Polygara
japonica is a perennial herb that inhabits sunny fields
and mountains, characterized by its hairy stems. The stems crawl
along the ground and grow diagonally upward to a height of
around 10-20 cm. Leaves are alternate, oval to oblong, 1- 3 cm
long, with short petioles and pointed tips. Axils on the upper
parts of the stems bear short racemes of purple-tinged flowers
shaped like a butterfly. Sepals are 5; petaloid side-sepals are
oval to oblong, 6mm long, and purple, darkening after the flower
to 1cm and becoming green. Petals 3 are connate at the base, and
one is cut at the tips. Bloom time: April-July.
