(e) Subsp. politus (Fries) H. Lindb. fil. View in CoL , Enum. Pl. Fennoscand. Or. 56 (1901)
( E. elongatus Ledeb. , non Moench):
Leaves glabrous, usually shiny. Involucral bracts with a few eglandular hairs at the base, purplish. 2л = 18. Fennoscandia and U.S.S.R., southwards to N. Ukraine.
Plants from the C. Alps have a weak, ascending habit quite unlike the normal erect habit; their status is uncertain. Two other subspecies have been reported from Finland and N. Russia: subsp. brachypetalus (H. Lindb. fil.) Hiitonen , Ann. Bot. Fenn. 8: 78 (1971), with small white capitula, and subsp. decoloratus (H. Lindb. fil.) Hiitonen , op. cit. T1 (1971), with white ligules. Both require further study.
There are scattered records, chiefly from N.C. Europe, of the sterile hybrid with Conyza canadensis ( E. huelsenii Vatke ).
