Epipactis thunbergii is a
perennial, terrestrial orchid found in sunny, moist grasslands or
swamps, the stems standing 30-60 centimeters tall. The opposite
leaves are green and a bit hairy, on which there exist remarkable
longitudinal waves along the veins. As for flowers, the stems bear
5-10 yellow-brown flowers on the upper portion of them, each sepal
and petal measuring 1.5cm in length; they stand out in concealment
in plants around the vegetation. Shimane RDB lists this as a VU. |
