subsp. bashkalense Davis & Parris in Notes R.B.G. Edinb. 33:414 (1975).
Many-stemmed perennial, 100-150 cm. Stems branched, unwinged, glabrescent or sparsely arachnoid. Median cauline leaves oblong, pinnatisect, lateral lobes unequally bifid, c. 4-5-paired, triangular to long-triangular, lateral and terminal lobes with 4-10 mm apical spine, sparsely spinose-strigose above, setae c. 5 per 2 mm square, 0.2-2.2 mm, otherwise glabrous or very sparsely arachnoid; glabrous below or very sparsely arachnoid. Lateral branches short, c. 5-11, with many-capitulate racemes or racemose panicles, uppermost leaves 2-4, usually shorter than involucre, rarely equal to or longer than it, involucrate. Involucres erect, obconical-cylindrical to obconical-obovoid, 10-15 mm. Phyllaries arach-noid, c. 8-seriate; median 7-12 mm incl. ± erect to reflexed 0.5-1.3 x 0.1-0.15 mmapical spine.

Endemic? Differs from subsp. oduncum (Caucasus, Transcaucasia, N.W. Iran, N. Iraq) in having involucres with obconical rather than rounded base. However, an illustration in Fl. URS S (28: t. 5 f. 1, 1963) closely matches subsp. bashkalense in involucre shape.
