The New England Botanical Society is holding monthly meetings in person and sometimes in Zoom. For Zoom meetings, members will receive the Zoom link in the monthly mailing. Non-member registrants will receive the Zoom link the day before the presentation.
Current Year Meetings
October 3-4, 2025
- Conference: Plant Migration in a Changing Climate
- Coastal Maine Botanical Gardens, Boothbay, Maine
- Please visit our conference page
November 7, 2025
- Dr. Chris Martine, David Burpee Professor of Plant Genetics and Research and Director of the Manning Herbarium, Bucknell University, Lewisburg, PA; and President-Elect of the Botanical Society of America
- Hybrid at Harvard University at 5:30pm
- “‘Discovering’ Species, Exploring Plant Partnerships, and Spotlighting Sexual Diversity While Using a SciComm & SciArt Underdog Outreach Approach”
- Abstract: The bush tomatoes (Solanum) of the Australian Monsoon Tropics have proven to be an ideal system for studying the ecology and evolution of plant reproductive systems and patterns in biodiversity. This talk will summarize two decades of field-, collections-, and lab-based research and the ways that this has spawned creative approaches for generating enthusiasm about plants, both inside and outside of the classroom.
- Non-members register here.
December 5, 2025
- Dr. Eric Doucette, State Botanist for the Maine Natural Areas Program
- Hybrid at Harvard University at 5:30pm
- “A Maine Botanist’s Trip to Western Newfoundland’s Limestone Barrens”
- Abstract: Western Newfoundland, particularly the Great Northern Peninsula that stretches towards Labrador, is home to some of the best examples of limestone barrens in eastern North America. Despite being large by New England standards, these natural communities are globally rare, occupy less than 1% of Newfoundland’s land area, and are of conservation concern. They support a unique assemblage of plants, adapted to the unique mineral profile of the soil, extreme wind exposure, cold temperatures, and periods of drought. The limestone barrens have long attracted botanists, with M.L. Fernald and others spending significant time collecting there. Botanizing there is an excellent way to understand regional floristic patterns, see plants that are extremely rare or absent in New England, and ponder the population dynamics of narrow endemics.

- “The Wonderful Diversity of Plant Photosynthesis”
- Abstract: Despite appreciating the importance of photosynthesis to both plant life and the planet more broadly, many of us may never spare a second thought to how photosynthesis has evolved. Over millions of years, plants have expanded into novel habitats, some of which are stressful—stressful enough that they can inhibit efficient photosynthesis. In turn, plants have evolved adaptations via changes to their photosynthetic machinery to cope with those stresses. This talk will introduce some of the marvelous variety of plant photosynthesis, how we think it evolved, and discuss what photosynthetic variation means for people, plants, and the planet.
March 6, 2026
- Dr. Weston Testo, Assistant Professor in the Department of Plant Biology at the University of Vermont and Director of the Pringle Herbarium
- Hybrid at Harvard University at 5:30pm
- “Phylogenomic Methods Reveal Ancient Hybridization in North American Royal Ferns”
- Abstract: Hybridization has been shown to drive speciation in many evolutionary lineages, especially amongst certain groups of plants, such as ferns. While most hybrids are derived from mating events between closely related species, some exceptional cases of hybridization between deeply divergent lineages (up to ~60 MY) are known. Using samples obtained from herbarium specimens, we provide genomic evidence for natural hybridization between two genera of royal ferns (Osmundaceae) from eastern North America. As the deepest hybridization event known in plants or animals, this finding provides a new upper bound for the amount of time that can pass before reproductive barriers develop and poses questions about reproductive isolation in ferns and other seed-free plants. This work also highlights the role that herbaria play in supporting evolutionary studies in the genomics age.
April 3, 2026
- Dr. Annise Dobson, Director of Research Programs and Associate Research Scientist at Yale University, New Haven, CT
- Hybrid at Harvard University at 5:30pm
- “Jumping Worms and the Challenge of Multiple Forest Stressors“
- Abstract: Across the Northeast, invasive jumping worms are rapidly altering forest ecosystems by consuming the leaf litter layer and transforming soil. This talk explores the impact of jumping worms and co-occurring stressors in the forest understory, where the below ground stress caused by worms combines with competition from invasive plants and overabundant deer that browse native seedlings. In addition, we will discuss the drivers of jumping worm invasion and outline strategies to limit their impact, providing a pathway to achieve our native plant gardening, conservation, and management goals.
May 1, 2026
- TBD
- Held at Native Plant Trust’s Garden in the Woods, Framingham, Mass.
