Endemism is the state of a species only being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be endemic to that particular part of the world. An endemic species can also be referred to as an endemism or, in scientific literature, as an endemite. Similarly many species found in the Western ghats of India are examples of endemism.
Florida scrub is a forest ecoregion found throughout Florida in the United States. It is found on coastal and inland sand ridges and is characterized by an evergreen xeromorphic plant community dominated by shrubs and dwarf oaks. Because the low-nutrient sandy soils do not retain moisture, the ecosystem is effectively an arid one. Wildfires infrequently occur in the Florida scrub. Most of the annual rainfall falls in summer.
Garberia is a monotypic genus of flowering plants in the family Asteraceae, containing the single species Garberia heterophylla. It is endemic to Florida in the United States, where it is distributed in the northern and central counties. The plant is known commonly as garberia and Garber's scrub starts.
Hartwrightia is a genus of North American flowering plants in the tribe Eupatorieae of the family Asteraceae. The genus contains a single species, Hartwrightia floridana, native to the US states of Georgia and Florida. The species is sometimes referred to by the common name Florida hartwrightia.
Conradina is a genus of flowering plants in the mint family, Lamiaceae. Its common name is false rosemary, or rarely, short leaf rosemary. There are 7 species of Conradina, all native to the southeastern United States. Conradina verticillata grows on the Cumberland Plateau in Kentucky and Tennessee. The other five grow mainly in Florida. All of the species are closely related and there is some doubt about whether they are all separate. Most species occupy xeric habitats with well-drained soils composed of white sand. The genus Conradina was established by Asa Gray in 1870. It was named for the American botanist Solomon White Conrad.
Pycnanthemum is a genus of herbaceous plants in the mint family (Lamiaceae). Species in this genus are often referred to as "mountain mints" and they often have a minty or thyme-like aroma when crushed. All species of Pycnanthemum are native to the United States and Canada. The center of diversity for the genus is North Carolina with 13 of the 20 species having been collected therein. Nineteen of the 20 species of Pycnanthemum occur in the Eastern US and Canada, and one disjunct species occurs in California and Oregon.
Conradina etonia is a rare species of shrub in the mint family known by the common name Etonia rosemary. It is endemic to Putnam County, Florida, where it is known from about 8 populations on Etoniah Creek State Forest containing fewer than 1000 total individuals. It has a specific habitat requirement and the main threat it faces is destruction and degradation of its habitat. It is a federally listed endangered species of the United States.
Dicerandra christmanii is a rare species of flowering plant in the mint family known by the common names Garrett's mint, yellow scrub balm, and Lake Wales balm. It is endemic to Highlands County, Florida, in the United States, where it is known from only four sites on the Lake Wales Ridge. All are contained within a tract of land measuring 6 kilometers by 3 kilometers. The plant is steadily declining due to the destruction and degradation of its habitat, and only one of the four occurrences is on protected land. It is a federally listed endangered species.
Dicerandra cornutissima is a rare species of flowering plant in the mint family known by the common names longspurred mint, longspurred balm, and Robin's mint. It is endemic to Florida in the United States. It is found in Marion County, and possibly Sumter County, but it may have been totally extirpated from the latter. There are 12 known occurrences remaining as of 2017, down from 15 in 2000. The plant was federally listed as an endangered species in 1985.
Dicerandra frutescens is a rare species of flowering plant in the mint family known by the common names scrub mint and scrub balm. It is endemic to Highlands County, Florida, where it is known only from the Lake Wales Ridge. Its habitat is quickly being lost as it is converted to residential and agricultural use. It was federally listed as an endangered species of the United States in 1985.
Dicerandra immaculata is a rare species of flowering plant in the mint family known by the common names Lakela's mint, Olga's mint, and spotless balm. It is endemic to Florida in the United States, where it is known only from Indian River and St. Lucie counties. There are seven occurrences of the plant, two of which are scheduled for destruction as the land is cleared for development. The plant was federally listed as an endangered species in 1985.
Dicerandra is a genus of flowering plants in the mint family. Dicerandra comprises 11 species: six perennial and five annual species. The perennials have narrow ranges in Central Florida with small population sizes and only occur on ancient dune ridges along the Lake Wales Ridge or the Atlantic Coastal Ridge; the annual species occur more broadly on sandhill habitats to the north. The perennials’ habitat has been severely fragmented due to human development over the past century. As a result, all perennial species except one are listed as federally endangered. Annual species of the clade have large ranges when compared to perennial members, with distributions of annuals ranging for hundreds of miles from the Panhandle of Florida to southeastern Georgia, with the exception of Dicerandra radfordiana which is endemic to two sites along the Altamaha river. The genus is characterized by hornlike spurs on their anthers.
The Florida peninsula inland scrub is a shrubland community found on the Florida peninsula. The largest remaining blocks of inland scrub are in and around the Ocala National Forest and in the Lake Wales Ridge National Wildlife Refuge. The Archbold Biological Station near Lake Placid contains about 20 km2 (7.7 sq mi) of scrub habitat and sponsors biological research on it. The scrub occurs on a series of north-south running ridges composed of sand derived from ancient dune fields. The soil, a type of entisol, is derived from quartz and is low in organic matter, silt, and clay. Because the low-nutrient sandy soils do not retain moisture, the ecosystem is effectively an arid one.
Pamela Soltis is an American botanist. She is a distinguished professor at the University of Florida, curator at the Florida Museum of Natural History, principal investigator of the Laboratory of Molecular Systematics and Evolutionary Genetics at the Florida Museum of Natural History, and founding director of the University of Florida Biodiversity Institute.
The Sand Prairie-Scrub Oak State Nature Preserve, formerly called the Mason County State Wildlife Refuge and Recreation Area, is a State Natural Area and Nature Preserve located in the U.S. state of Illinois. Containing 1,460 acres, it is a dedicated state nature preserve. It is located in western Mason County. The nearest town is Kilbourne, Illinois and the nearest numbered highway is Illinois Route 97. It contains fragmentary examples of the ecosystem described in its name.
Dicerandra densiflora, the Florida balm, is a species of flowering plant in the mint family known by the common names scrub mint and scrub balm. It is native to North Central Florida, where it occurs along sand hill habitats. It is a member of the annual subclade of Dicerandra. D. densiflora grows up to 2 ft (61 cm) tall. Flower petals are lavender to purple in color with dark spots.
Dicerandra fumella is a species of Dicerandra native to the Florida Panhandle. It was formerly classified as a variety of Dicerandra linearifolia. A hybrid zone between Dicerandra fumella and Dicerandra linearifolia var. robustior is located in the Marianna Lowland, west of the Apalachicola River in Florida.
Dicerandra linearifolia, or coastal plain balm, is a species of Dicerandra native to the Southeastern Coastal Plain, United States.
Dicerandra odoratissima, commonly known as the rose balm, is a species of Dicerandra native to the Southeastern Coastal Plain, with a geographic range that extends from eastern Georgia to southern South Carolina. Kral (1982) originally suggested that this species was so distinct from the remaining members of the genus that it should be placed in a separate section or a distinct genus. Today, D. odoratissima and its close relative D. radfordiana are members of the Lecontea clade.
Dicerandra thinicola, known as Titusville mint, is a species of Dicerandra native to the Atlantic Coastal Ridge along the Central Florida coast. It is restricted to a 50-km range, and all known natural populations of D. thinicola are located in Brevard County, Florida, near the city of Titusville. Most populations are located on private lands with conservation easements. The Dicerandra Scrub Sanctuary was created in 2002 on public lands in order to protect populations of this species from human development.
