Hieracium decipientiforme (the H. nigrescens group) - an interesting species of the Ukrainian Carpathians

Hieracium decipientiforme (Woloszczak et Zahn) Šljakov, most probably an endemic taxon of the Ukrainian Carpathians, was found to be agamospermous tetraploid (2n=36). It occurs in mountain meadows, open places in krummholz stands and in subalpine grasslands in altitudes 1580-1900 m a.s.l. in the Gorgany Mts, the Čornohora Mts and the Marmaros Mts. Important distinguishing characters and relations to other related species groups are briefly discussed.
