Epipactis gigantea Douglas ex Hook.[FNA26, HC, HC2]
giant helleborine

Publication: Fl. Bor.-Amer. 2: 202, plate 202. 1839.

Origin: Native

selected vouchers: WTU

Notes: FNA26: "Two very distinct color forms of this species have been published: Epipactis gigantea forma rubrifolia P. M. Brown, with deep red stems and leaves, and E. gigantea forma citrina P. M. Brown, with lemon-yellow flowers. Both are known from California.

The occurrence of this wide-ranging species in India and Tibet is based on Epipactis royaleana Lindley ex Royle being given as a synonym in a study of the Monocotyledoneae of Karakorum (W. B. Dickoré 1995) and an embryologic study (S. P. Vij et al. 1999)."
