'''''Epipactis''''' [[Johann Gottfried Zinn|Zinn]], 1757, or '''Helleborine''' is a genus of [[orchid]]s comprised of approximately 70 terrestrial species.
They occur in temperate and subtropical climates of [[The Americas|America]], [[Asia]], and [[Europe]]. These orchids grow in open spaces in forests, in undergrowth, on calcareous soils and are often found in wet dune-slacks near the sea. The only original American species is Giant Helleborine (''Epipactis gigantea''). One species from Europe, Broad-leaved Helleborine (''Epipactis helleborine''), is invasive in [[North America]]. Most species are protected.
[[Image:Epipactis-gigantea1web.jpg|thumb|left|Giant Helleborine<br />(''Epipactis gigantea'')]]
Most of these hardy orchids grow in a wet environment. The Marsh helleborine (''Epipactis palustris'') is the only European orchid able to survive in a flooded habitat. ''Epipactis gigantea'' is a species found in the American west, and into southern [[Canada]], in wet areas and even streams. It can grow to a height of 1 m. But ''Epipactis helleborine'' grows in more diverse habitats, from sheltered sandy beaches to open spaces in deciduous or coniferous forests, to moist soils. And there are other exceptions.
They all strongly depend on their [[symbiosis]] with their [[hypha|hyphal threads]]. Some species therefore have reduced leaves and need little chlorophyll. Violet Helleborine (''Epipactis viridiflora'') can even do without chlorophyll. These forms can be recognized by their purple instead of violet flowers.
Their creeping, fleshy [[rhizomes]] grow offshoots, from which then emerge the 20-70 cm long stems during the next spring.
There are four to eight alternate, lanceolate [[Leaf|leaves]], that grow progressively shorter near the top. The margins are entire, the top is acute. Species with less [[chlorophyll]] have blue-purple leaves.
Their bilaterally symmetrical colorful [[flower]]s grow from a terminal raceme. The three [[sepal]]s and the two lateral [[petal]]s are ovate and acuminate. Their color can vary from greenish-white to violet and purple.
The [[labellum|lip]] is divided in a bowl-shaped hypochile, with the outer surface greenish-white and threaded with dark veins. The wavy, snowwhite epichile is fan-shaped.
The [[ovary (plants)|ovary]] is inferior. It produces a dry [[capsule (fruit)|capsule]] with countless minute [[seed]]s.
