Mahonia is a genus of approximately 70 species of evergreen shrubs and, rarely, small trees in the family Berberidaceae, native to eastern Asia, the Himalaya, North and Central America. They are closely related to the genus Berberis and botanists disagree on whether to recognize a separate Mahonia. Many botanists prefer to classify Mahonia as a part of Berberis because several species in both genera are able to hybridize, and because there are no consistent morphological differences between the two groups other than the leaf pinnation. However, recent DNA-based phylogenetic studies retain the two separate genera, by clarifying that unifoliolate-leaved Berberis s.s. is derived from within a paraphyletic group of shrubs bearing imparipinnate evergreen leaves, which are then divided into three genera: Mahonia, Alloberberis, and Moranothamnus ; a broadly-circumscribed Berberis would also be monophyletic.
Pandanaceae is a family of flowering plants native to the tropics and subtropics of the Old World, from West Africa through the Pacific. It contains 982 known species in five genera, of which the type genus, Pandanus, is the most important, with species like Pandanus amaryllifolius and karuka being important sources of food. It is an ancient family dating from the early to mid-Cretaceous.
Dirca is a genus of three or four species of flowering plants in the family Thymelaeaceae, native to North America. The genus is named after Dirce in Greek mythology. The general common name for this deciduous shrub is leatherwood; other names include moosewood, ropebark and the Powhatan-derived name wicopy. The stems of Dirca are exceptionally pliable and the bark is difficult to tear by hand; for this reason, its stems were used by Native Americans in eastern North America as thongs or ropes. Members of the genus can grow to a maximum height of about three meters, and are often associated with rich, moist woods or slopes above creeks or streams.

Heteranthera limosa is an annual flowering plant in the water hyacinth family known by the common names ducksalad and blue mudplantain. It grows in shallow water or on mud. It is considered a threatened species in parts of the central United States, and an invasive species weed in California, where it is a nuisance in rice paddies. It is also occasional in Florida waterways.

Vallea ecuadorensis is a species of tree in the Elaeocarpaceae family. Although formerly considered endemic to Ecuador it has also been collected in Bolivia and Peru. This species occurs in subtropical or tropical moist montane forests, at 2500 – 3500 meters above sea level.
The Leatherwood Station Covered Bridge is a single span double Burr Arch Truss covered bridge structure that was built by Joseph A. Britton & Son in 1899. Originally it had sandstone abutments but when it was moved to Billie Creek Village they were replaced with concrete abutments with sandstone showing.
Dirca palustris, or eastern leatherwood, is a shrub that grows to a maximum height of about three meters. It is native to the eastern half of North America but uncommon, found in rich woods, and is occasionally cultivated. The species name, "palustris", means "of the swamps". It is often hard to recognize because the flowers, which come out just before leafing, last a very short time and D. palustris may be mixed in with the much more frequent Spicebush, which also has small yellow flowers that appear before the leaves and do so at just about the same time in the early spring. Its closest relative, the western leatherwood, lives across the continent in the San Francisco Bay Area. The species epithet palustris is Latin for "of the marsh" and indicates its common habitat.
Dirca occidentalis, the western leatherwood, is a deciduous shrub with leaves three to seven centimeters in length. Yellow flowers emerge prior to leafing. It grows on moist and shaded slopes. It is rare and endemic to the San Francisco Bay area of California. Its closest relative, Dirca palustris, lives in the eastern half of North America.
Phyllanthus caroliniensis, the Carolina leafflower, is a flowering plant native to the Americas, from the southeastern United States all the way to Argentina. The flowers are small and located where the leaf meets the stem.
Leucanthiza dircella is a moth of the family Gracillariidae. It is known from Québec, Canada, and the United States.
The Leatherwood Wilderness, a 16,838 acres (68.14 km2) federally designated wilderness area, is located within the Ozark-St. Francis National Forest in Arkansas is the largest wilderness area in Arkansas. The US Congress designated the Leatherwood Wilderness in 1984 and the US Forest Service manages the land.
Aletris farinosa, called the unicorn root, true unicorn, crow-corn, white colic-root or white stargrass, is a plant species found across much of the eastern United States. It has also been reported from the southern part of Ontario, Canada. It is known from every state east of the Mississippi River except Vermont, as well as Texas, Oklahoma, Arkansas and Louisiana.
Sagittaria ambigua, the Kansas arrowhead, is an aquatic plant species native to the central United States. It grows in wet areas, mostly along the shores of ponds and waterways.

Its habit is erect to sprawling, up to 0.4 meters in height. It flowers in summer and late spring, and summer and grows in moist, sandy soils.
