Epipactis, or helleborine, is a genus of terrestrial orchids consisting of approximately 70 species. This genus is abbreviated as Epcts in horticultural trade.

Neottieae is an orchid tribe in the subfamily Epidendroideae. It contains six genera and over 200 species distributed mainly in temperate and subtropical zones of the northern hemisphere. All its members are terrestrial plants, hinting at an early branching with Epidendroideae which is largely an epiphytic group. Neottieae is likely to be the result of a single temperate radiation of epidendroids, although it appears that some lineages in this tribe have crept back into the tropics.
