294 Blue to Purple Flowers 



Campanula- lasiocarpa, 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 



Stems: leafy, glabrous, paniculately branched. Leaves: lower ones 

 spatulate, obtuse, almost entire ; upper ones sessile, linear, acute. Flow- 

 ers: in loose racemes; calyx-tube turbinate, hemispheric, lobes lance- 

 olate ; corolla-tube straight, oblique, divided to the base on one side, 

 two-lipped, irregularly five-lobed. 



Those who are famiHar with the cultivated garden species 

 of Lobelia will easily recognize the mountain Brook Lobelia, 

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

 half immersed in some warm wet swamp, where its grass- 

 like stems bearing their racemes of sky-blue blossoms, spring

 worts, and the Fly-spotted Orchis. 



LARGE PURPLE ASTER 



Aster conspicuus. Composite Family 



Stems: stout, rigid. Leaves: ovate, oblong, acute, serrate, veiny. 

 Flowers: in numerous corymbosely cymose heads; involucre broadly 

 campanulate, its bracts in several series ; rays in a single series, not 

 very numerous ; disk-flowers tubular, perfect. 



In August or September the mountain meadows and for- 

 ests teem with many of these flowers, for then 



" Everywhere the purple asters nod. 

 And bend, and wave, and flit." 



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

 handsome, and stately, like the Large Purple Aster; some
