Paronychia fastigiata (Raf.) Fern. - Cluster-stemmed Nail-wort, Hairy Forked Nailwort
This species is also reported from unspecified localities in Suffolk Co., NY.
This species is possibly more common than the map would indicate. Due to its diminutive stature and un-showy flowers, it might be overlooked, and therefore under-reported/collected.
