Here's the pic to prove it!
The green part is clearly the leaves of the plant, having a star-like appearance. The little brown proboscis-like thing with the black tip I'm guessing is a root...all plants first produce a root upon sprouting, Aldrovanda is no exception. This is the only time Aldrovanda makes a root.
I've been getting seed from plants for several months, after I squeezed a pod where there used to be flowers...and I was surprised when 5 or so black seeds spilled out. I've been collecting some in a tray of water, and I started leaving them outside in the sun. And this morning I discoved one sprouted!
