AQUATIC PLANTS OF FRESHWATER 



and Marsh Buttercups; also the Castha 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 Plants. 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. 



Submerged and Partly Emersed Plants. Heteranthera renifor- 

 mis and H. zosteviefolia, Najas major, N. minor and N. flexilis, Zanichella 

 palustris, Hydrilla verticillata, Iso'etes lacustris, Pilularia globulifera, Sulularia 

 aquatica, Saururus lucidus, Cyperui alternifolium, C. gracilis, C. papyrus, C. 

 laxus and C. natalensis; Butomus umbellatus. Iris pseudacorus, Rumex aquaticus, 

 Oryza sativa, Zizania aquatica, Spargenium ramosum, Typha latifolia, T. 

 angustifolia and T. minima; Oenanthe fistulosa, Richardia albo-maculuta and 

 R. athiopica; Pontederia cordata, Veronica beccabunga, Myosotis palustris, 

 Acorus calamus, detha palustris, Berula aquatica, Triglochin palustris, Com- 

 arus palustris, Isolipis prolifera and /. gracilis, Scirpus radicans, Carex 

 japonica-marginatis, Menyanthes trifoliata, Menth aquatica. Nasturtium 

 officinale, and many others. 



Plants with Floating Leaves. Other than those already men- 

 tioned are Alisma natans, Fillarsia nymphaodes and V. humboldtiana; Poly- 

 gonum natans, Aponogeton distachyus and others. 



Floating Plants. In addition to those heretofore mentioned are 

 Stratiotes aloides, Aldrovandia vesiculosa; and the Mexican species, Salvinia 

 elegans. 



Of this wide range of plants selection may be made of those best 

 adapted to grow entirely submerged, partly submerged, floating on the 

 water, or together with many species of .ferns, on the rocks or planted 

 in pots.
