Drosera (sundew)
Mount Desert Island's two species of sundews can be distinguished from each other by their leaves. Drosera intermedia leaves have a blade that is longer than wide, and the blade of D. rotundifolia leaves is more or less round or even a bit wider than long.
Drosera intermedia (spatulate-leaved sundew) - [information to be added]

Although a small plant, they can be present in quantity, enough to give a reddish hue to a substantial area.
Drosera rotundifolia (round-leaved sundew) leaves (petiole plus blade) are approximately the same length as those of D. intermedia. The picture below, taken in mid-May, is of young leaves, which are, of course, much smaller than full-grown ones.
