D. bruniifolia Stev. in Mem. Soc. Nat. Mosc, 3: 268 (1812).
Cushion or mat-forming perennial. Scapes l-8(-10) cm, densely villous to glabrous. Leaves linear, rigid, with pectinate-ciliate margins, and the surface glabrous, or with an indumentum of simple or small stellate hairs. Petals bright yellow. Ovary with 4-10 ovules. Siliculae ovoid, 3.5-6 x 2.5-3.5 mm, hairy. Style 0.3-0.75 mm. Fl. 3-7. A very polymorphic species, which may be further divided:
1. Scape glabrous
2. Fruit indumentum of long, simple hairs
   3. Inflorescence 3-8-flowered, conferted in fruit subsp. archipelagi
   3. Inflorescence 7-many-flowered, elongate in fruit subsp. heterocoma
   3a. Leaves with hairs on the margin only, all simple var. heterocoma
   3a. Leaves with hairs on the lamina as well as on the margin, some branched var. nana
2. Fruit with an indumentum of short, crisped hairs subsp. kurdica
1. Scape villose
    4. Leaves with simple hairs on the margin only; inflorescence contracted, 3-8-flowered subsp. olympica
    4. Leaves with hairs on the lamina as well as on the margin, often many-branched; inflorescence lax, 7-many-flowered
     5. Fruit with an indumentum of simple and branched hairs; leaves 8-10 mm subsp. bruniifolia
     5. Fruit with an indumentum of simple hairs only; leaves 11-12 mm subsp. armeniaca

Transcaucasia? Iran? It is possible that D. globifera (described from Ararat) is synonymous with this subspecies rather than with subsp. bruniifolia; we have seen only a photograph of the type, and it is not possible to see the details of the indumentum necessary for distinguishing between these two taxa. From its description, Schulz's prol. buhsei (Iran) is very similar to subsp. kurdica; we have seen no authentic specimens of the former taxon.
