Great Duckweed
Spirodela polyrhiza
Size: to 0.1"
Habitat: floating free at surface
Notes: Among the smallest seed plants; important food for many waterfowl.
For their resistance to corrosion, rough handling, and general abuse, and their low price, aluminum tanks are very attractive to rental operations. That doesn't mean you should buy them for yourself.
