A common terrestrial orchid (illustration) that produces small, inconspicuous yellow-green flowers in midsummer. The whole plant has a pleasant fragrance. The rhizome and tuberous roots are elongated and run horizontally, not very different from the roots of normal plants. The flower stalk is 20-40 cm long. There are usually two leaves near the base, narrowly obovate and 6-15 cm long, with the upper leaves being extremely small. In July and August, 10-20 flowers are produced, somewhat densely spaced. The flowers are yellow-green and about 4 mm in diameter. The dorsal sepals and petals are helmet-shaped, and the lateral sepals open. The lip has small lateral lobes at the base.
