SWISS FLOWERS. 83 



bears an umbel of several yellow flowers. The calyx is 

 rather shorter than the tube of the corolla, which opens at 

 the top into a flat spreading five-lobed limb ; stamens five. 

 It may be known, like all the varieties of the Auricula, from 

 the plant being more or less covered with a white flour-like 

 powder. The blossom is yellow ; it is rarely found white. 

 The leaves are roundish, oblong, fleshy, and rather crenate ; 

 they are very smooth, except for the white powder above 

 mentioned. Calcareous rocks of the Alps and Jura : Mont 

 Pilatus, Rocks by the Pont de la Caille, Mont Semnoz near 

 Annecy, Pont de St. Clair, Col des Aravis, Dent de Nivolet 

 near Chambery. 



P. viscosa (Fig. 64). This pretty little flower has so 

 exactly the form of a small Auricula, that it may be re- 

 cognised at once. Its rosy-purple blossoms, which are large 

 for its size, form an umbel of from two to five on a stalk, 

 not more than an inch or two above the leaves, and almost 

 hiding them. The leaves are roundish, crenate, bordered 

 with thick-set clammy hairs, and viscid on both sides, as 

 are the calyx apd stems. It keeps its colour when dried. 

 Hocks of the high mountains : Alpes des Morcles, Vaud, 

 Gorge du Trient in Valais, Mer de Glace, Dent du Corbeau, 

 Valley du Foin in the Engadine. 



P. farinosa is also very pretty, with smaller flowers, more 

 in the cluster, and a longer flower-stalk.
