Subsp. bansagensis (H. Wagner) Soó, Syn. Syst. Geobot. Fl. Veg. Hung. 4: 174 (1970) (C. bansagensis H. Wagner), from Romania, is like 189(b) but has the leaves densely arachnoid-lanate, the middle cauline leaves lanceolate or elliptical, the involucre 14-18 x 12-14 mm and brown, recurved appendages; subsp. joannis Kárpáti , Borbásia 5-6: 92 (1946), described from N.W. Jugoslavia, is like 189(c) but has the leaves wider and shorter, the lower leaves green and the upper mostly lanate, clustered capitula and the involucre c. 10 x 3-4 mm; the status of both these taxa is uncertain.
