ners in every direction, forming new plants 

 and bringing forth the larger three-leaved 

 male, and the smaller female flowers. Both 

 are white and supported by long, slender 

 stems. The hair-like roots hang down in 

 the water. 



Propagation can be effected by runners, 

 or through winter-buds, which require the 

 same treatment as those of Utricularia. 

 Hydrocharis can be well recommended to 

 aquarists, not only as an aquatic of easy 

 and rapid growth and of great beauty, but 

 also as a plant greatly favored by vegetarian 

 fishes, amphibians, snails and other inhab- 

 itants of out and indoor aquariums. 



Small Duckweed (Lcmiia minor) with its 

 little bright green oval leaves is too gen- 

 erally known to need a long description. It 

 grows in springs or shallow ponds wherever 

 the water does not flow rapidly, frequently 

 covering large surfaces with a solid green 

 coating. Everv leaf forms one little rootlet 

 which hangs straight down into the water.
