The white pistillate flowers develop on calyx tubesfrom 2 to 12 inches long. The Common Anacharis A. canadensis, Fig. 123, thrives fairly well inthe aquarium, is a good oxygenator, but is so weak and fragile that it willeasily break into sections. It should be planted in the sand or pebbles ingroups of 4 to 10 stalks. Freshwater fishes and goldfishes feed upon theleaves and in the aquarium frequently entirely destroy the plant. Whenfound in cold water streams the plants are more robust and the leaves 196.

It is avery pretty aquarium plant but difficult to maintain in satisfactory condi-tion, except with such fishes as will not molest it. Anacharis canadensis gigantea or Elodea canadensis gigantea (Hort.)Fig. i 24, is a cultivated species derived from A. canadensis^ the most gen-erally distributed native form. It has a thick jointed stem and leaves 1 to 1 y2 inches long, inwhorls of 4 to 8, with adense cluster of the longslender leaves at the endsof the stalks. It usuallygrowswithout much branch-ing.
