 Alpine Shrubs. 



Fig. 1. Crowberry. A small low shrub growing 

 in tufts with dark-coloured leaves, which on 

 account of being rolled back at the margins 

 appear needleshaped. The flowers are very 

 small. The fruit is a blackish berry. 



On heaths, peatbogs from about 1000 to 

 2700 m. 



Fig. 2. Common Heath. Easily known by 

 its short needleshaped leaves and by its small 

 pink flowers which do not open till late in the 

 year. Always on poor soil, from the sea- 

 level up to 2300 m ; on heaths, dry peatmoors, 

 poor Alpine meadows. 



Fig. 3. Mediterranean. Leaves needleshaped 

 calyx and corolla red; stamens protruding, 

 brown. 



Widely spread, a chalk loving rock plaut 

 ascends up to 2700 m. 



Fig. 4. Alpine Bearberry. The recumbent 

 stems are covered with deciduous leaves which 

 are finely serrated at the margin turning red 

 in Autumn. 



Rocky terraces, shallow-soiled meadows, 

 slopes of debris; from about 18002640 m. 



Fig. 5. Common Bearberry. Leaves thick 

 and leathery, on the upper side of a glossy 

 green, without brown glands on the under side 

 (distinction from Cowberry). 



Sunny slopes espec. on chalk, up to 2760 m. 



Fig. 6. Bilberry or Whortleberry. Stem with 

 sharp edges, the pointed leaves finely serrated 

 on the margin, deciduous; flowers single. Berries 

 bluish black (rarely white). In woods from 

 the plains up to the tree-limit and even higher, 

 on poor meadows up to 2600 m or more. 



Fig. 7. Bog Bilberry or Whortleberry. Nearly 

 allied to the Bilberry, but differing from it in 

 its round (not angular) stem, in its leaves which 

 are bluish green on the under side, in its clusters 

 of flowers and in the insipid taste of its berries. 



Moors, aretes, from 8003000 m, also des- 

 cending lower. 



Fig. 8. Cowberry Red Whortleberry. The 

 leaves are evergreen and are rolled back at the 

 margins, on the under side they are dotted with 

 small brown glands. In mountainous woods and 

 open cattle-ranges, etc. up to about 2200 m. 



Fig. 9. Hairy Alpine Rose. Low, thickly 

 branching shrubs with short twigs; leaves round 

 or elliptical, thin, and of a bright green, fringed 

 on the margin with long hairs; on the under 

 side (more rarely also on the upper one) are 

 scattered brown scales; the corolla is rather 

 more lightly coloured and opens earlier than that 

 of No. 10. 



Rock plant, preferring chalk, from 1400 to 

 2500m. 



Fig. 10. Rusty -leaved Alpine Rose Shrub 

 higher and less branching but with longer 

 twigs; the daik green, elliptical or long-lan- 

 cetshaped leaves rolled back at the margin ainl 

 without hairs, thickly covered with scales on 

 the under side, turning rusty brown. 



Growing on peat especially on the primary 

 formations, 13002500 m (in ficino often lower 

 down). 



Fig. 11. Creeping Azalea. Leaves thick and 

 leathery, rolled back at the margin. A small 

 creeping shrub forming clumps. 



Espec. on aretes, elevated Plateaux, often 

 covering boulders with intertwined masses, from 

 18003000 m (rare at 1400 m).
