Spirodela polyrhiza is the name, and it is definitely not frogbit.  It is
just a duckweed that gets a little larger than some of the other duckweed
species.  It often gets a purple color under the leaves.  Frogbit is genus
Limnobium.  It is floating and has leaves an inch or two in size with
petioles of an inch or so.

car with a flat tire.  (Meaning it isn't going to be nice doing the 20 mile
round trip commute on a bicyclein the rain, tomorrow)
