Perennial plant making dense tufts. Stems of the blossoms are rising slightly, 10 - 20 cm high, covered with curly hairs. Lower leaves with handles, above sessile, linear or lanceolate to elliptic lanceolate, usually up to3 mm wide, with tufts of leaves in their bosom. Lowest leaves without such bundles in their bosom. Leaf lamina of all the leaves on both sides straticulate, gray or white, or covered with thin curly and tangled hairs, on top with visible yellowish over, the back with a sharp ridge. Dichotomous branched inflorescence, with many blossoms. Blossom handles 2 - 3 times longer than the calyx. Blossom petals lanceolate, sharp, on the edge with a wide webbed edge. Sepals lanceolate, acute, 6 - 8 mm in length, fibrous, often with glandular hairs, much shorter than the petals. Petals white, outstretched, naked. 5 bars. Fruit box wide cylindrical, with 10 straight teeth with rolled edges. Seeds from 1.5 to 1.7 mm in length, highly pimpled with low conical warts. Volatility

Distribution: Mountains of the Balkan Peninsula – the Dinarides and the Hellenides in all states of the former Yugoslavia, mountains of Albania, Bulgaria and Greece (incl. some of the East Eagean Islands). It grows in grasslands on rocky slopes, pine forests, in extensively grazed pastures and similar habitats. On calcareous soils (on limestones, dolomites, serpentinits), in 1000–2000(–2500) a. s. l.
Description: A perennial herb, 7 - 40 cm high, at least in inflorescense and on leaf margins with long, soft hairs. The leaves usually 3 - 5 mm wide, at least 3× longer than wide, lanceolate to elliptic-lanceolate, acute, tomentose to pubescent or glandular. The flowers in cyme, bracts and sepals lanceolate, acute, with wide scarious margins, sepals 6 - 8 mm long, pubescent, often glandular. The capsule 7 - 9 mm, broadly cylindrical, teeth erect, with revolute margins. The seeds 1 - 1,3 mm, strongly tuberculate.
Note: This species is very variable, mostly in type of trichomes, many varieties and forms have been described. Seven subspecies are accepted: subsp. adamovicii (Velen.) Stoj. et Stef., subsp. dollineri (Beck) Gajic ex Greuter et Burdet, subsp. durmitoreum (Rohlena) Gajic, subsp. histrio (Correns ex Prain) Greuter et Burdet, subsp. macedonicum (Georgiev) Stoj. et Stef., subsp. orbelicum (Velen.)
