AQUATIC PLANTS OF FRESHWATER 

and Marsh Buttercups; also the Cetha or Marsh Marigolds, the Typha 
or Cat Tails, the Trollius or Globe Flowers, and many others enumerated 
in the Florists’ catalogues, will produce most beautiful foliage and flower 
effects. 
If the pond is a natural basin, the plants may be set into the mud 
at the borders, but in cement tanks they should be planted in pots and dishes 
and these screened or hidden with rockwork. 
TERRARIUM AND AQUA-TERRARIUM Pants. In addition to most 
of the foregoing aquarium plants, Europeans collect or cultivate a consid- 
erable number of native and exotic aquatic and semi-aquatic plants for the 
terrarium and aqua-terrarium; of which, for brevity, only the botanical 
names will be given, as the most of them have no popular names. Many 
of the following may be obtained of florists or collected in bogs, along 
canals and other natural waterways.
