40 POPULAR GEOGRAPHY OF PLANTS. 



in both are much larger, as large as those of the Evening 

 Primrose, but white. A Siberian species of Clematis 

 (Atragene alpina] grows also in these forests ; the flowers 

 are generally blue, though occasionally white; a white 

 Fritillaria, if the petals were all extended, would give some 

 idea of the size and appearance of the latter. The seed- 

 down is extremely elegant, from the perfect regularity of its 

 long white feathers. One or two kinds of Heath too grow 

 here (Andromeda polifolia) , and the Bed Bearberry (Arbutus 

 Uva-ursi). And here is that flower that will be seen (and 

 one cannot help being glad to see it), Toad-flax (Linaria), 

 almost like a yellow Snapdragon ; everybody must know it, 

 it is so determined to poke its head out at the very top of 

 every hedge it grows in. Its near but humble little rela- 

 tion, the modest Eye-bright (Euphrasia), grows close by. 



Here is also our wayside Silver -weed or Goose-grass 

 (Potentilla anserina), and one of the Bedstraws (Galium 

 /boreale). Another of the Primrose tribe comes next, Tufted 

 Loose-strife (Lysimachia thi/rsiflora) , not growing like a 

 Primrose, on the ground, but tall and erect, with clusters 

 of little yellow flowers growing upon the sides of the stalk. 

 The beautiful heath -like Pyrola grow here too, some of 

 which we met with in the Polar regions.
