There are several plants called water chestnut; the edible one is
Eleocharis edulis as noted by T. Gray. The one with the beastly spines on
the fruit is Trapa natans. This has been introduced in a number of places
in eastern North America. One of its synonyms is Jesuit nut, which might
indicate that the French brought it with them from Europe.
