lamb's lettuce

This is 'Nodisya' or lamb's lettuce. The Japanese name 'Nodisya'
means lettuce ('disya') found in field ('No'). This is the same plant
as Rapunzel written in "Grimm's Fairy Tale". The botanical name is
Valerianella locusta.

I found this by the roadside of a rice field. You can compare the
size with that of clover... very small!
