Fig. 1. Basil-leaved Soapwort. Belongs to 

 the pinks; calyx undivided, red, with a glan- 

 diferous tube. A rockplant growing on sunny 

 places from the lakes of the lower Alpine region 

 and from the vineyards of the bill region up t* 

 2400 m. 



Fig. 2. Northern Linnaea. Creeps with it* 

 threadlike stems among the moss of the Alpine 

 woods, especially in the zone of the larches and 

 Swiss stone-pines. It does not ascend into the 

 real Alpine region. It is found scattered 

 throughout the central chain. 



Fig. 3. Alpine Butterwort. The leaves are 

 rolled inwards, they are covered with numerous 

 glands which serve to catch insects and to digest 

 and absorb them. 



Swamps, wet rocks, from the mountain 

 region up to 2600 m. 



Fig. 4. Common Butterwort Easily dis- 

 tinguished from the preceding species by its 

 violet flowers : Swampy meadows from the plains 

 up to 2400 m. 



Fig. 5. Grass of Parnassus. It is at once 

 known by its sessile heartshaped stem leaf.
