Cultivar Registration Information


Thank you for your interest in registering a Brugmansia cultivar with the International Brugmansia and Datura Society, Inc. (iBrugs).  Registration assists with the orderly management of the ever-growing number of cultivar names world-wide, and is aimed at reducing opportunities for misuse, misapplication, duplication, loss and confusion of names.  Hence it assists the protection of breeders, growers, distributors, collectors, home gardeners, and authors from embarrassment and inconvenience caused by misnaming the plants you have worked hard to create and select. ABADS is designated in the 2009 edition of the International Code of Nomenclature for Cultivated Plants [the 2009 Code] as the official International Cultivar Registration Authority [ICRA} for Brugmansia and Datura (Solanaceae).This role was delegated to ABADS by the International Society for Horticultural Science [ISHS] in 2002. In summer of 2010, ABADS officially became the International Brugmansia and Datura Society (IBADS/iBrugs).

In accordance with the 2009 Code, acceptance of a Brugmansia cultivar name by iBrugs does not imply judgment on the distinctness of a cultivar nor its horticultural merit.  iBrugs does not therefore seek to reject applications on the basis of subjective judgments of the quality of the plant or its name.  iBrugs will only reject applications that transgress the 2009 Code or fail to meet the basic requirements of the registration process.  We do however urge self-regulation to encourage the submission for registration of only cultivars that demonstrate a real improvement over existing cultivars, or at least over those available within a particular country or region defined by quarantine barriers. Establishment of a cultivar name in perpetuity is effected by valid publication, not by registration as such. From the ISHS page, ‘How to name a new cultivar’, ‘What do I do with my new name?’

    "Publication of your new name must be in printed or similarly duplicated matter which is distributed to the general public or at least to botanical, agricultural, forestry or horticultural institutions with libraries. Newspapers, gardening or non-scientific magazines and similar publications which are not designed to last do not count as publications in this case. Publication on the World Wide Web or on CD-ROM does not count as publication since the pages are not permanent.”

iBrugs therefore undertakes to publish names of new cultivars that have been accepted into the Register, in a form that complies with the requirements for validity specified in the 2009 Code, in our quarterly journal, The Trumpeter. This is the primary role of the ICRA, which is currently iBrugs.  Please note

Understanding the term and process of "Registration":

The ICRA at iBrugs is the only entity which can officially register a Brugmansia or Datura cultivar. While the term may be loosely used, it is important to understant that unless you are completing your registration for your cultivar through the registration form within the iBrugs website, your cultivar has not been officially registered until it has been done so by yourself. Any other method of submission, including through other brugmansia websites that offer cultivar registrations, is not official and there is no guarantee your cultivar will be processed as such.  All registration reservations are provisional until they are confirmed by the ICRA for Brugmansia, IBADS/iBrugs.


International Cultivar Registration Authority (ICRA) for Brugmansia and Datura

The Official role of ICRA for Brugmansia is iBrugs.

Membership in the International Brugmansia & Datura Society  is not needed in order to be able to register Brugmansia and Datura. Registrations must be submitted through them. However they are recognized by the RHS as the registering authority for Brugmansia and Datura.

The American Brugmansia and Datura Society began the necessary steps to become the International Cultivar Registration Authority (ICRA) for Brugmansia and Datura in May 2002. In the second week of August, our formal application was presented to the Nomenclature and Cultivar Registration Commission Members of the International Society for Horticultural Science (ISHS), at their convention in Toronto.

On November 13, 2002, ABADS received a letter dated November 5, 2002, from Dr. Alan Leslie of the Royal Horticultural Society (RHS), who is the Senior Registrar, informing us that our Official position as the International Cultivar Registration Authority (ICRA) for Brugmansia and Datura has been approved! Our official position as ICRA went into effect November 2, 2002.

During the summer of 2010 the American Brugmansia and Datura Society's corporate name was officially changed to the International Brugmansia and Datura Society. This does not affect the role of ICRA in any way, and maintains that role to be the official holder of the ICRA registry.

The International Brugmansia & Datura Society is responsible to keep records of old and new Brugmansia and Datura cultivars:

"As well as recording the names, ICRAs also collect information about the cultivars themselves. Apart from recording descriptive details, collecting details of the author of the name or the breeder/raiser of the cultivar gives precision to the very meaning behind the name itself so that a plant name carries a measurable identity. The ICNCP endorses the collection and maintenance of nomenclatural standards - herbarium specimens or illustrative material against which a cultivar name may be checked for authenticity. Thus there is true meaning behind every cultivar name. The grower or purchaser of a plant which carries a cultivar name should be able to discover the supposed attributes of that plant from a truly authoritative source."

ISHS ICRA Introduction

ICRA registration does not protect the plant itself. Patents are intended to protect the plant! An ICRA is the official keeper for the official recorded names and history of each Brugmansia and Datura cultivar.

New Registered Cultivar Names are published four time a year in the International Brugmansia and Datura Society's quarterly journal, "The Trumpeter".

About the ISHS International Cultivar Registration Authorities (ICRA)

International Cultivar Registration Authorities (ICRA), whether they represent agricultural, forestry or horticultural disciplines, are appointed by the International Society for Horticultural Science (ISHS) through its Commission for Nomenclature and Cultivar Registration and are contracted to operate within the provisions of the current edition of the International Code of Nomenclature for Cultivated Plants (ICNCP). iBrugs is the only ICRA authority to register Brugmansia.

The purpose of an ICRA is to:

Promote fixity and stability in the nomenclature of the categories cultivar and groups within designated plant taxa and to produce and promote authoritative checklists and registers of all names known to have been in use in such taxa.

The primary functions of an ICRA are:

(a) To register cultivar and group names in the denomination class for which they have accepted responsibility, and to ensure their publication and establishment.

(b) To record, publish, and make otherwise available, full lists of all cultivar and Group names in that denomination class whether they are in current use or are part of the historical record so as to provide the world community with authoritative listings of names.

(c) To maintain records, in as great a detail as is practical, of the origin, characteristics and history of each cultivar and Group in that denomination class.

It is NOT the function of an ICRA:

(a) To conduct trials.

(b) To judge if one cultivar or Group is more meritorious or more useful than another.

(c) To judge distinctness of cultivars or Groups.

NOTE: Although an ICRA does not in itself conduct trials, the organization sponsoring an ICRA often does.
