Japanese name: ツルネコノメソウ （蔓猫目草）
Scientific name: Chrysosplenium flagelliferum

[Overview]
A perennial found in wet, marshy places along streams in deciduous mountain forests.
After flowering, the stolons grow long over the ground like vines and spread in all directions, bearing leaves of the same shape as those on the stem.
A young plantlet forms at the tip of each stolon.
The leaves are of two kinds: basal leaves, and leaves arranged alternately on the flower stalks and stolons; the basal leaves have usually withered by flowering time.
The basal leaves are round, 2–3.5 cm long and 3–5 cm wide, with 7–17 rounded teeth on the margin, sparse hairs on the upper surface, and petioles 5–8 cm long.
The flower stalk is 3–15 cm tall, bears 2–3 leaves, and is almost hairless.
The stem leaves are round, 0.2–0.8 cm long and 0.3–0.9 cm wide, with 5–7 rounded teeth on the margin, and have petioles.
A cyme is produced at the tip of the flower stalk.
The inflorescence has leaf-like bracts, and the upper bracts are ovate.
The flowers are 3–6 mm across and have no petals; the calyx is green to yellowish green and spreads flat.
There are 8 erect stamens, and the anthers are yellow before they split open.
The fruit is a capsule that splits open when ripe, and many seeds show.
The seeds are ovate.
