Cucubalus baccifer var. japonica, a
perennial associated with an alien, has grown wild in fields and
mountains in Japan from time immemorial. Vine-like stems branch well
and grows to more than one meter, and leaves are 2-5cm, in the shape
of an oval. Flowers bloom facing sideways or downwards, with
conspicuous hemispherical calyxes; petals are white, with limbs
cleft in two. Capsules are almost spherical, become flesh bacca and
dehisce not. Bloom time: June-August.
