Cornus florida, the flowering dogwood, is a species of flowering tree in the family Cornaceae native to eastern North America and northern Mexico. An endemic population once spanned from southernmost coastal Maine south to northern Florida and west to the Mississippi River. The tree is commonly planted as an ornamental in residential and public areas because of its showy bracts and interesting bark structure.
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large; botanists have described some 5,500 known species in about 90 genera – the largest being the "true sedges", with over 2,000 species.
Rhynchospora is a genus of about 400 species of sedges with a cosmopolitan distribution. The genus includes both annual and perennial species, mostly with erect 3-sided stems and 3-ranked leaves. The achenes bear a beak-like tubercule and are sometimes subtended by bristles. Many of the species are similar in vegetative appearance, and mature fruits are needed to make a positive identification.
Acer leucoderme is a deciduous tree native to the southeastern United States from North Carolina south to northwest Florida and west to eastern Texas. It lives in the understory in moist, rocky soils on river banks, ravines, woods, and cliffs. Although generally an uncommon tree, it is most often found in the inner coastal plain and Piedmont regions of Georgia.
Ostrya virginiana, the American hophornbeam, is a species of Ostrya native to eastern North America, from Nova Scotia west to southern Manitoba and eastern Wyoming, southeast to northern Florida and southwest to eastern Texas. Populations from Mexico and Central America are also regarded as the same species, although some authors prefer to separate them as a distinct species, Ostrya guatemalensis. Other names include eastern hophornbeam, hardhack, ironwood, and leverwood.
Cyperus polystachyos, also known as Pycreus polystachyos, and also called manyspike flatsedge in the US, or bunchy sedge, coast flatsedge, many-spiked sedge or Texas sedge in Australia, is a herbaceous species in the family Cyperaceae, widespread in tropical and subtropical areas around the world, sometimes extending its range into temperate regions.
Stewartia malacodendron, the silky camellia, silky stewartia or Virginia stewartia, is a species of flowering plant in the family Theaceae. It grows slowly into a large deciduous shrub or small tree, typically 3–4.5 m (10–15 ft) tall, but sometimes as tall as 9 m (30 ft). It is native to the southeastern United States.
Rhynchospora alba, the white beak-sedge, is a plant in the sedge family, Cyperaceae. It is a tufted herbaceous perennial around 50 cm tall, with white inflorescences that flower in August. The fruit of the sedge is a small achene with a characteristic beak-like cap. It is dispersed by wind or falls by gravity, leading to individuals existing in tight clumps. The species favours wet, acidic and nutrient poor soils, thriving in Sphagnum-dominated bogs, but also peaty grasslands. As such, it is often used as a positive indicator for bog and mire ecosystem health.
Carex buxbaumii is a species of sedge known as Buxbaum's sedge or club sedge. It is native to much of the northern Northern Hemisphere, from Alaska to Greenland to Eurasia, and including most of Canada and the United States. It grows in wet habitat, such as marshes and fens. This sedge grows in clumps from long rhizomes. The stems are 75–100 cm (30–39 in) in maximum height. The leaves are narrow and small. The inflorescence has a bract which is sometimes longer than the spikes. The fruits have dark-colored bracts and a sac called a perigynium or utricle which is gray-green and rough in texture.
Rhynchospora capitellata is a species of sedge known by the common names brownish beaksedge and brownish beaked-rush. It is native to eastern North America and a few spots in the western United States. It grows in wet habitat, such as swamps, springtime meadows, and moist areas in forests. It is a perennial herb producing clumps of stems 20 to 100 centimeters tall, each stem sheathed with several narrow, pointed leaves. The inflorescence is a cluster of brown spikelets each about 3 or 4 millimeters long.
Rhynchospora knieskernii is a rare species of sedge known by the common name Knieskern's beaksedge. It is endemic to the state of New Jersey in the United States, where it occurs naturallyin the Pine Barrens. Reports have cited it present in Delaware as well, but these populations appear to have been introduced. It is threatened by the destruction and degradation of its habitat. It is a federally listed threatened species of the United States.
Carex vaginata is a species of sedge known by the common name sheathed sedge.
Helianthus decapetalus, known by the common names thinleaf sunflower and thin-leaved sunflower, is a perennial forb in the family Asteraceae. It is native to the Eastern and Central United States and Canada, from New Brunswick west to Iowa, Wisconsin, and Ontario, south as far as Georgia and Louisiana. It produces yellow composite flowers in late summer or early fall.
Carex eburnea, known as ivory sedge, ebony sedge, and bristleleaf or bristle-leaved sedge, is a small and slender sedge native to North America, from Alaska and Newfoundland south to central Mexico.
Rhynchospora capillacea is a species of sedge known by the common names needle beaksedge, slender beakrush and needle beakrush. It is native to eastern North America from Labrador to Alberta, and south to Texas. It grows in wet, usually calcareous habitat, such as fens, sandy or stony shores, interdunal flats, and wet meadows It is a perennial herb producing clumps of stems 10 to 40 centimeters tall, each stem with very narrow, filiform leaves. The inflorescence consists of few (1-4) narrow brown spikelets each about 6 or 7 millimeters long.
Kobuleti Strict Nature Reserve is a protected area in Kobuleti Municipality, Adjara region of Georgia along the Black Sea coast in the northern part of the resort town Kobuleti. Kobuleti Protected Areas were established in 1998 to preserve unique wetland ecosystems recognized by the Ramsar Convention. Because of these wetland ecosystems, ancient forests, and the high biodiversity found within the reserve, it was inscribed on the UNESCO World Heritage List as part of the Colchic Rainforests and Wetlands in 2021.
Rhynchospora inexpansa, commonly called nodding beaksedge, is a species of flowering plant in the sedge family (Cyperaceae). It is native to North America, where it is found in the southeastern United States and West Indies. Its typical natural habitat is in moist meadows, flatwoods, and pond edges. It is a weedy species that responds positively to ecological disturbance.
Rhynchospora latifolia, known as sandswamp whitetop or tall whitetop sedge, is a species of flowering plant in the family Cyperaceae. Modified white leaves known as bracts grow atop this 1 to 3 foot tall, grass-like plant. It is found in much of the southeastern United States.
Rhynchospora megalocarpa, commonly called sandyfield beaksedge, is a species of flowering plant in the sedge family (Cyperaceae). It is native to North America, where it is found in the southeastern United States.
