(c) Subsp. petraea (Ten.) R. Fernandes, Bot. Jour. Linn. Soc. 70: 7 (1975)

( A. petraea Ten. ):

Stems usually 16-35 cm. Leaves up to 5 x 2 cm, somewhat thicker and more densely glandular-punctate than in subspp. (a) and (b); peduncles 7-25 cm; involucre somewhat umbonate; ligules up to 12(—16) x 5(-7) mm. Disc 8-13 mm in diameter. Achenes 2-5-3 mm, rather attenuate to the base, with a distinct, hyaline oblique corona c. 0- 5 mm. • C. Appennini, IE. Pyrenees.

Some plants from Albania, Greece and Bulgaria which have been referred to A. orientalis var. macedonia (Griseb.) Hayek are like sericeous variants of subsp. (a), but have more numerous and crowded stems, less hairy leaves, an umbonate and more convex involucre, with sometimes almost obtuse bracts with a less distinct black margin; the receptacle is usually conical and acute and the scales less distinctly 3-dentate. They approach 19(b) but differ from it in several characters and may prove to be a distinct species.

Plants from Austria (Steiermark), sometimes known as A. styriaca Vest , Syll. Pl. Nov. Ratisbon. (Königl. Baier. Bot. Ges.) 1: 12 (1824), have stout stems usually 11-16 cm, wide leaf-lobes and large capitula with wide ligules. They may, perhaps, represent another subspecies, but similar variants occur sporadically elsewhere.

Plants from the E. Pyrenees, sometimes referred to 2(c), are somewhat intermediate between this and sericeous variants of 2(a).
