Ditchgrasses are aquatic species, rooting in mud in fresh or brackish
waters. Their perfect flowers are borne on long tenuous and coiled
peduncles from the axils of upper leaves. Arranged in short spikes,
each flower is initially concealed within a spathe. Stamens are two.
Leaves are alternate or opposite, each with a single midrib. One
species is found in Nova Scotia. Photograph by Alex Wilson.
