A. dioica (L.) Gaertner, Fruct. et Sem. 2, 410, t. 167 (1791). Syn: Gnaphalium dioicum L., Sp. PL 850 (1753). Ic: Hegi, I11. Fl. Mittel-Eur. 6(1): t. 261 f. 2 & 2a (1917).   Leaves of basal rosettes and prostrate sterile shoots obovate-spathulate, 1∙5-2∙5 x 0∙3-0∙8 cm, attenuate at base, obtuse or retuse, mucronate at apex, entire, covered on both surfaces with silvery tomentum but more densely so beneath. Peduncles 3-15 cm, erect, bearing narrowly oblanceolate, acute or acuminate leaves up to 3 mm broad. Capitula 5-6 mm broad, 3-6 per corymb. Outer phyllaries lanate, inner ones white to pinkish-scarious, those of female capitula linear-lanceolate, c. 1 mm broad, those of functionally male capitula obovate, obtuse or subacute, 2-2∙5 mm broad. Female corollas 5∙5-7∙5 mm, functionally male corollas 4∙5 mm. Fertile achenes c. 1 mm. Pappus white, ± as long as flowers, deciduous. Fl. 6-7. On steep slopes and upland pastures sometimes amongst Pinus sylvestris, 2000-2300 m.   Described from Europe (Hb. Cliff. 400/1!).   N.E. Anatolia.

(Palandöken Da.), Huet.   Europe, N. Asia. Euro-Sib, element. This widespread subapomictic species has been divided into several varieties of which the Turkish specimens are probably closest to var. australis Gris. (Spic. 2:198, 1845) in that its leaves are persistently tomentose on both surfaces. Certainly, none of the Turkish material examined matches the larger size of A. caucasica Boriss. (Not. Syst. (Leningrad) 20:289, 1960) which, it has been suggested, may be native in N.E. Anatolia.
