[Taxacom] Smallest Angiosperm

[Monique Reed]

I believe that species of Wolffia (Lemnaceae) are generally regarded as the smallest flowering plants.

Each plant is just a bit bigger than a printed period.  They reproduce mostly by budding and have neither leaves nor roots.  Flowers consist of a single stamen or a single pistil.

Lepuropetalon is tiny indeed, but next to Wolffia, it's a giant.
