Abstract
Two apomictic species in Hieracium sect. Subalpina are described from Mt. Babia Góra in the Western Carpathians, southern Poland. Hieracium bronae belongs to the H. vagneri agg. and is distinguished by the sharply dentate leaves. Hieracium rohacsensiforme differs from H. rohacsense in smaller capitula, the shape of the leaves, which are almost devoid of glandular hairs on the margins, and yellow styles. Both new species are illustrated with photographs of their holotypes.
