Caltha
palustris var. nipponica, a perennial herb with a 30-
50 cm height, inhabits wetlands or water's edges. Leaves are
orbicular, 5-10 cm in size, with shallow serrations on the
margins. On-stem leaves are small; the stem tops and upper axils
bear bright yellow flowers, about 2cm in diameter. The flowers
lack petals, which makes the sepals look like petals. The sepals
are 5-6 in number. Many stamens surround the pistils. Bloom
time: May-July.
