COMPOSITE 173 



Doronicum Clusii Tausch (Aronicum Doronicum Jacq.). 



Stem about a foot high, hollow, covered with rough hairs like 

 the leaves, simple, leafy. Leaves lanceolate ;j root-leaves often 

 ovate, entire, or coarsely dentate, or with a wavy margin ; lower 

 stem-leaves stalked, upper ones sessile, with a narrowed or rarely a 

 rounded base. Capitulum solitary, large, and handsome, bright 

 yellow. 



Among boulders and on stony pastures and on debris of the Alps 

 (avoiding limestone) ; 5000-7600 feet. July, August. 



More strictly Alpine, a description of this species is given because 

 it is often confused with other plants, and by novices even with 

 Arnica. 



Distribution. Carpathians, Eastern, Central, and Western Alps, 

 Spanish Pyrenees. Not in the Jura. 



ARNICA L. 

 Arnica montana L. (Plate XX.) 



Stem erect, i-i J feet high, glandular villous, bearing 1-3 capitula, 

 and i or 2 pairs of small leaves, naked above. Leaves entire, oval- 

 lanceolate or oblong-lanceolate, glabrescent, narrowed into a short 

 foot-stalk, and forming a rosette ; stem-leaves opposite, lanceolate, 

 sessile, much smaller. Flowers bright orange-yellow. Capitula 

 2-2J inches in diameter, though frequently not perfect. A well- 

 known, bitter, medicinal plant. 



Alpine and sub- Alpine pastures and clearings in woods ; 3400- 

 8000 feet. Especially on granitic or siliceous soil, where it is some- 

 times very numerous. June to August. 



Distribution. Carpathians, Eastern, Central, and Western Alps, 

 Erzgebirge, Black Forest, Vosges, rare in the Jura, Cevennes, 

 Pyrenees, and the greater part of Europe as far north as Sweden, 

 N. Asia. 



Easily grown in deep soil a mixture of loam and peat or leaf- 

 mould is best. Increased by seed or by division. 



SENECIO L. 



Leaves alternate, toothed or divided, rarely entire. Flower-heads 

 in terminal corymbs. Disk-florets yellow, and tubular ray-florets 

 yellow, blue, purple, or white, spreading. Involucre cylindrical 

 or nearly hemispherical, with i or 2 rows of linear bracts, often 

 tipped with brown. Receptacle without scales. Achenes cylin- 

 drical, with a pappus of simple hairs, usually soft and white. 



One of the largest genera, if not the largest, in existence, and 

 spread over the whole globe, though most of the species are con- 

 fined to a small area only. Several species which have not * the 

 small outer bracts to the involucre were distinguished by Linnaeus
