182 GOLDFISH VARIETIES AND 
SPATTERDOCK 
Among. the newer introductions into the aquarium are the submerged 
Spatterdocks. The large arrow- or spade-shaped leaves make a very 
characteristic appearance. Seedling plants gathered from lakes and ponds 
in the fall will do well in the aquarium over winter. If summer leaves 
appear and become too large for the aquarium the plant had best be re- 
moved. The Southern Spatterdock, Nuphar sagittefolia, does not

leaves will be longer. In October a new growth starts close to the thick, 
running root or rhizome. The leaves of this Spatterdock are of the bright- 
est green hue and do not darken in strong light. Where the rhizomes 
have been broken off they have a tendency to rot, eventually killing the 
plant. This seems to be overcome by planting in sweet soil.
