 Serofulariaeeae (Figworts). 



The plants belonging to the family of the 

 figworta have an undivided, usually labiate 

 corolla, generally 2 long and 2 abort stamcus, 

 and a many-seeded capsule with two chambers. 



Fig. 1. Alpine Toad- Flax. Stem creeping 

 but the end bent upwards. Flowera violet, with 

 a long spur containing honey and with an orange 

 spot which shows insects the way to tbe bouey, 

 in the self coloured variety (coucolor) this spot 

 is absent. This plant it thoroughly characteri- 

 stic of rocky debris, eapec. of the calcareous 

 mountains and is often carried down by the 

 rivers to the plains. 1600 33' >0 m. 



Fig. 2. Alpine Bartsia. Easily recognised 

 by the glossy violet of the topmost foliage- 

 leaves. Pastures, belts of turf, from 1600 to 

 2800 m. 



Fig. 3. Dwarf-Eye-brlght One of the few 

 annual Alpine plants, often only a few centi- 

 metres high. Known by its labiated flower 

 with a yellow lip and by its bluntly notched 

 leaves; more rarely the flower is white with 

 violet stripes and with a yellow spot on the 

 lip. Alpine pastures from 10003000 m. 



Fig. 4. Yellow Lousewort Indicates poor 

 soil the corolla without a beak, on the outer 

 side hairless, under the apex is a blackish red 

 spot. Pastures, on grass, from about 16(0 to 

 2700 m. Only in the northern Alpine chain 

 from St. Gallen to Vaud; absent among the 

 central Alps, although as a rule northern species 

 prefer the central Alps. 



Fig. 5. Beaked Lousewort. Has red flowers 

 with a long beak. Spike short, with but few 

 flowers ; lobes of the calyx notched. Pastures, 

 turf, 18003000 m.

 from 18002700 m. 



Fig. 7. Leafy Lousewort. Flowers yellow, 

 without a beak and with hairs outside. A tall, 

 leafy, herbaceous plant which bears sessile leaves 

 even on the flower spike. Wildheuplatze*), 

 grassy precipices of debris, turf, from 1100 to 

 220U m. 



Fie:. 8. Flesh-coloured Lousewort. Charac-

 canton ofFreibourg; rare in the Valais only on 

 the primary formations and in Berne, common 

 in E. Switzerland.) 



Fig. 10. Whorled Lousewort Differing form 

 all other Louseworts by the stem bearing 4 6 

 leaves in the same node which thus form a 

 whorl. In pastures from 16002900 m (begin- 

 ning though not common at 1100 m).
