The plant family Commelinaceae was named and described by Charles François Brisseau de Mirbel in Histoire Naturelle Générale et Particulaire des Plantes in 1804.
This family is commonly referred to as the Dayflower and/or Spiderwort family.
Plants of the World Online lists 39 accepted genera in this family as of 2-2521 when I last updated this page. That is down a few from the last update. Out of 39 genera, I am only familiar with Callisia, Commelina, and Tradescantia.
