Determined according to the botanical key provided in Flora Europaea Vol. 5 (Tutin et al., 1980).
Lifeform: Perrenial; Hemicryptophyte according to the Raunkiær system.
Distribution: Balkan peninsula. According to the Euro+Med Plantbase (Marhold, 2011) it is found in Bulgaria, Greece, North Macedonia and Serbia.
Habitat: Dry and somewhat shaded positions on rocky substrate- river gorges, rocks and cliffs shaded by the surrounding dendroflora, among moss and lichens.
Description: A caespitose evergreen perennial up to 10 (-15) cm high at anthesis, forming lax mats of up to 10 -15 cm in diameter. Stems numerous, simple (sometimes branched), develop from an underground tuberous rhizome. Tubers oblong, brownish, covered with scales. Flowering stems up to 10 to 15 cm long including the inflorescence, procumbent to erect. Sterile basal rosettes comparatively shorter, present at flowering (may develop at any time). Cauline leaves numerous, alternately arranged, almost linear in shape, slightly wider in the distal half (linear-oblancelate), obtuse with entire margin, 6 to 8 mm long x 1.1 to 1.4 mm wide, flattened, 0.6-0.8 mm thick. Basal leaves (leaves of non-flowering rosettes) shorted and wider, almost spathulate, densely arranged. Inflorescence a lax cyme. Flowers 5-merous: sepals, petals and carpels 5, stamens 10. Petals bright yellow, lanceolate, 2 to 2,5 times as long as calyx. Carpels erect, fruiting follicles patent.
Flowering period: Late spring to early summer: JUN.
