Neither L innaeus, Ha ller, nor Scopoli, mention this plant in their refpeftive Floras. O eder figures
it in the Flora Danica: the plant he gives us appears as if it had grown in water of fome depth : with us
it is raoft commonly found fpreading widely on the mud of flow (hallow rivulets, especially where the foil
is fandy.
It flowers during mod o f the fummer months.
We fometimes meet with the leaves having a dark fpot in the middle of each, and in fome fituations the
blolfoms are much larger than in others.
