Read about Cephalanthera in the Standard Cyclopedia of Horticulture

Cephalanthera (Greek for head and anther). Orchidaceae. About 10 species of small temperate-region terrestrial orchids, allied to Epipactis and Pogonia. Some of them are western N. American, and others are European. Sepals 3; petals small, ovate; lip saccate: lvs. (sometimes wanting) lanceolate or oblong: fls. mostly small (sometimes showy), in an open spike. The species are scarcely known in cult., but 2 Japanese species have been offered by importers. These are E. falcate Blume, yellow, and E. erecta, Blume, white.

Cephalanthera is a genus of, mostly, terrestrial orchids. Members of this genus have rhizomes rather than tubers. About 15 species are currently recognised, several of them common in Europe, for example the Sword-leaved Helleborine C. longifolia. Most others are native to Asia, ranging from the Caucasus, e.g. C. caucasica, to Japan, e.g. the Bamboo-leaved Silver Orchid C. longibracteata. The Chinese species C. gracilis was only described in 2002. The only species found in North America is the Phantom Orchid or Snow Orchid C. austiniae. Ecologically, this species is partially myco-heterotrophic. Some of the Eurasian species hybridise.

Several of the European species have common names including the word "helleborine", but this name does not correspond to any modern taxon, and orchids in other genera are also called helleborines. In addition to those listed here, very large numbers of other specific names will be found in the older literature, but these are almost all synonyms for the best known species such as C. longifolia or C. damasonium, the European White Helleborine.
