JARS v46n3 - American Rhododendron Society Plant Registry

American Rhododendron Society Plant Registry

Beginning with this issue, additions to the Register will be published with complete descriptions on a current basis rather than annually as during the past four years.

The following rhododendron and azalea names were processed through the North American registrar during the period February 1, 1992 to May 1, 1992. They have been approved and added to the International Rhododendron Register by the Royal Horticultural Society which serves as the International Registration Authority for the genus Rhododendron .

Color designations included in the plant descriptions refer to the RHS Colour Chart (1966, 1986 editions) unless noted otherwise. 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 when possible.

Species names are based on the RHS's horticulturally modified version of the Cullen and Chamberlain revision of the Balfourian Series classification. Equivalent former and present names are listed in An Alphabetical Checklist of Rhododendron Species (RHS, 1981), and in The Rhododendron Handbook (RHS, 1980).

Parents of a plant are reported 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 unacceptable because of conflict with recommendations of the International Code of Nomenclature for Cultivated Plants - 1980 , or because the name was previously registered for a different clone.

In order to avoid potential confusion, growers are reminded to register names before publishing them or distributing plants. There is no fee for registration.

Questions concerning name registration, the availability of particular names, and requests for forms should be directed to the Registrar, Jay W. Murray, Colts Neck, NJ.
