PLANTS FOR THE AQUARIUM. 71 



ing it out by one of his successors, I understand this rare 

 variety was destroyed. I fear that no more of it can be 

 obtained, as there was but one spot in the pond where it 

 was found, and I thought at the time that Mr. Carter and 

 myself took possession of all the roots. 



IV . Odorata minor, is a rare variety with very small flow- 

 ers and leaves, which I have found in some ponds, but 

 cannot remember where. These varieties of the white lily 

 will be sufficient for a small aquarium but if it be of 

 larger dimensions, there are a number of other species 

 of native aquatic plants, which may be introduced. 



Nupaar advna, or Yellow Water-Lily, has roots 

 similar to JV. odorata ; it has a very curious flower, but 

 the odor of it is the opposite of that flower, for the smell 

 is anything but agreeable. 



Pontedtfria cordata, or Pickerel-weed, is found in 

 shallow water ; its tall spikes of blue flowers are quite 

 ornamental. For this plant the soil should be raised to 

 within one foot, or foot and a half, of the surface of the 

 water. 



Sagittaria sagtttifdlia, is a handsome plant found 

 about the margin of ponds and brooks in shallow 

 water. Its white flowers arranged in whorls of three, are 

 produced in July and August ; the depth of water over 

 these roots need not be more than 3 or 4 inches. A por- 

 tion of the soil on the margin may be raised a few inches 

 above the water level, which will be a suitable place for 

 the beautiful Lobelia cardinalis, of our meadows, for the 

 curious Sarracenia or side-saddle flower, and for many 

 other bog or swamp plants.
