Cephalanthera, abbreviated Ceph in horticultural trade, is a genus of mostly terrestrial orchids.

About 15 species are currently recognized, most of them native to Europe and Asia.

[1][2] The only species found in the wild in North America is Cephalanthera austiniae, the phantom orchid or snow orchid.

Several of the European species have common names including the word "helleborine", though 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.
