E. absinthoides Willd., Sp. PL 3: 627 (1800). Dioecious perennial, usually with few lax rosettes. Basal leaves l-2(-3)-pinna-tisect, blade ovate to narrowly oblong, 2-13 cm, primary segments varying from shortly pinnatifid to deeply 2-pinnatisect, adpressed-pilose, canescent or sub-sericeous, usually eglandular. Stems simple or sparsely branched, prostrate or ascending, hirsute or canescent. Sepals 4.5-7 mm in flower, usually pilose and glandular-pubescent; awn 0.2-2.8 mm. Petals obovate, 1-2½ x sepals, white, pink or lavender-blue. Beak of fruit 4-7 cm, stout. A very variable species, to which several of its allies should perhaps be subordinated. Four subspecies are recognised here; another (subsp. elatum (Form.) Davis & Roberts) grows in N. Greece. 1. Lamina of basal leaves oblong, length 2-4 x width, segments laxly and deeply 2-pinnatifid into lanceolate acute laciniae; stems bearing 1-12 peduncles 2. Leaves densely canescent; stems grey with short, retrorsely adpressed hairs; flowers white subsp. absinthoides 2. Leaves greenish, adpressed-pilose; stems patently hirsute, often also bearing subsessile glands; flowers lavender-blue . subsp. armenum 1. Lamina of basal leaves ovate, length c. 1.5 x width, segments 1-2-pinnatifid into short obtuse laciniae or teeth; stems bearing 1-2 peduncles 3. Segments deeply pinnatifid, subsericeous; flowers bright pink subsp. latifolium 3. Segments lobed only to the middle, greenish; flowers white subsp. haradjianii subsp. armenum (Trautv.)
