water-spangles, Salvinia minima

Nothing like shooting in a controlled environment! I've seen water-spangles here in Adrian, Michigan three times. Twice in park fountains and once in a nursery, for sale to aquarium people. This was in the store. Now if things would just continue under control. Water-spangles have made a trip from their original homes in tropical America, to the stores, then aquariums or water gardens, then dumped in the wild (or fountains). And there you go, out of control. Here in the north they die in winter. But in the South they are invasive, quickly covering open water, crowding out native surface plants, and blocking light to the subsurface. Water-spangles have been reported from AL, FL, and GA. Cultivated, Lenawee Co MI, 6/17/15. Water fern family, Salviniaceae.
