Agalinis acuta is an annual hemiparasitic plant native to Maryland, Massachusetts, Rhode Island, Connecticut, and Long Island, New York. Common names include sandplain gerardia and sandplain false foxglove. It is one of about 70 species that comprise genus Agalinis. It currently resides within the family Orobanchaceae, but historically was aligned with members of the Scrophulariaceae. This was one of several re-alignments that were the consequence of the disintegration of the Scrophulariaceae as the result of conclusions based on molecular phylogeny data from the chloroplast genome. While historically regarded as a separate species, molecular phylogenetic data indicates that Agalinis acuta should be consolidated as part of the species Agalinis decemloba.
Minuartia groenlandica, the Greenland stitchwort or mountain stitchwort, Appalachian stitchwort, mountain sandwort, smooth mountain sandwort, and smooth sandwort is a rare perennial which grows low to the ground in clumps linked together at the bottom. It has three to five pairs of leaves in a linear opposite pattern along the length of the slender stem. The main stem breaks into one to thirty cymes which each flower separately.

This perennial grass grows decumbent or erect to a maximum height near 40 centimeters, often remaining much smaller, especially in harsh habitat. It may root at stem nodes which become buried in wet substrate. The inflorescence is a dense or open array of branches bearing spikelets.

Veronica anagallis-aquatica is a species of flowering plant in the family Plantaginaceae known by the common names water speedwell, blue water-speedwell,brook pimpernel, and sessile water-speedwell. It is also listed as Veronica catenata. Its true native range is not clear, but the plant is present on most continents, and in most places it is probably naturalized. It occurs in many types of moist and wet habitat, and it is semi-aquatic, often growing in shallow water along streambanks, in ponds, and in other wetland environments. It is a rhizomatous perennial herb with stems growing 10 centimeters to about a meter in maximum length. It may be decumbent, the stem spreading along the ground and rooting where it touches moist substrate, or erect in form. The oppositely arranged leaves are green, smooth-edged or toothed, and sometimes clasping the stem where the leaf pairs meet at the bases. The inflorescence is a raceme of many flowers arising from the leaf axils. Each flower is borne on a short, curving pedicel. The flower corolla is up to a centimeter wide with four lobes, the upper lobe being widest. It is blue, lavender, or violet with purple lines near the base of each lobe. At the center are two small protruding stamens.
