L. corniculatus L., Sp. PI. 776 (1753). Zertova, op. cit. (1967).   Glabrous to pubescent perennial, decumbent, ascending or erect, not stoloni-ferous, stems up to 50 cm, solid. Leaflets (of the main stem) from narrow-lanceolate to lanceolate, oblanceolate or obovate, without evident lateral veins, varying in size. Umbels 1-7-flowered, on peduncles much longer than subtending leaves. Bracts usually 3, narrow and short, about as long as calyx. Flowers (7-)9-13(-15) mm. Calyx subcampanulate. with teeth c. 1-1½ x tube. Corolla about 2 x calyx, yellow to goiden-yellow, often turning green on drying, sometimes red; standard longer than keel and wings, often red-veined: keel strongly arched, with fairly long beak, slightly longer than wings. Legume 15-30 x 1.5-2 mm, straight, terete. 2/7 = 12, 24. Fl. (4)5-8(9).   The almost impossible task of the division of the L. corniculatus complex has been pointed out repeatedly. Many botanists have subdivided it into a large number of species which differ only very little from one another. Here L. corni-culatus is treated as a polymorphic species comprising a spectrum of different forms that can be provisionally grouped under three varieties, connected by intermediates. All three varieties occur in the Euro-Siberian, Mediterranean and Irano-Turanian regions, but usually grow in different habitats. 1. Upper leaflets obovate, obtuse or apiculate; umbels 2-7-flowered; flowers 8-15 mm; stems sturdy    2. Stems up to 20 cm; leaflets small, not exceeding 7 x 3 mm, usually ± densely hairy; umbels (l-)2-4-flowered; flowers 8-11 mm var. alpinus    2. Stems more than 20 cm; leaflets larger, usually sparsely hairy or subglabrous; umbels usually (3-)4-7-flowered; flowers 10-15 mm var. corniculatus 1. Upper leaflets narrowly oblong or oblanceolate, often subacuminate; umbels l-3(-5)-flowered; flowers 7-10 mm; stems slender var. tenuifolius var. alpinus Ser. in DC., Prodr. 2:214 (1825). Syn: L. alpinus (Ser.) Schur, Enum. PL Transs. 160 (1866); L. corniculatus L. var. brachyodon Boiss., Diagn. ser. 2(2):21 (1856)! Ic: Zertova in Öst. Bot. Zeitschr. 111:337-344 (1964); Bonnier, Fl. Comp. Fr., Suisse et Belg. 3: t. 142 f. 766 (1914). Fl. (5-)7. Rocky slopes and alpine pastures, (450-)1200-2500 m.   Described from the Alps.   Type: Schleicher, Centuria exs. n. 75.   Scattered in mountain areas of Anatolia.

Some doubt remains as to whether these Turkish specimens can be equated with the Euro-Siberian mountain variety, though there is much similarity between them and both are diploids (2n = 12). Specimens with short calyx teeth have sometimes been distinguished as var. brachyodon Boiss. As treated here, var. alpinus probably comprises a series of high altitude forms derived from different populations of var. corniculatus sensu lato.   Distribution of species: Europe, N. Africa, W. & C. Asia.
