A pond covered with duckweeds
A pond covered with duckweeds (Lemna minor and Wolffia columbiana) in late summer.

The duckweed family consists of floating plants, without leaves; instead they have a flattened or globose frond. Plants may or may not have roots. Most reproduction is vegetative by budding. However, the duckweeds do produce flowers and are the world's smallest flowering plants.
