294 Blue to Purple Flowers 



Campanula laslocarpa, or Arctic Harebell, is a low-grow- 

 ing species with linear acute sessile, usually entire upper 

 leaves, the lower ones being spatulate and narrowed into 

 petioles, while the bright blue flowers are nearly erect and 

 solitary on the short stalks. This Harebell grows on the 

 alpine summits. 



BROOK LOBELIA 



Lobelia Kalmii. Lobelia Family

 of Lobelia will easily recognize the mountain Brook Lobelia, 

 which usually grows at the extreme edge of a stream, or

 And bend, and wave, and flit." 



They are the pretty heralds of Autumn, some of them tall,
