Polygara japonica is
a perennial herb inhabiting sunny fields and mountains with haired
stems. The stems crawl on the ground and grow diagonally upward to
around 10-20cm in height. Leave are alternate, in an oval to
long-oblong shape, 1-3cm long, with short petioles and pointed tips.
Axils on the upper parts of the stems emerge short racemes with
purple-tinged flowers shaped like a butterfly. Sepals are 5 in
number; petaloid side-sepals are oval to oblong, 6mm long, and
purple, enhancing after the flower to 1cm, becoming green. Petals 3
are connate at the bases, and one cut itself in at the tips. Bloom
time: April-July. |
