Nympujex. 



JK'^ympJuca odorhta Pond Lily, or sweet-scented Water Lily. 

 This queen of our aquatic flowers is so well known, that I 

 shall only quote from Dr. Bigelow, a few remarks on its 

 habit. 



"It is found in deep waters, where its roots are secured 

 from the frost in winter by a sort of natural hot bed being 

 thus provided for it. The roots creep through the muddy 

 bottoms of ponds, to a great extent. They are very rough, 

 knotted, blackish, and as large as a man's arm. The stalks, 

 both of roots and flowers, spring directly from the root.
