Lemnacece, which are the smallest known Phanerogams, are intermediate between Naiadece and 

 Aroidece ; they are closely allied to the latter through the genus Pistia, which approaches them in inflo- 

 rescence and the structure of its seeds. They are found in stagnant water in all climates, but especially 

 in temperate regions ; they are rarer in the tropics on account of the heat which dries up the swamps, and 

 the torrents of rain which violently agitate the water. Their part in nature seein.s to be the protection 

 from the solar light of the inferior organisms of the Animal Kingdom which live in swamps, and at the 

 same time to serve them for food.
