Stellaria graminea | |
Stellaria graminea is a species of flowering plant in the family Caryophyllaceae known by the common names common starwort, [1] grass-leaved stitchwort, [1] lesser stitchwort [2] and grass-like starwort. [3]
It is a rhizomatous perennial herb producing branching stems which are prostrate, sprawling, trailing, or erect, and reach up to about 90 centimeters long. The stems are four-angled, weak, and hairless. It is lined with pairs of linear or lance-shaped leaves, each 1–4 centimetres (0.4–1.6 in) long. The leaves are smooth-edged and hairless except for some hairs lining the bases. The inflorescence bears several flowers, each on a short pedicel. The flower has five pointed green sepals each a few millimeters long which are usually lined with hairs. There are five white petals, each so deeply lobed it appears to be two. The seeds are reddish brown in colour and are 1 millimetre (0.04 in) in diameter. [1] It bears 10 stamens. [4]
It is native to Eurasia but it is widespread around other parts of the temperate world as an introduced species and a common weed. [5]
It grows in many types of habitat, including lawns and roadsides.

It is quite variable in appearance, especially across subspecies. In general, it is a rhizomatous perennial herb forming mats of branching, four-angled stems lined with lance-shaped leaves a few centimeters in length.

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.

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 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.
Stellaria longifolia is a species of flowering plant in the family Caryophyllaceae known by the common name longleaf starwort. It is native to much of the northern half of the Northern Hemisphere, occurring throughout northern Europe and North America. It grows in many types of moist habitat, including meadows, marshes, and roadsides. It is a rhizomatous perennial herb forming clumps with sprawling, branching stems which are mostly hairless except for tiny rough hairs along the edges of the squarish stem. The linear to lance-shaped leaves are up to 3.5 centimeters long and are oppositely arranged in pairs. The inflorescence bears several flowers, each on a short pedicel. The flower has five pointed green sepals each a few millimeters long. There are five white petals, each so deeply lobed it appears to be two.
Stellaria longipes is a species of flowering plant in the family Caryophyllaceae known by the common names longstalk starwort and Goldie's starwort. It has a circumpolar distribution, occurring throughout the northernmost latitudes of the Northern Hemisphere. 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. The flower has five pointed green sepals each a few millimeters long. There are five white petals each divided into two lobes, sometimes shallowly, but often so deeply there appear to be two petals.
