Papillonacees. 



Fig. 1. Tröfle des Alpes. Cette belle 

 espece de trefle est caracterisee par ses 

 feuilles h folioles dtroites, ses grands capi- 

 tules paiieitlores, partants de la souche, par 

 Tarome fin de ses fleurs et sa racine pivo- 

 tante tres developpee. 



Päturages, pres, gazons, de 1700 a 3000 

 m., surtout sur le terraiu primitif. 



Fig. 2. Treue brun. Fleurs d'abord 

 jaunes et dressees, puis bruues et recourböes 

 vers la terre. 



Päturages, eboulis, de 1500 a 2700 m. 



Fig. 3. Oxytropide des montagnes. Les 

 Oxytropides se distinguent de toutes les 

 autres Papillonacees par leur carene ter- 

 minee par une petite poiute. L'espece figurtie 

 ci-contre ditfere des autres Oxytropides al- 

 pines ä fleurs bleues par les dents courtes 

 de son calice et en ce que la plante n'est 

 pas revetue de poils soyeux. 



Päturages, rochers, eboulis, de 1500 k 

 3000 m. 



Fig. 4. Oxytropide des champs. Differe 

 d'une espece voisine (O. foetida) par l'ab- 

 sence de poils glanduleux sur les feuilles, 

 fleurs blanches, jaunätres, rarement d'un 

 bleu sale. 



Päturages, gazons, de 1700 ä 3000 m., 

 souvent deseendant dans la plaine. 



Fig. 5- Esparcette des Alpes. Caracte- 

 risee par sa grappe multiflore, composee de 

 fleurs pourpres et par sa gousse applatie se 

 divisant a la maturite en des segments ar- 

 rondis contenant chacun une graine. 



Gazons, vires, rarement sur les pätu- 

 rages, de 1700 ä 2800 m. 



Fig. 6. Phaca froide. Se distingue par 

 ses grands stipules d'un vert pale et par la 

 couleur blanchätre de ses fleurs.

Papilionaceous Plants. 



Papilionaceae. 



Fig. 1. Alpine Trefoil. Our most beauti- 

 ful and sweetest scented species. Easily 

 known by its narrow leaflets, its large ra- 

 dical heads, composed of but few flowers, 

 its sweet scent and its large and very tough 

 tap-root. 



Pastures, rieh meadows, turf, belts of 

 grass, beds of mould, from about 1700 

 to 3000 m. (rarely already at 1000 m.), more 

 especially on the primary rocks. 



Fig. 2. Brown Trefoil. The flowers are 

 at first upright and of a brilliaat yellow; 

 after blooining they hang down and become 

 brown. The corolla remains attached to 

 the fruit and acts an important part in the 

 distribution of the latter. 



Pastures, places destitute of grass, roeky 

 de bris, from 1500—3000 m. 



Fig. 3. Mountain Oxytropis. The moun- 

 tain Oxytropis can be distinguished from 

 all other Papilionaceae by a small deut 

 situated at the anterior end of the keel. It 

 difters froin all other blue flowered species 

 of the Alpine Flora by the short teeth of 

 the calyx and the absence of silky hairs. 



Pastures, belts of rock, slopes of debris, 

 „Wildheuplätze" (vide plate 4), from 1500 

 3000 m. 



Fig. 4. Yeliowish mountain Oxytropis. 

 We have only two yellow Oxytropis in our 

 Alps: the foetid oue (O. foetida ü. C.) with 

 sticky glauds and the present one, whose 

 leaves are glaudless. The flowers are white, 

 yeliowish white, or rarely of a dirty blue. 



Pastures, belts of grass, beds of 

 mould, from 1700 — 3000 m., often descending 

 in to the valley. 



Fig. 5. Alpine Saint-foin. This plant is 

 characterised by an abuudantly flowering 

 raceme of dark purple, usually hanging 

 flowers and by a flattened pod which di- 

 vides iuto roundish segments. 



„Wildheuplätze", belts of turf, beds 

 of mould, more rarely on pastures, from 

 1700—2800 m. (rarely already at 1300 m.). 



Fig. 6. Frigid mountain-lentil. ßecogui- 

 sed by the large light yellow stipules at 

 the base of the petiole and by its whitish 

 yellow flowers. 



„Wildheuplätze", belts of turf, beds 

 of mould, from 1700—2700 m. (rarely al- 

 ready at 1500 m.
