conspicuously longer than leaves; pedicels 1–3 mm long, at fruit 5 mm long, recurved. Bract and bracteole present; bract 1, ovate or lanceolate-subulate, 1.5–4 mm, deciduous, out surface hairy; bracteole 2, small, subulate, 0.5–2 mm. Calyx united 5 toothed, 4–8 mm long; tube 1.5–2.75 mm, teethes 2–5.75 mm, subulate, deltoid, teethes longer than tube or rarely equals. Corolla pink, when dry purple, 14.5 mm long, glabrose, standard 10–14.5 mm, obovate or oblanceolate, emarginate; wings 6–9 mm, obtuse; keel 9–13.5 mm, truncate. Stamen diadelphous, 11.5–15 mm; filaments milk-white, 9–14.5 mm; anthers yellow, 0.35–0.65 × 0.15–0.30 mm, elliptic or ovate. Pistil 1, 2-carpelled, 1-locular, 11.5–16 mm; ovary elliptic, hairy; stigma sessile; style long, filiform. Fruit, not-segmented legume, deciduous, stipitate, (15–)20–45 × 7–15 mm, 2–3 seeded, sometimes 1, 1-seeded fruit pyriform; surface clearly reticulate veined and adpressed hairy, attenuate at base. Seed brown, 3.5–7 × 2.5–5.5 mm, ovate or reniforme, rarely rounded, surface smooth.   
 Habitat and Ecology: — Hedysarum ketenoglui is an endemic species with an eastern Mediterranean element. The species was observed in 3 different localities in Gevne valley.Apparently, their distribution area is less than 10 km ² and the total number of observed individual plants is ca. 500. The species grows on sparsely wooded calcareous red soil, at 1400–1600 elevation. It is found together with Chrysopthalmum gueneri Aytaç & Anderberg (2001: 211), Paliurus spina-christi Miller (1768: 8), Onobrychis montana Candolle (1805: 611), Onobrychis armena Boissier (1856: 36) and Centaurea drabifolia Smith (1813: 202).   
 Phenology: —Flowering in June–July, and fruiting in August–September.   
 Proposed Turkish name for the new species: —gevne pisiktaşağı   
 Etymology: —The new species is named in honour of the eminent Turkish botanist and ecologist Professor Osman Ketenoğlu (Ankara University, Faculty of Science, Department of Biology).
