See text Epipactis, or helleborine, is a genus of terrestrial orchids consisting of approximately 70 species.

Their creeping, fleshy rhizomes grow offshoots, from which then emerge the 20–70 cm long stems during the next spring.

The lip is divided in a bowl-shaped hypochile, with the outer surface greenish-white and threaded with dark veins.

These orchids grow in open spaces in forests, in undergrowth, on calcareous soils and are often found in wet dune-slacks near the sea.

Epipactis gigantea is a species found in the American west, and into southern Canada, in wet areas and even streams.
