enclosed in a hairy involucre, formed by a series of narrow 

 green bracts, grow singly or in pairs at the ends of the long 

 slender stalks. 



A. CIiamisso7iis, or Chamisso's Arnica, is an extremely 

 hairy species, usually found near water. The leaves are very 

 long and narrow, and slightly toothed ; the flowers are smaller 

 than those of the Heart-leaf Arnica, and grow in clusters. 



A. alpina, or Alpine Arnica, is a graceful delicately formed 

 plant, with long, narrow, toothed leaves, and a single flower 

 terminating each stem. It also frequently has two additional 

 flowers springing from the axils of the upper leaves. Several 

 pairs of leaves grow on the stems, and altogether the plant 

 presents a more slender, refined appearance than do either 

 of the two preceding species. 



A. Parryi, or Parry's Arnica, bears a curious flower with 

 no rays at all, but only a receptacle of disk-flowers enclosed 

 in a green involucre. These flower-heads usually grow in threes 

 at the summit of the three short -branched stems. They appear 

 to have simply lost their rays in the early stage of decompo- 

 sition, but such is not the case ; they never had any.

 axils of the lower leaves. Leaves : basal ones slender-petioled, oblong,

 corymbose many-flowered beads of both tubular and ray-flowers. 



This is a very common plant in the mountains. It has 

 bright yellow flowers, which when in seed resemble small 

 thistles. The rich loose clusters of the Golden Ragwort 

 grow to an average height of eighteen inches. The basal 

 leaves have long stalks and are rounded or oblong, with scal- 

 loped edges, while the stem-leaves are long, narrow, and slen-
