This Florida-endemic mint is a perennial shrub with linear, aromatic evergreen leaves. The flowers are white to pale lavender-pink with a band of purple dots on the white throat. This species is endemic to Liberty County, and occurs in flat sandy areas (characterized by longleaf pine and turkey or bluejack oak) that are deeply dissected by steep-sided, moist ravines.
This rare mint was listed as federally endangered in 1993. There were seven known locations of this species, six of which were on private timber company land. Currently, one population on State land has disappeared, and The Nature Conservancy discovered two new locations. The primary threat to this species is habitat loss/degradation as a result of logging and conversion of its habitat for silviculture practices. Other threats include loss of suitable habitat from invasive species and fire suppression.
Euphorbia telephioides, a perennial herbaceous
plant of about 30-40 cm in height, is a threatened
species restricted to coastal Bay, Franklin, and Gulf
counties, Florida. It has been reported from xeric
to mesic pine flatwoods and in scrubby pinelands dominated
by wiregrass and/or Pinus palustris or P.
elliottii. Although uncommon, telephus spurge
has been observed growing in wetlands with seepage
slope species. Telephus spurge can be locally abundant
along disturbed sandy, sunny roads, and in sites with
bedding. It can be found sporadically abundant in
dense grass of unburned scrubby flatwoods, or in upland
communities, which have been historically burned with
a two to three year fire frequency.

Harperocallis flava is a grass-like perennial plant. Plants usually bloom from mid-April through May, with fruits maturing in July. The leaves are basal and narrow, and the yellow flowers are solitary, perfect, and born on a stalk much longer than the leaves. Typical of plants in the lily family, the flowers consist of six petals, six stamens, and superior ovary. The petals are 9 to 15 mm long and become green when the plant is in fruit. It reproduces both sexually via seeds and asexually via short rhizomes. This species is genetically uniform across individuals and populations.
Harper’s beauty is a monotypic genus, described in 1968 and placed on the federally endangered species list in 1979. It is endemic to the Florida Panhandle, and occurs in open pineland bogs and along moist roadside ditches of Bay, Franklin, and Liberty counties. The primary threat to these plants is the adverse modification of its habitat: forestry practices, fire suppression, and soil and hydrological disturbances. In addition, this species is threatened by its very limited range and small population number.

White birds-in-a-nest is endemic to the Florida
Panhandle, and occurs in Bay, Gulf, Franklin, and
Liberty counties. This species lives in open savanna,
in mesic flatwoods sites with longleaf pine and oaks.
It is a small herb-like plant with small clusters
of white buds and flowers that looks like eggs and
little bird heads in a nest. Plants usually flower
from May through July, and are visited by bees.

Paronychia chartacea comprises two endemic allopatric subspecies that differ in life history, habitat requirements and sexual morphology. Subspecies chartacea is a short-lived perennial that occurs on the Lake Wales, Winter Haven and Mount Dora Ridges of the central peninsula, while subspecies minima is an annual restricted to Washington and Bay counties in the western panhandle. Subspecies minima occurs primarily on the margins of karst ponds, and the only protected populations occur on the Econfina Creek Water Management Area; two-thirds of known occurrences are located on private land in imminent danger of being lost. The principal cause of decline is the loss of habitat through the conversion of scrub or xeric uplands for agricultural, commercial, residential, and recreational purposes.
Pinguicula ionantha is a carnivorous plant located in Bay, Calhoun, Franklin, Gulf, Liberty, and Wakulla counties, Florida. It inhabits seepage bogs, deep swampy bogs, ditches, and depressions in grassy pine flatwoods and savannas. It survives in shallow standing water or sometimes even submerged for several days after a heavy rain.
The plant has a rosette of up to 15 cm across of fleshy, bright green-yellow leaves with upward rolled edges. The flowers, produced on stalks of about 10 to 5 cm in height, possess five pale violet to white corolla lobes, and rise from late February to April according to temperatures.
Pinguicula ionantha responds strongly to prescribed fire, specifically
the timing of the fire event has an influence on fecundity.
This species is threatened by habitat degradation
due to lack of prescribed fire and shading by planted
pines, drainage, and degradation of water quality.
Ribes echinellum, a perennial deciduous
shrub, is a threatened species located along the north
shoreline of Lake Miccosukee near Monticello, Florida,
and in two locations, in South Carolina, McCormick
County: Stevens Creek and Sumter National Forest.
These disjunct populations may represent Pleistocene
refugia, remnants of what was once widespread Tertiary
vegetation. The present confinement of R. echinellum to two disjunct localities indicates that it is a
very rare species, yet in both locations the plants
are abundant. The sites have high floristic diversity,
dominated by a mixed hardwood forest containing deciduous
species, on mesic and well drained soils with an underlying
rock of limestone.

Rhododendron minus var. chapmanii is an
endangered species restricted to the Florida Panhandle,
known from only three populations: coastal Gulf County;
Liberty and Gadsden counties in the vicinity of Hosford;
and in Clay County on Camp Blanding Military Reservation.
The population near Hosford is the largest. The smallest
and most geographically isolated of these populations
is within the Florida National Guard post at Camp

The Florida skullcap, a federally threatened species, is found in Bay, Franklin, Liberty and Gulf Counties, FL. It is a perennial herb with square stems and opposite leaves. The flowers are solitary, with a bell shaped calyx and bright lavender-blue corolla. Bumblebees, megachilids and halictids are probably important pollinators. This species is most commonly found in pine flatwoods and savannas, and has a strong flowering response to recent burns. Plants flower from April through July and are most prolific after a fire. The primary threat to this species is habitat loss/degradation as a result of conversion of land to planted pine stands and fire suppression.

Spigelia gentianoides is a small herbaceous
plant found in fire-dependent ecosystems. This species
comprises two varieties: S. gentianoides var. gentianoides, known from only five populations
located in Jackson and Calhoun counties (Florida)
and Geneva County (Alabama); and S. gentianoides var. alabamensis, restricted to the Bibb
County Glades (Alabama). The plant is found on public
and private lands, and is not protected in the State
of Alabama. The primary threat to gentian pinkroot
is habitat loss and alteration. Factors contributing
to this threat include clearcutting and/or selective
thinning, mechanical site preparation, pine plantations,
disruption of pre-historical and historical fire regimes,
and permanent habitat loss through development.
