Genus Pycnanthemum and the Perpetual Struggle for Identification presented by Dr. Derick Poindexter
Derick Poindexter is a postdoctoral researcher at the University of North Carolina Herbarium, where his current work focuses on plant systematics, evolution, floristics, and taxonomy. He holds an M.S. in Biology from Appalachian State University and a Ph.D. in Biology from UNC-Chapel Hill, where he utilized comprehensive methods to disentangle relationships in the genus Carex. As a native of the Southern Appalachians of North Carolina, much of Derick’s work has addressed issues regarding biodiversity and ecology within this region.
Species of the mint (Lamiaceae) genus Pycnanthemum Michx. (1803) have long been included in the horticultural trade, particularly in the United States where they serve not only an aesthetic role, but also provide considerable opportunity as a native attractant for pollinators. All currently described species of Mountain-mint are from eastern North America, except for a single California endemic, P. californicum Torr. ex Durand. In addition, the purported center of diversity for the genus is in our home state of North Carolina. Despite the small size of the genus (ca. 20 spp.), biologists have perpetually struggled with species identification, largely due to the complex sexual systems found in the group, including aneuploidy, allopolyploidy, and autopolyploidy. This talk will introduce various aspects of cultivation and species biology within this genus, as well as taxonomic complications.
REGISTRATION (for remote participation)
We will be meeting at Kathleen Clay Edwards Library Meeting Room (1420 Price Park Dr., Greensboro, NC 27410), but also will have a Zoom connection for those wishing to attend remotely. Please register in advance here to receive the link to the meeting. We hope we can set up the computer so sound is clearer for Zoom participants, but conducting a completely remote meeting is very different from sharing an in-person meeting. We so appreciate your interest in joining us and patience as we figure out how best to do this. Suggestions welcome! Send questions or suggestions to Triadco@ncwildflower.org.
This program is free and open to the public, and all are welcome!
Most programs are also posted on the NC Native Plant Society YouTube Channel within a couple weeks (when all goes well). Click on “Playlists” to see programs from each chapter. We will see how the recording works, and likely post the audio and slides if they work well. Click here to visit the Triad Chapter’s webpage.
Thank you for joining the North Carolina Native Plant Society as a member or guest to learn more about the ecology of our region!!! We look forward to seeing you!!!
We hope you’ll consider becoming a member, volunteering, and/or helping to promote our education and outreach work by sharing with your friends and family. Thank you again!
NOTE: The Triad Chapter has an informal listserv for members and friends in the Triad area who have events, native plants, or questions to share. To join the listserv, please write to Triadco@ncwildflower.org with your name and a little bit about your interest in being on the listserv (so we know you’re a real person in our community). NCNPS members receive notices from NCNPS, but that is not set up for community exchange, as the informal listserv is. We look forward to hearing from you!
