EXXEANDRIA. lOQ 



plant of this Order 3 of which there is but this one 

 known species; it grows in ditches, and on the 

 margins of rivers and ponds, chiefly in a gravelly- 

 soil, and blossoms iu July. Like several of our 

 aquatic flowers, it may be reckoned amongst the 

 most ornamental. If vegetables were classed accord- 

 ing to their natural affinities, this would rank among 

 the Lilies. It is sufficiently hardy to bear the cold of 

 Lapland.
