  • Tuesday, March 5, 6:30 pm – 8:30 pm Eastern- Native Orchids of Longwood Gardens, Online

    Pierre du Pont started Longwood Gardens’ native orchid collection in 1923 when he brought in Galearis spectabilis, an orchid that’s native to Pennsylvania. It’s one of several orchids that still grow on the Longwood property. This class not only takes you on a tour of Longwood’s native orchids but also shows you how this simple orchid purchase blossomed into a world-renowned conservation, plant breeding, and collections project.

  • Friday, April 7, 6:45 pm – Native Orchids and Mycorrhiza: Ecologically Complex Interactions

    The New England Botanical Club will host its 2017 Distinguished Speaker Dr. Dennis Whigham, Senior Botanist, Smithsonian Environmental Research Center and North American Orchid Conservation Center, on Friday April 7, beginning at 6:45 pm. He will speak on Native Orchids and Mycorrhiza: Ecologically Complex Interactions.

    The Orchidaceae is a species-rich family of flowering plants with more than 30,000 known taxa globally. Like most terrestrial plants, orchid species interact with mycorrhizal fungi, but unlike most plants, there is little evidence that the interactions are mutualistic. Most research indicates that orchids manage the plant-fungal interactions and they consume the fungi as sources of carbon and other resources. Dependency on fungi has evolved in a number of orchid lineages to a complete dependency on fungi resulting in many species being completely mycoheterotrophic. Understanding orchid-fungal interactions is not only interesting, but it is key to orchid conservation because all orchids have, at least, one life history stage that is completely depending on fungi.

    Dennis will focus on native orchids of the U.S. and Canada to describe the ecological challenges that remain obstacles to a more complete understanding of orchid-fungal interactions. He will link issues related to orchid ecology to a Smithsonian-initiated continental-scale effort to use an ecological model to conserve native orchids through a collaborative effort that is being developed by the North American Orchid Conservation Center (NAOCC). Dennis will describe how members of the New England Botanical Club have already provided important support for NAOCC and how members can become engaged in the only effort to assure the survival of an entire plant family at a continental scale. Meetings at Harvard University are held in Haller Lecture Hall (Room 102), Geological Museum, 24 Oxford St., Cambridge, MA 02138 (door to right of Harvard Museum of Natural History entrance).  Free and open to the public.  Image from www.wabash.edu.
