|discussion=<p>In Europe, both diploid and tetraploid cytotypes of <i>Stellaria graminea</i> 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 <i>S. longifolia</i> 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.</p><!--
--><p>The sterile overwintering shoots of <i>Stellaria graminea</i> 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 <i></i></i>var.<i><i> latifolia</i> Petermann. Usually <i>S. graminea</i> 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.</p>
