WATER-PLANTAIN FAMILY. Alismaceae. 



A rather small family, widely distributed, growing in 

 fresh-water swamps and streams. The leaves are all 

 from the root, with long sheathing leaf-stalks, and the 

 flowers are regular and perfect, or with only pistils or only 

 stamens; the sepals three; the petals three; the stamens six 

 or more; the ovaries numerous, superior, developing into 

 dry, one-seeded nutlets. 



There are a good many kinds of Sagittaria, with fibrous 

 roots and milky juice; the leaves are usually arrow-shaped; 

 the lower flowers usually pistillate and the upper ones 

 usually staminate; the stamens are numerous and the 

 numerous ovaries are closely crowded and form roundish 

 heads. The name is from the Latin for "arrow, " referring 

 to the shape of the leaves.
