Description:
Perennial. Root long, too low branched, penetrating deep into the stony or scree terrain. Stems at 1 - 3, 30 - 50 cm tall, 1.5 - 3 mm diameter in the basal part, at least twice thin at the top, unbranched, solid in consistency and pale green on the surface, most often for the most part light purple and the entire surface smooth. Leaves 5 - 6 to numerous, but mainly at the base of the stems forming a kind of rosette, mostly shovel-like;Upper stem leaves almost linear or ovate lanceolate back, no sharp boundary between the lamina and the stem with respect to length 1:1; total length of 5 - 10 cm and a width of 1 - 2 cm with a smooth edge with rare or indentations; leaf blade fleshy, colored gray-greenish and stems almost always tinted light purple. Blossoms in elongated cluster at the top of the stem, 8 - 10 mm long, with thin, equal to their stems. Sepals 4 - 5 mm long, yellow-green. Pale yellow petals, 8 – 10 mm long, in its upper part from 2.5 to 3 mm in clear width; Nails 2/3 to 4 / b of the length of the rolled sheet of dough; stamens 6 - 8.5 mm long, anthers means 2 - 2.5 мм long, the pedicle about 1 mm long. Pods 20 - 40 mm long and 1.5 - 2.5 mm in clear width, covers with a highly convex longitudinal streak; ginof 1.5 - 3 mm long; prow 1 - 1.5 mm long, kidney-shaped tip thickened.

Brassica jordanoffii O.E. Schulz
Brassicaceae – Cabbage family
Conservation status. Vulnerable [VU B1ab(iii); C2a(i)]. BDA. Bulgarian endemic.
Morphology and biology. Perennial herb. Flowering stems 30–50 cm. Leaves glabrous, somewhat fleshy, basal spathulate, cauline oblong-lanceolate. Flowers pale yellow arranged in a terminal racemose inflorescence. Fruit 20–40 mm long siliqua, shortly beaked. Fl. VII–VIII, fr. VIII–IX. Insect pollination. Reproduction by seeds.
Habitats and populations. Grows in stony and rocky places on limestone in the subalpine vegetation belt, sometimes also at the timberline of the coniferous forests, on shallow or poorly developed soils. Takes part in hasmophytic communities together with Alyssum trichostachyum, Armeria alpina, Dianthus microlepis, Saxifraga ferdinandi-coburgi, and Arabis ferdinandi-coburgi. Population is fragmented but fragments are with good numerical strength, usually of more than 600–800 individuals, and good reproductive potential.
Distribution in Bulgaria. Pirin Mts (northern – above Bunderitsa chalet, Dzhamdzhievi Skali locality, slopes of Kutelo peak, Golyam and Malak Kazan, Banski Suhodol, Razlozhki Suhodol cirques, around Suhoto Ezero); from (1850)2100 up to 2500 m alt.
General distribution. Bulgaria.
Threats. The intensive tourism and trampling outside the tourist trails cause habitat destruction and reduction of the population size. Potential threats are natural disasters (land slides, fires, avalanches).
Conservation measures taken. Protected species according to the national Biodiversity Act (listed as B. nivalis subsp. jordanoffii). The localities are within Pirin National Park and Bayuvi Dupki - Dzhindzhiritsa Strict Nature Reserve as well as in a site of the European ecological network Natura 2000 in Bulgaria.
Conservation measures needed. Restriction of tourists hiking within the tourist trails only; deposition of seeds to the National Seed Genebank in Bulgaria; research into the possibilities for ex situ cultivation of the species.
