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.

round trip commute on a bicyclein the rain, tomorrow)
