This association forms a crescent-shaped area at the base of the cemetery bluff, commencing with the seepage springs (fig. 2 and map) and reaching stream-ward as far as the water sedge. It is here 700 feet long and 200 feet wide, containing the following species listed in order of their relative abundance: Scirpus americanus, Carex filijormis, Koellia flexuosa, Lysimachia quadrifolia, Campanula aparinoides, Lobelia Kalmii, Aster junceus, Parnassia caroliniana, Rynchospora alba, Gerardia paupercula, Solidago Riddellii, Sarracenia purpurea, Larex laricina (once abundant, but now removed for firewood).

A sharp line of separation occurs between it and neighboring societies. As a whole it may be said that the vegetation is the most distinct of all those studied. With but two exceptions all species are perennials, and a certain likeness of form characterizes the members, as if mutually adapted to xerophytic conditions, causing the vegetation to stand out in contrast with the neighboring broad-leaved hydrophytes. Regarding this group of plant societies the following points are to be noted. 1.
