This species comes from a region long known to botanists as one producing many 
interesting plants. Although closely related to Nymphaea americana it seems amply 
distinct in its mych smaller flowers, smaller, greenish fruit, pointed leaves, smaller 
seeds, and numerous and conspicuous submersed leaves. While submersed leaves 
are occasionally found in N. americana they are never so numerous or conspicuous 
asin the New Jersey plant.
