2.  Spergularia marina (L.) Griseb. ne

saltmarsh sand-spurry. Spergularia leiosperma (Kindb.) F. Schmidt; S. marina (L.) Griseb. var. leiosperma (Kindb.) Guerke; S. salina J. & K. Presl; Tissa marina (L.) Britt. • CT, MA, ME, NH, RI, VT; primarily coastal counties. Saline and brackish marshes, coastal beaches and strands, salted roadsides and edges of parking lots. This species has been collected from some interior counties (e.g., Berkshire County, MA, Washington County, VT), where it should be considered non-native. Spergularia marina has been called S. salina in recent literature, but the epithet marina has priority over salina at the rank of species (published in 1785 vs. 1819). However, application of epithet marina has been inconsistent, and some favor its rejection as an ambiguous name.

Native to North America?

Yes

Sometimes confused with

Spergularia canadensis:
flower stalks and sepals usually without hairs, stipules 1-2.8 mm long, and seeds 0.8-1.4 mm long (vs. S. marina, with flower stalks and sepals usually with glandular-hairs, stipules 2-4 mm long, and seeds 0.6-0.8 mm long).
