Research‎ > ‎


Part of my research as a graduate student focused on the Tradescantia alliance, a group of closely related New World genera in the monocot plant family Commelinaceae. You can read my open-access publication on systematics and inflorescence structure in these plants over at Systematic Botany.

I maintain a handful of the (hardest to kill) species from this group in a living collection. I also have limited quantities of DNA and seed for additional species in the group, collected from the wild (Missouri, Arkansas, Texas, Mexico) and botanical gardens. If you are interested in working on Commelinaceae, please contact me.
