18 FIELD CONVOLVULUS. 



hedge-bank, however, as it often does, its pink 

 cups opening only to the sunshine, it is a 

 beautiful adornment to the summer landscape, 

 and bees hover and hum about it continually. 

 Its presence is considered as a certain indica- 

 tion of a light soil, and its time for blooming 

 is in the months of June and July. Besides 

 this pretty pink Convolvulus, there is a much 

 larger kind, equally common in our woods and 

 hedges. This is the greater Bindweed. We 

 often see it hanging its large snowy bells over 

 the trees and shrubs of the garden, and it is 

 an ornamental plant, though, like the smaller 

 species, a very troublesome weed to the agri- 

 culturist. It is not often a companion of the 

 pink flower, as it flourishes chiefly in the 

 neighbourhood of streams and other moist 

 places. It is called by country people, Old 

 Man's Nightcap. There is also a wild Con- 

 volvulus on our sea-shores, called the Sea 

 Bindweed, with large rose coloured flowers 

 and succulent leaves.
