Japanese name: ノチドメ（野血止） Scientific name:Hydrocotyle maritima
[Overview]
A perennial growing in slightly moist places such as fields and paddy ridges.
The stem is hairless, branches, creeps along the ground, and spreads by producing roots from the nodes.
The upper part of the stem and the branches rise obliquely.
The leaves are alternate, reniform-orbicular, 1–3 cm in diameter, 5-lobed, with the lobes cut to about 1/2–2/3 of the leaf radius.
There are sparse long hairs on the veins on both sides of the leaf, and the margin has blunt serrations.
The leaves have petioles.
One globular umbel emerges opposite a leaf, bearing 5 to 10-odd flowers.
The flower stalk is usually shorter than the petiole, so the flowers bloom lower than the leaves.
The flowers are very small, pale green, star-shaped 5-petaled flowers with 5 stamens and 2 styles.
The fruit is a schizocarp with the styles remaining.
