American Rhododendron Society Plant Registry
Jay W Murray, Registrar ARS Plant Names
Colts Neck, New Jersey
The Royal Horticultural Society is the International Registration Authority for the genus
Rhododendron
. The ARS, serving as North American representative to the RHS, screens names to determine whether they conform to the recommendations published in the
International Code of Nomenclature for Cultivated Plants - 1980
, and whether they are available for use. The ARS also prepares registration applications in the form required by the RHS, forwards certificates to registrants, publishes plant names and descriptions, and maintains permanent registration records.
The following list includes rhododendron and azalea names registered by the RHS, and received by the ARS during the period February 16, 1990 through February 15, 1991.
In the descriptions, most of the color designations refer to the RHS Colour Chart (1966, 1986 editions); accompanying color names are those published in
A Contribution toward Standardization of Color Names in Horticulture
, R D Huse and K L Kelly, edited by D H Voss (ARS, 1984). Colors measured by other systems are reported as received, along with equivalent RHS color numbers.
Parents of a plant are listed in the conventional order: (seed parent x pollen parent). The terms glabrous and hairless have been used interchangeably, as have the terms bullate and wrinkled. Indumentum refers to all hair types found on leaves, including scales and glands.
Names listed as synonyms are those used for a particular clone prior to registration, but rejected because of conflict with recommendations of the
Nomenclature Code
, or because the name has already been registered for a different clone. Growers carrying plants under a synonym name are encouraged to update to the registered name.
Species names are based on the RHS's horticulturally modified version of the Cullen and Chamberlain revision of the Balfourian Series classification system. Equivalent former and present names are listed in
An Alphabetical Checklist of Rhododendron Species
(RHS, 1981), and in
The Rhododendron Handbook
(RHS, 1980).
