help to keep the plant in good health by furnishing 

 oxygen. (Hee Aquarium.) The plant should be potted, 

 and plunged not more than 18 inches below the .sur- 

 face of the water. For potting soil use a rich compost, 

 such as is recommended for Nymphseas. The water 

 should bo kept clean and sweet, and a temperature of 

 65*^ to 7~i° provided. Avoid direct sunlight. 



In Madagascar the streams often dry up, and the 

 tubers carry the plant over the dry season. In imitation 

 of nature some cultivators take the tubers out of the 

 soil, and leave them on a shelf in a hothouse during 

 the month of February. It is doubtful whether this is 

 necessary. Potting should be done while the plant is 

 in active growth, not dormant. Prop, by division.
