The plant is 3-15 cm high, almost woody at base, with branches finished in rosettes of leaves. The strain is unfolied or very rarely with 1-2 twigs without leaves. The leaves are oblong, attenuated to base, acute, entire or with 1-2 "teeth" at peak. Flowers are small, white. The fruit is elliptical, rounded at both ends, 4.5-6.7 mm long, 2-3 mm wide. The plant is near extincted, strictly protected (Council of Europe 1979) and grows in a small area (400 sqm!) in Retezat Mountains National Park.
