Bonamia grandiflora is a rare species of flowering plant in the morning glory family known by the common names Florida lady's nightcap, Florida bonamia, and scrub morning glory. It is endemic to Central Florida, where there are about 100 known populations remaining, many of which are within the bounds of the Ocala National Forest. The plant has declined in recent decades primarily due to the development of its habitat, which is being converted to urban zones and citrus groves. This is the primary reason that the plant was federally listed as a threatened species in 1987.
Euphorbia deltoidea is a species of flowering plant endemic to Florida in the United States. The taxonomy of the plant is difficult, with some authorities dividing it into four subspecies and some into three; also, it is frequently listed as a member of the old genus Chamaesyce. One subspecies, ssp. deltoidea, is a federally listed endangered species called deltoid spurge. It is found only in Miami-Dade County. Another subspecies, ssp. adhaerens, is often included with it under the name deltoidea instead of separately, making it difficult to keep count of how many endangered plants there are. This is generally dealt with by placing the "endangered species" label on any taxon within the species that is limited to Miami-Dade County, however many names they may have.
Euphorbia eleanoriae is a rare species of flowering plant in the euphorb family known by the common name Nā Pali sandmat. It is endemic to Kauaʻi, Hawaii. Like other native Hawaiian euphorbs it is called ʻakoko locally. This plant was only discovered in 1992 and described to science in 1996 as Chamaesyce eleanoriae. At that time there were fewer than 500 plants known, all occurring in small populations scattered across the sheer cliffs along the Nā Pali Coast of Kauaʻi. By 2001 the total population had already dropped; only three populations were found, for a total of fewer than 50 plants. The plant was federally listed as an endangered species of the United States in 2010.
Chrysopsis floridana is a rare species of flowering plant in the aster family, known by its common name, Florida golden aster. It is endemic to Florida in the United States, where it is known from Hillsborough, Hardee, Manatee, and Pinellas Counties. It is considered an endemic of the west-central coast of the state in the general vicinity of Tampa Bay. There are 17 to 20 occurrences, many of which have few individuals, but one of which has over one million plants. In 1986 the plant was added to the US endangered species list because it was becoming increasingly rare, it was growing only on private property, and its habitat was unprotected and being destroyed and degraded by a number of forces. It is found at Bell Creek Nature Preserve in Riverview, Florida.
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 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.
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.

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.
Galactia smallii is a rare species of flowering plant in the legume family known by the common name Small's milkpea. It is endemic to Florida, where it is known only from a few small patches of remaining habitat in Miami-Dade County. It is threatened by the destruction and inadequate management of its habitat. It was federally listed as an endangered species of the United States in 1985.
Lupinus aridorum is a rare species of lupine known by the common name scrub lupine. It is endemic to Florida in the United States, where there were 10 known populations remaining in 2003. Fewer than 6000 individual plants were counted. It is threatened by the loss and degradation of its habitat. The scrub lupine is a federally listed endangered species of the United States.
Nolina brittoniana is a rare species of flowering plant in the asparagus family known by the common name Britton's beargrass. It is endemic to Florida, where there are 72 known populations, only a few of which are large enough to be considered viable. It is federally listed as an endangered species of the United States.
Paronychia chartacea is a rare species of flowering plant in the family Caryophyllaceae known by the common names papery Whitlow-wort and paper nailwort.

Scutellaria floridana, the Florida skullcap, is a rare species of flowering plant. It is endemic to Florida in the United States, where it is known only from the Florida Panhandle. It is threatened by a number of human activities and its small population sizes make it vulnerable. It is a federally listed threatened species.
