Duckweed collector

This rather odd photo uses flash at night to image duckweed on our indoor pond (an Affinity Pool).

Duckweed on our pond

The water fountains up through the grey pipe and shoots out into a thin, hemispherical sheet of  water.

Oddly, this water action seems to collect the duckweed inside the falling water. It's trapped there, it can't escape, but sometimes more duckweed gets sucked inside.

Duckweed normally floats on the water surface as a single layer. But with this collection action it soon becomes two, three or more layers deep inside the water envelope.

Duckweed is a flowering plant, surely one of the smallest possible such plants. It's not usually part of the life in our pond, but today I added some water lily plants to the mix and there was pondweed stuck to the lily roots.

Duckweed is another example of viriditas - see yesterday's post.
