Composites and Scabious. 



Family of the Composiiae and of the Di- 

 psaceae. 



Fig. 1. Arnica. Easily known from all 

 other yellow Composites by the sessile lea- 

 ves of the stem being in pairs fopposite). 



l'ejity moors, dry meadows, heathy soll, 

 beds of moiüd, heaths, from the moun- 

 tain region up to 2800 m. 



Fig. 2. Alpine Starwort. Could only be 

 confounded with the Alpine Erigeron (Eri- 

 y:eron alpinus), the latter possesses however 

 very narrow ray-flowerets placed in se- 

 veral rows. 



Meadows, rocks, beds of mould, from 

 about 1400-3100 m., also lower. 



Fig. 3. Edelweiss. Easily known by its 

 white hairy clothlike heads. That which 

 looks like a large flower at the end of the 

 stalk is in reality a very composite struc- 

 ture. It consists of numerous many-flowered 

 heads. whose white, wooily, radialy arran- 

 ged braets Imitate a flower, in order to at- 

 tract insects to the inconspicuousrealflowers. 



Rieh meadows, belts of turf, on rocky 

 slopes, espec. on chalk, from 1900—2900 m. 



Fig. 4. Wooily Hawkweed. Known by its 

 long whitish, thickly placed hairs which 

 envelope the whole plant with a kind of 

 für. The outer leaves of the involucre 

 stand off. 



Beds of mould, belts of turf, rocks, 

 from 1100—2800 m. 



Fig. 5. Skorpion-Wort. Possesses tongue- 

 shaped marginal and tubeshaped central 

 flowerets, a henäspherical involucre, alter- 

 nate leaves (difference from Arnica) and 

 broad heartshaped rootleaves. 



Stony debris, espec. on chalk, from 

 14(0 -2800 m. 



Fig. 6. Golden Hawk's-beard. Easily 

 distinguished from all other Alpine Com- 

 posites possessing naked and one-headed 

 stems by the deep orange tint of its flowers. 



Meadow plant (excellent herbage for 

 fodder), from 1000—2900 m. 



Fig. 7. Musk Milfoii. Leaves strongly 

 aromatie, especially if rubbed, with dots 

 and with undivided and unidented segments. 



Alpine pastures, turfs, debris, rocks, 

 from 1600-3400 m. Especially on primary 

 formations. 



Fig. 8. Lucid Scabious. Is not a Com- 

 posite, but belongs to the nearly allied fa- 

 mily of the Teasleworts (Dipsaeeae), in 

 which the Anthers are separated instead of 

 being eoalesced to a tube. Eaeh flower pos- 

 sesses 4 far protruding stamens and an un- 

 divided style. 



Meadows, Strips of turf, from about 

 1800—2680 m. 



Fig. 9. Black Milfoii. Distinguished 

 from the nearly allied Musk Milfoii (fig. 7) 

 by its more strongly divided leaves which 

 are not aromatie and not dotted. 



Rocky debris, Alluvium of streams,
