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. 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.
