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. 
N. 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. 
Naphar advéna, or Yellow Water-Lily, has roots 
similar to V. 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. 
Pontedéria cordita, 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 sagittifélia, 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 Zobelia cardinalis, of our meadows, for the 
curious Sarracenia or side-saddle flower, and for many 
other bog or swamp plants,
