(inch D.sanguineus Vis. , D. rogowiczii Kleopow ).

Glabrous perennial up to c. 60 cm. Leaves 0-5-5 mm wide, linear, acuminate, flat; sheaths several times as long as diameter of stem. Flowers few to many in a usually dense head; bracts lanceolate to oblong, more or less herbaceous to coriaceous. Epicalyx-scales obovate to obcordate, abruptly aristate, coriaceous to membranous. Calyx 10-20 x 2-5 mm, narrowed above the middle. Petal-limb usually 10- 15 mm, dentate, deep pink to purple, very rarely white, bearded. 2n = 30. • S., W. & C. Europe. Al Au Be Cz Ga Ge He Ho Hs Hu It Ju Po Rm Rs (W) Si Tu. A very variable species whichhas been much subdivided. The variation in leaf-width, length of awn, colour, shape and texture of epicalyx-scales, length and colour ofthe calyx, and petal-size seems to be largely continuous and with little correlation between the different characters. The variation does not in general fall into a geographical pattern, though some fairly distinct populations appear to exist, especially near the limits of the distribution of the species. For diverse accounts of the intraspecific taxa see Ascherson 6 Graebner, Syn. Mitteleur. FI. 5 (2): 306-30 (1921), Hegi, III. FI. Mitteleur. 3: 323-6 (1910), and Prodan in Sävul. FI. Rep. Pop. Romane 2: 250-5 (1953).

D. commutatus (Zapal.) Klokov in Kotov, FI. RSS Ucr. 4: 659 (1952), is very robust with wide leaves and a puberulent calyx, but otherwise resembles 108.
