Stellaria littoralis

Stellaria littoralis is a species of flowering plant in the family Caryophyllaceae known by the common name beach starwort.[1] It is endemic to the San Francisco Bay Area and North Coast of California, where it grows in moist coast habitat, such as marshes, bogs, and coastal bluffs. It is a rhizomatous perennial herb producing sprawling, branching stems which are four-angled and hairy in texture, reaching up to about 60 centimeters long. The lance-shaped or pointed oval leaves are up to 4.5 centimeters long and are oppositely arranged in pairs. The inflorescence bears several flowers, each on a short pedicel. The flower has five hairy, pointed green sepals each a few millimeters long. There are five white petals, each so deeply lobed it appears to be two.
