Cult. Eldtine is a genus of singular water plants. They all 

 grow under water except E. tripetala, which grows by the sides 

 of ponds ; therefore they should all be planted or sown in ponds 

 except the latter species, which should be planted on the borders 

 of a pond or canal, where they should be allowed to increase 

 themselves. A sandy or gravelly bottom suits them best. 

 Ripe seeds are easily transported in a vegetative state from the 

 places of their natural growth, or plants may be introduced.

Cult. All the species of this genus are inhabitants of moist 

 places, such as rice-fields, which are irrigated the greater part of 

 the year, consequently they will require to be kept in similar 

 situations in gardens, where they will ripen their seed. None of 

 them are worth cultivating, unless in botanic gardens.
