The first report of Azolla filiculoides in Virginia provides a key for distinguishing this species from Azolla caroliniana.

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.

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

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

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.

This article documents eight species new to Virginia and Maryland.

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.

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

We report seven collections of upright chickweed, Moenchia erecta (Caryophyllaceae), from Guilford County, North Carolina. These appear to be the first reports of this species in the state, the first collections in the southeast since 1958, and the first collections east of the Mississippi River since 1993.

Four species of vascular plants are reported here as new to Alabama: Geranium texanum, Gloriosa superba, Prunus yedoensis, and Trifolium echinatum; and one species was rediscovered after 125 years, Momordica charantia. The Prunus yedoensis record represents the first collection of this species from the Southeastern United States. The Gloriosa superba

Soldiers Delight Natural Environment Area and Wildlands, a biodiversity hotspot in the Maryland piedmont, conserves an endangered serpentine oak savanna (“barren”) ecosystem with numerous rare, threatened, and endangered species. White-tailed deer became conspicuous during daylight hours circa 1994. In 2008, a helicopter-mounted forward-looking infrared camera (FLIR) survey estimated 36 deer/km2
