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