 minees, angles du calice non alles.

 sions.

 pointues et les angles alles du calice. 



Pres marecageux de la plaine, päturages

Gentians. 



Fig. 1. Dwarf Gentian. Corolla bell- 

 shaped, widoning froni its base funnellike. 

 Lobes of the calyx becoming gradually nar- 

 rower from their base, adhering. Leaves 

 rather leathery, narrow and pointed. 



Alpine pastures, 1500—2700 m. 



Fig. 2. Carved Gentian. Nearly allied 

 to the preceding species and between botli 

 there are intermeüiate forms. Its chief dif- 

 ference is that the calyx-lobes become above 

 their base at first narrower and then widen 

 again and that they stand otf. The foliage 

 leaves are broader, softer and biunter. 



Alpine pastures, 1500—2700 ni. 



Fig. 3. Bavarian Gentian. The leaves 

 of the radical rosette become smaller lower 

 down. On the stem are 2 — 3 pair of leaves. 

 The corolla has a long tube and the lobes 

 form a Hat disc. 



Alpine pastures, turf, debris, 1800 to 

 3600 m. (rarely at 1350 m.). 



Fig. 4. Sliort-Ieaved Gentian. The leaves 

 of the radical rosette become larger further 

 down as by the Spring-Gentian (Fig. 7), 

 they are roundish and end with a short point. 

 The edges of the calyx are not flanked. 



Turf, 1900—3000 m. 



Fig. 5. Tender Gentian. The plant is 

 an annual, it dies after ripeningits seed and 

 possesses no non-flowering rosettes of leaves. 

 In the interior of the corolla there are mach 

 dissected fringes. Calyx, corolla and sta- 

 mens are quadruple, the corolla is violet, 

 rare ! 



Pastures, sand, d(5bris covered with 

 grass, snowhoUdVs, from 1900—2600 m. 



Fig. 6. Snow- Gentian. This plant is 

 also an annual (which is on the whole rare 

 by Alpine plants), the fringes are however 

 absent and the flower is of a more intense 

 blue. The hrilliant starshaped flowers of 

 this species which are often very small are 

 among the most graceful forms to which 

 the Alps have given birth. 



In the Short grass of the pastures, snow- 

 hollows, 1800—2600 m. 



Fig. 7. Spring-Gentian. Perennial, be- 

 sides liowering stems there are therfore 

 also non-fiowering rosettes. Leaves becoming 

 constantly larger lower down. It is dis- 

 tinguished from No. 4 by its more pointed 

 leaves and the flanked margins of its calyx. 



On marshy meadows and on Alpine 

 pastures, from the piain up to 3300 m. 



Fig. 8. German Gentian. Annual with 

 a bearded opening of the corolla-tube. The 

 flower is of a dull violett. Tube of the co- 

 rolla 12 times as long as the calyx. The 

 similar G. campestris has only 4 sepals, the 

 very nearly allied obtusifolia has biunter 

 leaves and the tube of its corolla is hardly 

 longer than the calyx. 



On pastures, from the plains up to 

 2750 m. 



Fig. 9. Ciliated Gentian. Easily dis- 

 tinguished from all native Gentians by the 

 long fringes on the margins of the lobes 

 of the corolla. 



On pastures and dry slopes, from the 

 plains up to the tree-limit.
