Water Arum ^ ^^ e swamp flower resembling the 

 Calla palustris so-called calla-lily ; the latter is, of course, 

 White not a lily, and, curiously enough, not a 



June true calla, it is a Richardia. The deep 



green leaves of the water arum are long-heart-shaped 

 with long stems. The open and rolling edged spathe is 

 white above and greenish beneath. The yellow spadix 

 is entirely covered with flowers, the lower ones perfect, 

 i. e., with all the parts complete, and the upper ones 

 often staminate. Fertilization is assisted by insects and 

 pond-snails. " The berries, red and distinct, in a head like 

 those of the Jack-in-the-pulpit, are ripe in August. The 

 plant grows 5-10 inches high and is at home in cold 

 bogs, from Me., south to Va., and west to Minn. The 

 name Calla is ancient and obscure, palustris is the Latin 

 name for swamp.
