(PLATE XXXVIII.) 



The flowers of this family have somewhat the look of the 

 Snapdragon. The purple Butterwort is common in many 

 parts of the north of England, Scotland, and Ireland, and 

 abounds in Switzerland, where also a larger kind is found 

 on the high mountains. P. Alpina (Fig. 66) resembles the 

 blue species, and bears a single delicate flower on a leafless 

 stalk about six inches high. The flower is yellowish- 

 white, and has two yellow spots on the mouth. The two 

 stamens are covered by the lips of the corolla, which is 

 lengthened into a short conical spur. The leaves are oblong, 

 of a pretty, tender, delicate, green, well described as looking 

 as though oiled all over. The whole plant is fragile, it 

 delights in wet, boggy, soil, and soon withers after being 

 gathered. It is almost impossible to dry it satisfactorily.
