In the spring this association is dominated by Caltha PALUSTRis and Spathema foetida with, as secondary species: Senecio aureus - Cardaminc rhomhoidea Ranunculus septentrionalis Eanunenlus sceleratus During the summer, Saururus cernuus (fig. 9) dominates the association, while in the autumn its place is taken by Polygonum ari- POLiUM, with which are a large number of species in greater or less abundance, including the following: Chry-osplenium americanum Alisma suhcordatum Carex sp. PentJiorum sedoides Isnardia palustris Bidens connata Bidens aristata Bidens cernva 7ohelia cardinalis Lohelia syphilitica Lillium canadense Solidago pntnla Phlox maculata Blepharit/Jottis Uicera On one side this swamp is contiguous with a wooded hillside bear- ing the usual forest of the coves. At the meeting place the two associa- tions are sharply demarked by the character of the soil. There is no sign of the encroachment of one association on the other and no tension zone between Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Griggs, Robert F.
