Cypripedium hybrids
Artificial orchid hybrids are registered by the Royal Horticultural Society. Hybrids are registered and named by the person who flowers the plant and first submits an application for registration. Note that the RHS also lists some synonyms in their database. In the database these are not listed as synonyms but the RHS plans to have the database call these out by mid-2007. For example, Cypripedium Yezo is the official name of the hybrid of Cypripedium macranthos and Cypripedium yatabeanum; another name seen in the literature for the same cross is Cypripedium Sandra Maier. This name was not registered but is listed as a synonym since it has been used in the literature.
The person who makes a given hybrid is referred to as the originator. Natural hybrids are here referred to with the letter "x" in front of the specific epithet and the author of the paper in which the natural hybrid was first described is indicated.
Hybrids listed with ( ) around them are names that have been associated with the specific hybrid in the literature or web sites but which do not appear in the RHS Orchid Parentage January 2007 listing. To search the current RHS list of Cypripedium hybrids, enter Cypripedium into both of the parent genus boxes.
The offspring of a specific cross are all referred to as belonging to the same grex. Thus, all Cypripedium Gisela, for example, are offspring of a cross between any Cypripedium parviflorum and any Cypripedium macranthos. Some propagators would like to distinguish the offspring of specific parent plants that were used for a specific cross. Some of those results are listed here: for example, Cypripedium Boots grex Christopher refers to all the offspring of the specific Boots cross reported by Peter Corkhill in 2006.
Finally, specific plants that have resulted from a given species or cross may receive awards for particular merit from a recognized judging body such as the American Orchid Society. These specific plants may then be named by the exhibitor to indicate that they were awarded. These results are not listed in this table.
We also have a table that allows you to see all the hybrids organized by parentage rather than hybrid name. That list has additional hybrids that have been reported but for which we do not know the name.
