Epipactis helleborine is a distinctive species which is only likely to be mistaken in the wild for the native Epipactis gigantea. A number of key characteristics separate these two species. The flowers of E. gigantea are large, the sepals and petals are 12-20 mm long, and the lips are 14-20 mm long and grooved to the tip (Douglas et al. 2001). The flowers of E. helleborine are smaller, the sepals and petals are 8-13 mm long, and the lips are 10-12 mm long and more or less flat above the middle (Douglas et al. 2001).
