Fig. 1. Soldanelle des Alpes. Corolle 

 tres delicate et se detachant facilcMnent; 

 pour la conserver en herbier, ü fant mettre 

 sicher la plante dans im livre immediate 

 ment apres l'avoir deraeinee! La coi-olle 

 est campanulee, plus courte qae le pistil, 

 k limbe divisee profondement; tige por- 

 tant de 2 ä 4 fleurs. 



Comme la suivante, cette espeee annonce 

 le printenips des Alpes. Ces plantules de- 

 lieates fleurissent k cote de la neige fon- 

 dante; souvent, elles percent meme la 

 coiiche de neige et viennent au-dessus elever 

 triomphalement leurs corolles violettes. La 

 floraison se fait lors meine que la tempera- 

 ture de l'air ne depasse pas lO C. 



Tres repandue sur les päturages riches 

 en humus, dans des depressions humides, 

 de 1500 k 2400 m. (rarement dejk a 600 m.), 

 surtout sur le terrain calcaire. 



Fig. 2. Soldanelle delicate. Dilifere de 

 la precedente par ses feuilles plus petites, 

 sa corolle moins divisee, moins ouverte, et 

 plus longue que le pistil. 



De environs 1800 k 3000 m., plutot sur 

 le terrain primitif. 



Fig. 3. Ceraiste ä larges feuilles. Cinq 

 sepales et cinqpetales, 10 elamines; eajisule 

 allongee, en forme de corne, s'ouvrant au 

 sommet par des dents. 



Elle se trouve sur les eboulis, les mo- 

 raines et les eimes, de 2000 k 3500 m., en 

 compagnie de quelques especes voisines 

 tres semblables,

 cile k reconnaitre k sa rosette de feuilles 

 cotonneuses et k ses fleurs rouges de 9 k 12 

 petales. 



Endroits sees, rochers expos^s au soleil, 

 de 1700 k 1900 m. 



Fig. 5. Violette ä deux fleurs. Se dls- 

 tingue facilement des autres violettes jaunes 

 des Alpes par ses feuilles reniformes.

Plate 16. 



Fig. 1, Alpine Soldanella.. Belongs to 

 the family of the Primworts. The fragile 

 corolla falls very easily; it ought therefore 

 at once to be placed in a book! As far as 

 half way down it is prettily fringed and 

 Wide open like a funnei ; it is just as long 

 or shorter than the style; the stem with 2 

 to 4 flowers. 



Like No. 2 the first harbinger of the 

 Alpine Spring. These fragile pli. ts flower 

 close by the melting snow, ofteu even in 

 hollows under the snow at a temp'rature 

 of the air of at most lO C. (340 F.). They 

 offen melt a hole in the snow by their own 

 warmth and raise their heads triumpha tly 

 over their icy mantle. 



On all Alpine pastures, beds of mould, 

 snow-hollows, froni 1500—2700 m. (rarely at 

 600 m.), espec. ou chalk. 



Fig. 2. Delicate Soldanella. Differing 

 from the preeeding by its smaller leaves, 

 by its iess open and less deeply cut corolla, 

 which latter is longer than the style. 



Like the preeeding, from about 1800 to 

 3000 m., prefers the primary formations. 



Fig. 3. Broad-Ieaved Alpine Chickweed. 

 This plant is eharacterised by 5 separate 

 sepals and petals, 10 stamens, 5 separate 

 styles and a long horny seedvessel which 

 Springs open with teeth. 



With several other nearly allied and 

 with difficulty distinguished species this 

 plant inhabits the stony slopes, morains and 

 boulders of the high Alpine region, from 

 about 2000—3500 m., espec. on chalk. 



Fig. 4. Cob-webbed House-Ieek. This 

 House-leek can easily be known by its glo- 

 bular rosette of fleshy leaves and by its 

 purplish-red, many-rayed flowei's, whi3h 

 are overspun as if by a eob-web with loose 

 hairs. 



Di-y places, sunny roeks, from about 

 1700—2900 m. 



Fig. 5. Two-flowared Violet. Easily dis- 

 tinguished from the other yellow Alpine 

 Violets by its broad kidney-shaped leaves. 



Banks of brooks, shady damp fissures 

 in the rocks. Alpine woods, wet shingle, 

 from about lOüO— 3000 m. 



Fig. 6. Alpine Bartsia. A labiated flower 

 of the family of the Figworts, easily re- 

 cognised by the glossy violet of the topmost 

 foliageleaves. 



Pastures, belts of turf, beds of mould, 

 from 1500—2800 m. 



Fig. 7. Long-spured Violet. Leaves not- 

 ched, spur as long as the corolla. 



Pastures, beds of mould, boulder- 

 covered slopes, from 1800—3000 m. 



Fig. 8. White Dryas or Mountain Avens. 

 A dwarf shrub belonging to the family of 

 the Roseworts but with 8 petals; the leaf 

 is leathery, rolled back at the edge and 

 notched. The small fruits form with their 

 feathery styles a small grey brush. 



On pastures overgrowing the rocky 

 boulders with green carpets, on beds of 

 mould, aretes, slopes of debris, from about 

 1000—2900 m., in rocky places often descen- 

 ding lower.
