Water Plants, — Reference has already been made to Nelum- 

 bium speciosum, and the lotus {NympJicea) which are seen in all 

 still waters. In other respects the ponds and running streams 

 are infested with the usual water plants. Thus the aquatic 

 dicotyledons principally belong to the HALORAGEiE, with some 

 representatives amongst the Onagrarie^, Lentibularirie^, &c. 

 A common floating or creeping herb with alternate oval leaves and 

 yellowish flowers is seen in all swamps and brooks. This is 

 Jiissieua repens common in most tropical countries including 

 Australia, as far south even as Victoria and South Australia. 

 There are curious floats of cellular tissue attached to the sub- 

 merged nodes of the stems. The HALORAGEiE are a nearly allied 

 order including the Water-chestnuts ( Trapa), important food-plants 

 in north-west India and China, the Mill-foils {Myriopliylluni), the 

 Horn- worts {Ceratophylkim), and the Mare's-tail (^Hippuris), with 

 that universally difiused small smooth water-weed or star-wort
