A. jodostachys Boiss. & Buhse in Nouv. Mem. Soc. Nat. Mosc. 12:60 (1860).
Erect, caulescent perennial, 25-30 cm. Leaves 3-7 cm; leaflets 6-15 mm, linear-lanceolate to linear-oblong, subacute, sparsely adpressed bifurcate-hairy, 5-12-paired; stipules to c. 5 mm, triangular-acuminate, united at the base. Inflorescence c. 2.5 x 1.5 cm, oblong, a lax, 10-20-flowered raceme, much elongating in fruit; flowers subsessile. Bracts c. 1.5 mm, linear to lanceolate. Calyx c. 8 mm, tubular-campanulate, sparsely adpressed black and white bifurcate-hairy; teeth 1-2 mm. Corolla violet: standard 17-20 mm. Legume 25-30 x c. 3 mm, straight or incurved, spreading or pendulous, constricted between the seeds, sparsely adpressed black and white, bifurcate-hairy; beak c. 2 mm, curved. Fl. 6. Rocks, igneous slopes, 1870-2140 in.
Type: [N.W. Iran] prov. Adserbidshan prope Livan et Montem Sähend, Buhse 464 (iso. K!).
N.E. Anatolia. A9 Kars: 26 km from Benliahmet to Kağizman, 1870 m, D. 46647!
N.W. Iran. A specimen from B9 Van (3 km from Gevaş to Van, 1700 m, Hub.-Mor. 11430!) approaches A. stevenianus var. kochianus in that its calyx teeth are c. 4 mm long, but agrees with A. jodostachys in having leaves with c. 9 pairs of leaflets and some fruits predominantly black-hairy.
Sect. Onobrychium Boiss. (incl. Sect. Asciocalyx Bunge). Caulescent, herbaceous, perennial herbs. Leaves imparipinnate: leaflets bifurcate-hairy; stipules united, free from the petiole. Inflorescence a pedunculate, many-flowered raceme or spike. Flowers ebracteolate. Calyx black and white, simple- and bifurcate-hairy, rarely inflated in flower, though usually not so. even in fruit. Legume exserted from the calyx, ovoid to oblong, bilocular, several- to many-seeded. - Sect.Asciocalyx was differentiated from Sect. Onobrychium on account of its inflated calyces. Although in the latter section the calyces are usually not inflated, there is a tendency in a few species to become slightly so (as in A. canescens and A. psoraloides). Since A. asciocalyx and A. melitenensis, the two Turkish members of Sect. Asciocalyx, closely resemble some members of Sect. Onobrychium in all but the inflated calyx, we have reduced the former section to synonymy. Sect. Onobrychium is closely related to Sect. Ornithopodium and can only be distinguished with certainty from the latter by its shorter legumes, less than 15 mm.
