COMMON ARROW-HEAD, so called from ^Jan- 

 the shape of its leaf. This plant is one of the most 

 beautiful ornaments of our rivers, pools, and ditches. 

 The individual flowers are of a short duration, but indefinlte - 

 there is a succession of them through the months of 

 July and August. 



It has a bulbous root, containing a good deal of 

 flour, which may be easily extracted, to be used as 

 starch or as flour. The root itself is good food for 

 cattle. This plant, though totally neglected by us, is 

 cultivated in China, and supplies whole districts with 

 food.
