| H. nitidum Willd., Sp. PL 3:1205 (1800-2). Syn: H. cinereo-sericeıım Basiner in Mem. Sav. Étr. Acad. Pétersb. 6:65 (1851); H. calvertii Boiss., Diagn. ser. 2(5):91 (1856)! H. sulphureum Boiss., Diagn. ser. 2(5):91 (1856)! H.basineri Boiss.. Fl. Or. 2:521 (1872)! H. nitidum Willd. var. stenophyllum Boiss., I.e. 519! H. viciifolium Freyn in Bull. Herb. Boiss. 3:266 (1901)! Figure 15, p. 585. Stems procumbent or ascending, (10-)20-40 cm, branched above, with an adpressed sericeous indumentum. Leaves with 4-6 pairs of elliptic leaflets, 8-20 mm long, sericeous on both surfaces, usually denser below; stipules connate, scarious. Peduncles shorter than leaves. Inflorescence ± dense, oblong, scarcely elongating in fruit. Calyx 5-7 mm long with subequal teeth longer than tube. Corolla sulphur yellow, ± persisting in fruit; standard (14-)18-22 mm; wings (13-)17-21 mm; keel (11-)14-17 mm. Ovary glabrous. Lomentum up to 18 mm long with 2-3 segments, c. 5x5 mm, rugose, pubescent, with or without short bristles. Fl. 6-7. Rocky limestone and igneous slopes, sandy places, 1200-2475 m. Type: Armenia, Tournefort (B, Hb. Willd., photo!). Mainly E. Anatolia. A8 Gümüşane: Baiburt to Kop Han, 1520 m, Balls 1505 A! Erzurum: Ispir, Boıırgeau 240 (type of H. nitidum var. stenophyllum)! A9 Erzurum: c. 30 km from Horasan to Tahir, 1930 m, D. 47304! B6 Kayseri: Kayseri to Sivas, 1280 m, Birand 1956:95! Sivas: Gürün to Sivas, c. 1500 m, Hub.-Mor. 12774! B7 Erzincan: Erzincan to Refahiye, 1450 m, Hub.-Mor. 13360! B9 Van: near Van, sandy places, 2200 m, Kronenburg 142! Ağri/Erzurum: Tahir geçidi, between Eleşkirt and Horasan, 2475 m, Karamanoğlu (Hb. Hub.-Mor.). Endemic; Ir.-Tur. element. H. nitidum is characterised by the dense silvery indumentum, the large yellow flowers and the 2-3-segmented lomenta. It is variable in stature and in the size and indumentum-density of the leaflets. Closely allied to H. varium and only clearly distinguished from it by the dense indumentum; some forms of H. nitidum with a sparse indumentum closely approach H. varium. The following two gatherings are anomalous: C4 Konya: Topraksu government station near Karapinar, Ledingham et al. 4363! B5 Nevşehir: Göreme, 1000 m, McNeill 406! They differ from the other specimens of H. nitidum in the smaller (c. 8 x 4 mm), more numerous (up to 12-paired) leaflets, and the pink or purple flowers. Possibly they are extreme ecological forms from very exposed habitats, but field observations are needed. |
