( A. mutellina Vili. , non S. G. Gmelin, A. laxa Fritsch ).

Caespitose, whitish-sericeous, aromatic perennial up to 25 cm. Leaves petiolate, palmately divided, the segments twice 3-fid (simple in the uppermost leaves); lobes linear, subacute. Capitula 3-5 mm across, ovoid, more or less erect, the lower pedunculate, distant,

the upper nearly sessile in a usually simple, rather lax raceme; lower bracts like the cauline leaves, the upper mostly simple. Involucral bracts villous-sericeous, oblong-lanceolate, obtuse, the outer with a scarious, the inner with a brown margin. Receptacle shortly and sometimes sparsely hairy. Florets 10-20, the female more numerous than the hermaphrodite; corolla yellowish, the lobes slightly hairy. Achenes with sessile glands and some hairs. 2/7 = 34. Mountain rocks, moraines and river-gravels. • Alps, N. Appennini. Au Ga Ge He?Hs It.

A. gabriellae Br.-Bl. , Trav. Soc. Pharm. Montpellier 4: 233 (1945), from the E. Pyrenees, is like 34 but has a more dense, silvery indumentum, leaves with wider and more obtuse segments, capitula fewer and more crowded in a terminal corymb, and glabrous achenes. It has 2/7 = 34 and is perhaps best regarded as a subspecies of 34.

The identity of plants from the C. Pyrenees and Sierra Nevada which have been referred to 34, is uncertain.
