[Overview]
A perennial found in wetlands along streams.
The stolons creep along the ground and are hairless except at the leaf axils.
The leaves are of two kinds: basal leaves, and leaves borne on the flower stalks and stolons; the basal leaves persist even during the flowering season.
The leaves are round to elliptic with conspicuous veins and blunt teeth on the margin.
The flower stalk bears no leaves, or bears one opposite pair of simple leaves.
The stolons extend after flowering.
A cyme is produced at the tip of the flower stalk.
The inflorescence has leaf-like bracts that are ovate to oblong-elliptic, and the bracts turn yellow at flowering time.
The flowers have no petals.
There are 8 stamens, 1.5–2 mm long, shorter than the calyx.
The style is also 0.8–1 mm long and shorter than the calyx.
The calyx is dark reddish brown and erect.
The fruit is a capsule that splits open when ripe, and the seeds show.
The seeds are elliptic, densely covered with club-shaped projections.
