In Europe, both diploid and tetraploid cytotypes of
Stellaria graminea occur with occasional triploid hybrids. Only the tetraploid form has been found in North America, except for a triploid colony in Newfoundland. This species is often confused with
S. longifolia but differs in its stems, which are very angular, glabrous, and not scabrid; the narrowly triangular leaves on the flowering stems; the smooth leaf margins; the stiff, triangular, prominently 3-veined sepals; and the larger, rugulose seeds.
The sterile overwintering shoots of Stellaria graminea have broader elliptic to elliptic-lanceolate leaf blades measuring 5-15 × 1.5-4 mm. They are broadest near the middle. This state of the plant has been named var. latifolia Petermann. Usually S. graminea has perfect flowers but occasionally plants that are entirely staminate-sterile are encountered. The flowers in these are partially fertile depending on the occurrence of cross- pollination.

Stellaria graminea
provided by wikipedia EN
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]
Description
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]
Distribution
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]
Habitat
It grows in many types of habitat, including lawns and roadsides.
