Platanthera tipuloides var. nipponica is
a perennial orchid species inhabiting sunny wetlands, its stems
measuring 20-40cm in height, with a single leaf. The leaves are
broadly linear, each 3-7cm long, and the bases embrace the stems.
Scaly leaves stick to the branches to be unnoticeable. The
spike-like inflorescence is with some light yellow-green flowers on
one side. Spurs are leaping up backward, measuring 1.5--1.8cm in
length. Bloom time: June-August.
