AQUATIC PLANTS OF FRESHWATER will develop even after the larger plants have been cleaned before intro- duction into the aquarium.- The dense growth probably acts as a shelter for these film-like algae or more secure anchors for their development. ANACHARIS This mosslike aquatic plant is variously known to botanists as Anacharis, Philotria or Elodea and commonly as Waterweed, Ditchmoss, Water Thyme, Water Pest and in the British Isles as Babington's Curse. There are 4 or 5 very similar American species which bloom from May to August, but are also propagated by a plentiful production of off- shoots which, attached or separate, rooted or floating, grow with amazing rapidity inanyditch^ stream or pond throughout the United States and North America except the extreme north. It is a slender wholly submerged plant with fragile jointed and branching stem, 4 inches to 3 feet long, dependent upon the depth of water, so weak that it mats together and decays when the water is withdrawn. The male and female flowers are borne on separate plants. The pistil- late flowers are raised to the surface by their long calyx tubes and the minute staminate flowers break off and rise to the surface to shed their pollen. The fruit ripens below the surface of the water. The plant also forms heavy buds in the Fall, which drop to the bottom and develop in the following Spring. It is a verit- able pest, as it chokes up canals and waterways. Anacharis canadensis (Mich.) A. alsinastrum /^RaK \ R"irr Toi io <-Ua r,r^a,~'.a„ .«„ i. II FIG. 123.

The Common Anacharis A. canadensis. Fig. 123, thrives fairly well in the aquarium, is a good oxygenator, but is so weak and fragile that it will easily break into sections. It should be planted in the sand or pebbles in groups of 4 to 10 stalks. Freshwater fishes and goldfishes feed upon the leaves and in the aquarium frequently entirely destroy the plant. When found in cold water streams the plants are more robust and the leaves 196
