7o OUVIRANDRA FENESTRALIS. 



The plant delights in a rich soil similar to Nymphseas, a warm house, 

 the water temperature from 65° to 75°, partial shade, and a wooden vessel in 

 preference to an)'thing else. vSome of the finest specimens seen have been 

 grown in tubs — half kerosene barrels. It is unnecessary to change the water, 



as when the plants are in a healthy condition they oxygenate the water and 

 keep it clear, but confervse will occasionally appear. The best means to clean 

 this off and add to the health of the plant is to introduce a few tadpoles or 

 water snails.
