Basal leaves 2-3-pinnatisect, 8-15 cm (incl. 2.5-6 cm petioles), oblanceolate in outline, primary segments (6-) 10-25-paired, generally opposite, c. 1-2 cm, secondary segments 2-10-paired, oblong-obovate, 1-4 x 0.4-1 mm, obtuse, subacute or acute at apex, margins entire or again divided into 3-5 lobes, greyish-pubescent and glandular-pitted; cauline leaves similar, 5-7 on each stem, becoming smaller and sessile above, uppermost ones often 1-pinnati-sect.

Type: Turkey B9 Van: 24 km from Gurpınar (Havasor) to Hoşap, 2000 m, Davis 44703!
S.E. Anatolia. B9 Van: d. Başkale, Ispiriz Da., 3200m, D. 23771! B10 Van: Özalp to Saray, 2250 m, D. 44295! Ağri: 3 km E. of Doğubayazit, 1750 m, D. 43914! N.W. Iran. This variety has been confused with T. uniflorum, a taller, more robust plant, the leaves of which have fewer and more distant primary segments and acute secondary ones (those of var. monocephalum are quite obtuse). The capitula of T. uniflorum are larger (c. 1 cm broad) and have longer ligules (0.75-1 cm).
