TWINFLOWER 



Twinflower (Linnaea). Linnaeus, the founder of 

 modern botany, has an appropriate memorial in this 

 little flower, one of the most delicate and beautiful 

 plants of northern woods. In Yellowstone Park 

 the twinflower is found only in the deepest and richest 

 forests. The woody stem trails along the ground, bear- 

 ing at intervals pairs of small, thick, round leaves, 

 each with two obscure notches near the top. At in- 

 tervals also the erect flow-stalks arise, leafless and 

 very slender, each bearing at the summit two small, 

 rose-white, bell-shaped, nodding flowers, with five 

 short, rounded lobes on the margins. This flower must 

 be sought in order to be seen, but it is worth the seek- 

 ing. 



Harebell (Campanula). This is another exceed- 

 ingly lovely flower, and it is very abundant at the mid- 

 dle altitudes, preferring moist locations, either partly 

 shaded or in the open. The stems are erect, very slen- 

 der, and somewhat branching, bearing a number of 

 exceedingly narrow, pointed leaves. At the top sever- 

 al nodding, bell-shaped flowers are borne; these are 

 about an inch long, bright blue or occasionally white, 

 with broad, blunt lobes on the margins.
