72 TYPICAL FLOWERS OF ALPINE PASTURES 



All.) is a rare plant, occurring chiefly in the Enga- 

 dine and in the Zermatt and Saas valleys. It is 

 remarkable for the length of the corolla tube as 

 compared with the calyx. It is believed to be the 

 only European Primula which does not possess long- 

 styled and short-styled flowers (see p. 68). The 

 leaves are similar to those of the Bird's-eye Primrose, 

 the lower surface being covered with a waxy powder. 

 Of the other species of Swiss Primulas, there is 

 little of interest to relate. Their leaves do not possess 

 a mealy powdering on either surface, and their rose- 

 or violet-coloured flowers have relatively short, common, 

 and individual stalks. The Hairy Primula {P. hirsuta, 

 All.) and the Entire-leaved Primula {P. integrifolia, 

 Linn.) are the commoner species.^ In the former the 

 leaves are thickly covered with sticky glandular hairs, 

 while in the latter they have only a few such hairs on 

 the margins. The Hairy Primula has strong-scented 

 flowers, and in the autumn the glandular hairs on 

 the leaves turn bright red in colour. It flourishes 

 on bare rocks, especially in granitic and gneissic 

 regions. As we have already remarked, it is one of 

 the parents of the cultivated Auricula. 



The Androsaces. 



Closely allied to the Primulas are the Androsaces, 

 also members of the order Primulacese, and charac- 



' Three other species, P. viscosa, All., P. aenensis. Thorn., and P. 

 glutinosa, Wulf, are found in Canton Graubunden. They are dis- 

 tinguished with diflSculty from the above and from one another.
