Pseudostellaria is a genus of flowering plants in the family Caryophyllaceae. Most of the 20 species occur in Asia. They are similar to Stellaria , differing in the morphology of the roots, fruit capsules and shallower notches of the petals. [2]

Rabelera holostea, known as greater stitchwort, greater starwort, and addersmeat, is a perennial herbaceous flowering plant in the family Caryophyllaceae. It was formerly placed in the genus Stellaria, as Stellaria holostea, but was transferred to the genus Rabelera in 2019 based on phylogenetic analyses. It is the only species in the genus Rabelera.

It is four-angled and usually at least partially coated in glandular hairs. The thick lance-shaped leaves are up to 15 centimeters long, oppositely arranged, and sometimes rough and hairy. The inflorescence is a cluster of flowers at the tip of the stem or in the leaf axils. Flowers occurring in leaf axils are sometimes cleistogamous, never opening. Open flowers have five white petals with two lobes at the tips and usually ten long stamens.

It is native to western North America from Alaska and northwestern Canada to California and New Mexico, as well as eastern Russia. It occurs in subalpine and alpine climates, in many types of moist, shady habitats. It is a rhizomatous perennial herb producing a prostrate to erect stem up to 25 centimeters long, taking a clumpy form. The thin oval leaves have smooth edges and pointed tips, and measure up to 2.5 centimeters in length. The inflorescence bears one or more flowers, each on a long pedicel. Each flower has five pointed green sepals, and some flowers have up to five deeply lobed white petals.
Stellaria crispa is a species of flowering plant in the family Caryophyllaceae known by the common names curled starwort and crisp starwort. It is native to western North America from Alaska south to California and Wyoming, where it grows in moist, shady habitat such as deep forests and streambanks. It is a rhizomatous perennial herb producing a mat of prostrate or trailing stems up to about 40 centimeters long. It is lined with opposite pairs of pointed oval leaves each 1 to 2 centimeters long. Single flowers occur in the leaf axils, each borne on a short pedicel. The flower has five pointed green sepals each a few millimeters long. Some flowers have one or more petals, but most lack these.
Stellaria littoralis is a species of flowering plant in the family Caryophyllaceae known by the common name beach starwort. 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 perennial herb that grows in a wide variety of habitat types, including tundra and taiga and many areas farther south with subalpine and alpine climates. It is extremely variable in morphology, its form depending on both genetic makeup and environmental conditions. It has a widely varying number of chromosomes. In general, it is a rhizomatous perennial herb forming mats or clumps, or growing erect. The stems may be short and simple or with sprawling and highly branched. The linear to lance-shaped leaves are usually 1 to 4 centimeters long and are oppositely arranged in pairs. The inflorescence bears one or more flowers, each on a short pedicel.
