These latter include: Sphagnum sp., Drepanocladus fluitans, Dulichium arundinaceum, Iris versicolor, Potentilla palustris, Hypericum virginicum, Sium cicutaefolium, and Lysimachia tcrrestris. As along sandy shores, the sweet gale and alder fringe the shore at high water mark. Along sandy shores there is little evidence of succession, but along muddy shores there is a tendency for swamps to develop. The association-types of permanent ponds.—Small ponds (Figs. 26. 42) may differ little from lakes in the character of.
