Ceratiola is a genus of flowering plants with a single species, Ceratiola ericoides, a shrub endemic to the Southeastern United States.
C. ericoides is commonly known as Florida rosemary, [3] , sand heath, [4] scrub rosemary, [5] or sandhill rosemary. [6]
C. ericoides is the sole species in the genus Ceratiola. [2] It was formerly included in the plant family Empetraceae, which since 2002 has been reclassified as the tribe Empetreae in the Ericoideae sub-family of the Ericaceae family. [3] [7]
C. ericoides is native to subtropical scrub and dry sandy habitats on the Atlantic Coastal Plain in the southeastern United States, including Georgia and South Carolina, throughout Florida, and in coastal counties of Alabama and Mississippi. [8] It commonly occurs in Florida scrubs together with sand pine and evergreen scrub oaks. [9]
Like sand pine, it is adapted to the harsh coastal environment where hot sun and fast draining white sandy soils are common. Cetatiola regenerate by seed after periodic forest fires. Its habitat is important for the endangered Florida sand skink (Neoseps reynoldsi) in central Florida.
Florida rosemary can grow to about 1.5 to 8 feet tall. It flowers in spring, summer and fall, and grows in the maritime hammocks. The name derives from the species' superficial similarity to the unrelated European shrub rosemary, familiar for its leaves used as a herb. Florida rosemary is not edible.
The Florida rosemary is dioecious and wind pollinated. Flowers are produced in the leaf axils on the previous years growth. [10] Plants do not produce seed until they are 10 to 15 years old. Seed production per plant increases until age 20 to 30 years. Seed production begins to fall off in plants more than 35 years old. [11] [lower-alpha 1] The fruit is a drupe containing two seeds. It is juicy and yellow in color. The fruit and seeds are consumed primarily by the Florida harvester ant, the oldfield mouse, the eastern towhee, and the Florida scrub jay. Seeds eaten by ants and mice are destroyed, while those in fruits eaten by birds pass through the birds' digestive tracts unharmed. Seeds in soil lose viability in less than 10 years. [13]
Florida rosemary plants release a chemical called ceratiolin into the soil, which breaks down into hydrocinnamic acid, which in turn inhibits the growth of other plants, and of rosemary seeds (a process called allelopathy). Decomposition by microbiota, fire, and other disturbances to the soil break down the hydrocinnamic acid, allowing other plants to grow, and rosemary seeds to sprout. [14]
Florida scrub communities typically experience fires at 15 to 100 year intervals, [15] , which kill all plants, including rosemary. [16] If a scrub patch burns less than ten years after a previous fire, there will not be seeds available in the soil to sprout into new rosemary plants. Johnson suggests that the falloff in seed production after a plant passes 35 years in age indicates that fires usually occur no more than 40 years after a previous fire, so that there is no selective pressure to continue producing large seed crops past 40 years. [17]
Kalmia is a genus of about ten species of evergreen shrubs from 0.2–5 m tall, in the family Ericaceae. They are native to North America and Cuba. They grow in acidic soils, with different species in wet acid bog habitats and dry, sandy soils.
Fred Gannon Rocky Bayou State Park is a Florida State Park located on the northwestern coast of the U.S. state of Florida, southeast of Niceville. The address is 4281 Highway 20. Native American middens and artifacts can be seen throughout the park.
The Ocala National Forest is the second largest nationally protected forest in the U.S. State of Florida. It covers 607 square miles (1,570 km2) of northern Florida. It is located three miles (5 km) east of Ocala and 16 miles (26 km) southeast of Gainesville. The Ocala National Forest, established in 1908, is the oldest national forest east of the Mississippi River and the southernmost national forest in the continental U.S. The word Ocala is thought to be a derivative of a Timucuan term meaning "fair land" or "big hammock". The forest is headquartered in Tallahassee, as are all three National Forests in Florida, but there are local ranger district offices located in Silver Springs and Umatilla.
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. It is endangered by residential, commercial and agricultural development, with the largest remaining block in and around the Ocala National Forest. Lake Wales Ridge National Wildlife Refuge also holds a high proportion of remaining scrub habitat, while the Archbold Biological Station near Lake Placid contains about 20 km2 (7.7 sq mi) of scrub habitat and sponsors biological research on it.
Warea carteri is a species of plant in the mustard family, Brassicaceae, known by the common names Carter's pinelandcress and Carter's mustard. It is an endangered, fire-dependent annual herb occurring in xeric, shrub-dominated habitats on the Lake Wales Ridge of central Florida in the United States.
Chionanthus pygmaeus is a rare species of flowering plant in the olive family known by the common name pygmy fringetree. It is endemic to Florida, where there are 46 known occurrences as of 2010. The plant is found in increasingly rare habitat in Central Florida that is being consumed for development, and some protected areas are not managed adequately. Most populations are small. It is a federally listed endangered species of the United States.
Cladonia perforata is a rare species of lichen known as Florida perforate cladonia and Florida perforate reindeer lichen. It is endemic to the state of Florida in the United States, where it is known from 16 populations in four widely separated areas of the state. It is native to a very specific type of Florida scrub habitat which is increasingly rare and patchy due to habitat destruction, degradation, and fragmentation. In 1993 this was the first species of lichen to be federally listed as an endangered species of the United States.
Dicerandra cornutissima is a rare species of flowering plant in the mint family known by the common name 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 15 known occurrences remaining. The plant was federally listed as an endangered species in 1985.
Eryngium cuneifolium is a rare species of flowering plant in the carrot family known by the common names wedgeleaf eryngo, wedge-leaved button-snakeroot, and simply snakeroot. It is endemic to the state of Florida in the United States where it is known only from Highlands County. It is one of many rare species that can be found only on the Lake Wales Ridge, an area of high endemism. It was federally listed as an endangered species of the United States in 1987.
Hypericum cumulicola is a rare species of flowering plant in the family Hypericaceae known by the common name highlands scrub hypericum, or highlands scrub St. John's wort. It is endemic to Florida, where it is threatened by habitat loss and degradation. It is a federally listed endangered species of the United States.

Its distribution spans Brevard, Broward, Dade, Highlands, Indian River, Martin, Osceola, Palm Beach, Polk, St. Lucie, and Volusia Counties.
Asclepias curtissii, or Curtiss's milkweed, is a rare species of flowering milkweed that is endemic to Florida's sandy areas. Curtiss's milkweed belongs to the subfamily Asclepiadoideae and the genus Asclepias. This dicotyledonous, perennial plant was placed on the endangered species list by the state of Florida to protect this rare milkweed. Although Curtiss milkweed is found all over Florida, the populations are very isolated and concentrated.
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.
Corema album, the Portuguese crowberry ; Spanish: camarina, is a species of flowering plant in the family Ericaceae endemic to the Iberian Peninsula, Aquitaine, and the Azores (sub-species), where it may also be considered a different species. Its white berries are known to have been consumed by people in the Iberian Peninsula at least since the Middle-Ages. The only other species of the same genus is Corema conradii, found in North America.
