Spergularia maritima (All.) Chiov. - Middle-size Sandspurry, Greater Sea-spurrey
= Spergularia media (L.) C. Presl ex Griseb.
This species is also reported from unspecified localities in Nassau and Suffolk Cos., NY.
This halophytic species is possibly more common than the map would indicate (especially along salted highway margins and the coast). Due to its diminutive stature, it might be overlooked, and therefore under-reported/collected.
