District of Columbia, United States
Locality: U.S. National Arboretum grounds, extreme northeast section in wooded wetland below the Dogwood Collection.
Habitat: Wild Habitat
Environment description: Wet, acidic stream valley/swamp in woods.
Associated species: Acer rubrum; Lindera benzoin; Mikania scandens; Clematis virginiana; Vitis labrusca; Arisaema triphyllum; Onoclea sensibilis; Toxicodendron radicans; Osmundastrum cinnamomeum.
Comment: A single individual was known at time of accessioning; several trees were noted on herbarium specimen collected in winter 2006, and four total plants have been verified as of early 2024. One of the last populations of the species in Washington, DC, where most of the former magnolia bogs were lost to development [three individuals were documented at this site in 2023 and 2024]. The area is sometimes referred to informally as a "magnolia bog", although the site may not strictly meet the definition of that term. Many invasive species are present at the time of accessioning in 2017, including invasive vines that may be choking the native vegetation.
