What is the Working Group?
A group of professional plant systematists with research interests in the Commelinid Monocots.* The working group was initiated with the "Commelinales Workshop," which took place at the Smithsonian Institution, National Museum of Natural History, 17-18 December 1999.

*Commelinids are equated here with "Commelinoids," a term used to describe an apparently natural assemblage of monocots (see below). The name "Commelinid" is preferred, as use of "Commelinoid" may cause confusion with the Commelinoideae, a subfamily of the Commelinaceae.

What are the Commelinids?
A monophyletic group of monocotyledonous angiosperms that are united by DNA sequence data as well as the general chemical apomorphy of cell-wall bound, UV-fluorescent ferulates (e.g., ferulic, coumaric, dicoumaric acids).
The Commelinids include the Arecaceae (palm family), Zingiberales (bananas, gingers), Commelinales (defined here as consisting of 4 families), Poales, sensu lato, and an assemblage of other groups of currently uncertain affinities.

Purposes of the Working Group
To enhance knowledge of and collaboration between plant systematists working on the Commelinid monocots.
