Stem 2-3 feet high, erect, terete, leafy. Leaves pinnatifid, large, deeply and much divided; the lower leaves ovate-triangular in outline, pinnatipartite, with 3-7 segments, the inferior segments being distinct, the upper confluent, sharply toothed; uppermost leaves narrow, lanceolate, not divided, but sharply toothed. Corymbs very compound. Flowers white, small.
Woods and shady places in the Alps and sub-Alps; 3000-6800 feet.
Eastern, Central, and Western Alps; local.
A useful subject for planting in the shade of trees at the back of a rockery, for the foliage is rather handsome.
Capitula solitary, often large. Ray-florets ligulate, white or yellow; disk-florets tubular, perfect, yellow. Receptacle flat or convex, naked. Involucral bracts imbricate, with scarious margins. Fruit of ray-flowers ribbed or winged, of disk-flowers compressed. Leaves toothed or cut. A genus sometimes divided into several small genera.
Stems erect, simple, or slightly branched above. Root-leaves obovate and coarsely toothed, on long stalks; stem-leaves narrow, sessile, with fewer teeth. Flower-heads solitary, very large, especially in the Alps, on long, terminal peduncles. Involucral bracts bordered with a brown, scaly edge.
Pastures, banks, and mountain slopes from the plains up to 7000 and rarely 8000 feet. June to August.
Europe, Russian Asia. Britain.
The figure depicts a rather small-flowered specimen. Stem 2-6 inches high, with a single capitulum. Leaves mostly radical, stalked, spathulate, pinnatifid, with 5-7 segments, toothed, the uppermost linear, entire. Flower-heads about 1 1/2 inch across, white, disk yellow.

4/7 NATURAL SIZE.
Pastures and debris on the Alps, particularly on siliceous rocks. July, August; 5000-12,000 feet.
Carpathians, Eastern, Central, and Western Alps, Pyrenees, Transylvania.
Easily grown in a well-drained, southerly position, in a compost of sand and loam. It should be top-dressed each spring.
Root-leaves stalked or o; stem-leaves amplexicaul. Capitula solitary or in corymbs, rayed. Ray-flowers ligulate, usually female; disk-flowers with free branches of style; receptacle conicle. Fruit furrowed. Pappus-hairs rigid.
The nomenclature of the Alpine species of Doronicum (or Aroni-cum) appears much confused.
Root-stock often woolly at the crown. Root-leaves broadly ovate and deeply cordate at the base. Stem about 2 feet high, with few ovate-lanceolate leaves, the lower ones broader, stalked and embracing the stem in a broadly dilated base. Flower-heads 2-5 on long peduncles; handsome. Yellow ray-lfrorets numerous and narrow.
Woods and mountain pastures. May, June.
Rare in Switzerland. Jura, Vosges, Cevennes, Pyrenees, Central and Northern France, Spain, Italy, Central Europe. British.
