Remnant American Chestnut (Castanea dentata) Near the Historical Western Range Limit in Southwestern Tennessee

The American chestnut (Castanea dentata) was once widespread in eastern North America and an ecologically important hardwood tree of deciduous forest communities prior to its near-eradication by chestnut blight (Cryphonectria parasitica). Remnant populations occur across much of its historical range, especially in older forests of the Appalachians and northeastern U.S. However, broad swaths of the southwestern portion of the species’ historical range remain poorly documented, potentially limiting the representation of genetic variation important for local adaptation in restoration efforts. Ongoing discovery and life-history characterization efforts for remnant C. dentata remains a priority to better understand the distribution and ecological status

Floristic Inventory of the James River Park System, Richmond, Virginia

We completed a floristic inventory of the James River Park System (JRPS), a ca. 223-hectare (550- acre) multi-unit park along the James River in Richmond, Virginia. The JRPS includes land within the riparian zone along a 13-kilometer (8-mile) stretch of the river that bisects the city, providing two million annual visitors with recreational access to the rapids along the “Falls of the James.” Although the vegetation within the park system is an important attraction for park-goers, information on the flora of the JRPS and this section of the James River corridor is limited. This study updates partial records of the

Plant Community Response to Hydrologic Restoration in the Great Dismal Swamp

Peatlands in the mid-Atlantic outer coastal plain region contain obligate hydrophyte species which were harvested and replaced by facultative tree species. The Great Dismal Swamp was drained from the colonial era until 1974, when water levels were partially restored. In September 2013, further restoration consisting of two large weirs followed extensive peat-burning fires. This study evaluated depth-to-water-table and vegetation structure both prior to and following weir operation. Wells were installed and depth-to-water-table was recorded continuously from 2013 to 2015 within six of the 15 forested stands where vegetation species dominance was quantified for tree, shrub, herb, and vine strata. Following

Noteworthy Collection: Florida

Xyris correlliorum, a rare species endemic to Highlands County, Florida, had not been seen there since 1996. This collection confirms that X. correlliorum is extant. Relevant aspects of this plant are also documented.

The Complete Plastid Genome of Neottia bifolia (Raf.) Baumbach (Orchidaceae): Insights Into Chlorophyllous and Achlorophyllous Plastid Genomes

Neottia bifolia is a small, terrestrial orchid distributed across the southeastern United States and northward up the Atlantic coast into Canada. The genus is well-studied as a model for the evolution of mycoheterotrophy, having both chlorophyllous and putatively achlorophyllous taxa. Despite this, the photosynthetic species, N. bifolia is relatively understudied. We provide results from the sequencing, assembly, and annotation of the complete plastid genome of N. bifolia and examine some evolutionary trends in the genus, using the 10 additional complete Neottia plastid genomes available on GenBank. We find that the plastid genome of N. bifolia is 156,533 base pairs in

A New Species of Clinopodium (Lamiaceae) from Alabama

Clinopodium talladeganum B.R. Keener & Floden is described as a new species from the Talladega Mountains, Alabama, United States. Morphological differences were compared and analyzed using PCA which supported it as a distinct morphological cluster when compared to the sympatric C. georgianum. An updated key to the genus is provided for the southeastern United States.
