Navarretia fossalis is a rare species of flowering plant in the phlox family known by the common name spreading navarretia. [1]
The plant is native to southern California and Baja California, where it is known only from vernally wet areas, such as vernal pools, ditches, and other areas that are wet or flooded during the rainy season and dry the rest of the year. Many of these habitat areas have alkali soils arranged in uneven mounds and depressions that collect water and drain slowly before drying up. [2]
The plant became a federally listed threatened species in the United States in 1998, when there were approximately 30 occurrences of the species remaining in Southern California and about nine left across the border in Baja California. [2] By 2009, an additional 17 occurrences had been documented. [2] The plant often occurs with Psilocarphus brevissimus . [3]
Navarretia fossalis is a hairy annual herb producing a spreading stem up to about 15 centimeters high. The hairless leaves are up to 5 centimeters long and are divided into narrow linear lobes that turn spiny sharp when dry.
The inflorescence is a flat-topped head 1 or 2 centimeters wide filled with lobed bracts and clusters of flowers. The white or purple-tinged flowers are under a centimeter long and have corollas divided into minute narrow lobes under a millimeter long.
The fruit capsule yields a clump of tiny seeds that remain stuck together until they become wet, turning into a sticky, separating mass.
Blennosperma bakeri is a rare species of flowering plant in the daisy family known by the common names Baker's stickyseed and Sonoma sunshine.
Eryngium racemosum is a rare species of flowering plant in the family Apiaceae known by the common name delta eryngo, or delta button celery.

It is endemic to California, where it is known from vernal pools and similar wet habitat in the Central Valley and certain areas of the Central Coast Ranges and southern California coast. This is a decumbent to upright perennial herb with spreading branches up to half a meter long. The lance-shaped to oblong leaves may be up to 24 centimeters long. The edges are deeply cut into narrow, sharp-pointed lobes. The inflorescence is an array of somewhat rounded flower heads surrounded by several narrow, pointed bracts with spiny edges. The head blooms in whitish petals.

Navarretia leucocephala is a species of flowering plant in the phlox family known by the common name whitehead pincushionplant, or whitehead navarretia. It is native to North America, including much of the western United States and central Canada. It generally grows in wet or moist terrestrial habitat such as vernal pools.
Navarretia nigelliformis is a species of flowering plant in the phlox family known by the common name adobe navarretia. It is endemic to California, where it is known from the Central Valley and adjacent mountains. It grows in vernally wet depressions in clay soils, such as vernal pools.
Navarretia peninsularis is an uncommon species of flowering plant in the phlox family known by the common names Baja navarretia or Baja pincushionplant. It is native to southern California and Baja California, where it is an occasional member of the flora in wet spots in mountain forests. It is a hairy, glandular annual herb growing up to about 25 centimeters in maximum height. The leaves are 1 to 3 centimeters long and are divided into many very narrow linear or needlelike lobes. The inflorescence is a head of flowers lined with leaflike bracts. The lavender flowers are just under a centimeter long.
Navarretia prostrata is an uncommon species of flowering plant in the phlox family known by the common names prostrate pincushionplant and prostrate vernal pool navarretia. It is endemic to California.
Navarretia subuligera is a species of flowering plant in the phlox family known by the common names awl-leaf pincushionplant or awl-leaved navarretia. It is native to southern Oregon and northern California, where it grows in open, wet habitat, such as meadows and vernal pools. It is a hairy, purple-colored annual herb growing up to about 16 centimeters tall. The leaves are divided into many linear lobes. The inflorescence is a cluster of many flowers surrounded by leaflike bracts with awl-shaped lobes. The flowers are white and under a centimeter in length.

It is native to southern San Diego County, California, where it is known only from Otay Mesa near the border with Baja California. It was identified on land south of the Mexican border, but these occurrences have probably been extirpated. It is now known from seven vernal pool complexes just north of the border, and it is a federally listed endangered species of the United States.
Eryngium pendletonense is a rare species of flowering plant in the carrot family known by the common name Pendleton button-celery. It is endemic to northern San Diego County, California, where it is known from four occurrences along the coastline between Oceanside and the Orange County border, including land within Camp Pendleton. It grows on vernally moist coastal grassland and coastal sage scrub habitat with clay soils. It was first described as a species in 1999.
