world's smallest flowering plant and seed

It makes sense that the world’s smallest flowering plant also produces the world’s smallest seeds: both records belong to Wolffia or the flowering duckweed.

The fruit of Wolffia augusta is about 0.2 mm (1/100th on an inch) long and weighs about 70 microgram - it is smaller than a single grain of salt!
