Gentianes. 



Les feuilles des Gentianes sont opposees 

 et sesslles, d'un goflt amer. Les fleurs a calico 

 4a5 divisions et a corolle tordue dans le 

 bourgeon possedent un long tube et un bord a 



4 ou 5 pointes. 



Toutes les Gentianes sont de mauvaises 

 herbcs. Dans le haut Nord se trouve settlement 

 No. 5, 9 et 10. 



Fig. 1. Gentian e printaniere. Plante vivace ; 

 a c6te des tiges fleuries on trouve des rosettes 

 de feuilles steriles. Les feuilles inferieures des 

 rosettes sont plus grandes quo les superieures. 

 (Caractere distinctif du No. 3.) Diffiere de 

 No. 2 par les feuilles plus pointues et les angles 

 ailes du calice. 



Pres marecageux de la plaine, paturages 

 des Alpes jusqu'a 3300 m. 



Fig. 2. Gentiane feuilles courtes. Feuilles 

 inferieures de la rosette plus grandes que les 

 superieures, ovales, brievement acuminees, angles 

 du calice non ailes. 



Pelouses, de 1900 a 3000 m. 



Fig. 3. Gentiane de Baviere. Feuilles in- 

 ferieures de la rosette radicale plus petites que 

 les superieures. 



Paturages, pelouses, eboulis, de 1800 & 3600m. 



Fig. 4. Gentiane utriculee. Espece an- 

 nuelle qui meurt aprfis la maturation de ses 

 graines sans laisser de rosettes de feuilles steriles. 

 Caracterisee par un calice renfle en utricule dont 

 les angles sont largement ailes. 



Pres marecageux, de la plaine j usque dans 

 les Alpes, mais pas trSs repandue. 



Fig. 5. Gentiane des neiges. Plante an- 

 nuelle, mais la gorge de la corolle non frangee, 

 angles du calice non ailes, limbe de la corolle 

 a cinq divisions. (Difference de No. 10!) 



Paturages, de 1800 a 2600 m. 



Fig. 6. Gentiane a tige courte. Sepales 

 lanceoles, devenant plus etroits des la base au 

 sommet, dresses; feuilles un peu coriaces, etroites 

 et pointues. Prefere le calcaire de 1200 a 2700 m. 



Fig. 7. Gentiane decoupee, Tres-voisine 

 de la precedente, niais sepales d'abord etroits 

 a la base puis plus larges, et recourbes en 

 debors; les feuilles sont moins coriaces, plus 

 larges et plus obtuses. 



Fig. 8. Gentiane d'Allemagne. Plante an- 

 nuelle; corolle a gorge frangee, d'un violet inipur. 

 Sur les pres de la plaine jusqu'a 2750 m. 



Fig. 9. Gentiane des champs. Se distingue 

 de la precedcute par le nombre des dents du 

 calice: canapestris en a 4, deux grandes et 

 deux petites (germanica en a le plus souvent 



5 d'egale grandeur; rarement seulement quatre). 

 La couleur de la corolle est egalement differente ; 

 elle tire da vantage sur le bleu dans campestris. 



Frequente dans les paturages alpins de 

 1500 a 27U) m. Plante alpestre plus que la 

 precedento. 



Fig. 10. Gentiane delicate. Plante annu- 

 elle. George de la corolle frangee; corolle 

 ordinairement a quatre divisions. 



Rare! Paturages, sables, eboulis, de 1900 a 

 2600 m. 



Fig. 11. Gentiane ciliee. Elle est facile a 

 distinguer de nos autres Gentianes par les 

 leagues frauges des lobes de la corolle. Va de 

 la plaine jusqu'a limite super ieu re des arbres.

Gentians. 



Fig. I. Spring-Gentian. Perennial, Besides 

 the noweringsboots are those which produce 

 flowers the next year of which the lower leaves 

 are largest. It is distinguished from No. 2 by 

 its more pointed leaves and the winged calyx. 



On marshy meadows and on Alpine pastures, 

 from the plain up to 3300 m. 



Fig. 2. Short -leaved Gentian. The lower 

 leaves are largest as in the Spring - Gentian 

 (Fig. 1), they are roundish and end with a short 

 point. The edges of the calyx are not winged. 



Turf, 1900-3000 m. 



Fig. 3. Bavarian Gentian. The lower leaves 

 are smaller. On the stem there are 2 3 pairs 

 of leaves. The corolla has a long tube and the 

 lobes form a flat disc. Alpine pastures, turf, 

 debris, 18003600 m (rarely at 1350 m). 



Fig. 4. Bladderlike Gentian. This species 

 is an annual. Characteristic of the species is 

 the greatly inflated calyx, the edges of which are 

 broadly winged (wings about half as wide as the 

 tube of the calyx). Swampy meadows, from 

 the plains up to the Alpine regions, but not 

 everywhere. 



Fig. 5. Small Gentian. This plant is also 

 an annual (on the whole rare among Alpine 

 plants), the wings are however absent from 

 the calyx and the flower is of an intense blue. 



Fig. 6. Stemless Gentian. Corolla bell- 

 shaped , widening from ite base. Lobes of the 

 calyx becoming gradually narrower from their 

 base, adhering. Leaves rather leathery, narrow 

 and pointed. Alpine pastures , 15002700 m. 



Fig. 7. Carved Gentian. Nearly allied to 

 the preceding species and between both there 

 are intermediate forms. Its chief difference 

 is that the calyx-lobes become at first narrower 

 above their base and then widen again and 

 finally spreadout. The leaves are broader, softer 

 and blunter. Alpine pastures, 15002700 m. 



Fig. 8. German Gentian. Annual with a 

 fringed opening of the corolla-tube. The flower 

 is of a greenish violet. Tube of the corolla 

 I'/s times as long as the calyx. 



On pastures , from the plains up to 2750 m. 



Fig. 9. Field Gentian. Distinguished from 

 the preceding species by the number of the 

 lobes of the calyx, the field gentian has 4 lobes, 

 two large and two small ones ; the german gentian 

 has generally 6 of equal size, more rarely only 4; 

 the colour of the corolla is also different; in 

 campestris it has a more bluish tint. In the 

 Grisons a white variety is often found in com- 

 pany with that of the common colour. 



Common on Alpine pastures, from 1500 to 

 2700 m, on the whole a more truly Alpine plant 

 than the preceding species. 



Fig. 10. Slender Gentian. The plant is an 

 annual and dies after ripening its seed. In 

 the interior of the corolla there are numerous 

 hairs. Meadows, sand, debris covered with 

 grass, snowvalleys*), from 19002600 m. 



Fig. 11. Fringed Gentian. Easily distingui- 

 shed from other native Gentians by the long 

 hairs on the margins of the lobes of the corolla. 



On pastures and dry slopes, from the plains 

 up to the tree-limit.
