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