Have you created a new Passiflora hybrid you are very excited about? Do you want to be sure that your chosen name will live for all perpetuity at the international level? This is where you make it happen.
Please read through all of the following information very carefully before continuing to the registration website.
The Passiflora Society International (PSI) has been designated as the International Cultivar Registration Authority (ICRA) by the International Society for Horticultural Sciences (ISHS at http://www.ishs.org/sci/icra.htm) with sponsorship from the Royal Horticultural Society (RHS at http://www.rhs.org.uk). The registrar appointed by PSI is responsible for reviewing, editing, and accepting or rejecting cultivar and hybrid registrations based on the International Code for the Nomenclature of Cultivated Plants (ICNCP: http://www.ishs.org/sci/icracpco.htm), most recently updated in 2009. The registrar appointed by the PSI is the final arbiter of any registration issue in genus Passiflora.
The job of the registrar is to ensure that the PSI follows the ICNCP, to ensure stability of names, to create a list of plants in cultivation, to record acceptable names of new cultivars, and to elicit and provide descriptions of those new cultivars. It is not the job of the registrar to examine individual plants and determine their “distinctness” or commercial viability. However, certain crosses (e.g. P. x violacea x P. caerulea), which have been made hundreds of times may not be accepted for registration given the low likelihood that another version of the same cross would be distinct.
In the genus Passiflora, we currently only register cultivars, as opposed to other genera where one may also register a grex or group. The term cultivar was introduced in 1961 to designate a “cultivated variety” that retains its distinguishing features when reproduced. While most Passiflora cultivars are hybrids, new cultivars may also be attained by genetic alterations of existing plants (e.g. altering gene ploidy), propagation of sports, or human selections from nature of plants with specific, stable traits. In the recent past, most new cultivars were F1 hybrids, but complex hybrids including three or more species, have become more commonplace.
The PSI has established a website for submission of new registrations. The interface requires certain fields be completed for submission, and these are the minimum that will be accepted for registration. The intent in allowing a registration to be submitted with the minimum amount of information is to encourage the novice gardener to submit registrations. The more experienced and/or ambitious registrant is encouraged to complete as many of the descriptive fields as possible in order to preserve a detailed record of the cultivar/hybrid. Use of this interface is mandatory, and any questions or problems may be directed to the registrar who may, in turn, consult with the officers of the PSI.
A valid email address must be submitted. If the registrar needs to contact the person registering a hybrid (registrant) and cannot, the registration will be immediately rejected.
The PSI will, in turn, publish new registrations in the format of its choosing.
If the registrant should wish to preserve a herbarium specimen to constitute a nomenclatural standard of the cultivar, please contact the registrar who will facilitate this process via the Royal Horticultural Society and the herbarium at Wisely.
Rules of Registration:
The ICNCP dictates that the name of cultivars/hybrids consist of two parts. The first is the name of the genus (Passiflora in this case, or simply abbreviated “P.”). The second is the part traditionally thought of as the “name” of the cultivar/hybrid, the epithet.
The epithet is subject to extensive rules, many of which are intended to avoid any confusion with other existing epithets. The simple rules include that the epithet:
- is written between single quotation marks (inverted commas).
- is not italicized.
- is written with the first letters in all words are capitalized (e.g. P. ‘Betty Myles Young’); except in the case that a word follows a hyphen or is a conjunction or preposition (e.g. P. ‘Raspberries and Cream’, P ‘Star of Bristol’, P. ‘Stella de Cremona’).
- is in a modern language (not Latin, unless the Latin word is in contemporary usage).
- is no more than 30 characters (excluding spaces).
- may not only be made up of existing words; they may be of novel invention.
- may include punctuation marks including the apostrophe (‘), the comma (,), up to two non-adjacent exclamation marks (!), the period (.), the hyphen (-), the forward slash (/) and backward slash (\). Additionally, codes may be acceptable but only up to four alternations between numbers and letters are allowed (e.g. P. ‘AB12CD34’ would be allowed while P. ‘A1B2C3’ would not).
Epithets may not have certain characteristics. These include that the epithet:
- may not be made up of one character or numeral, or one character or numeral accompanied by a punctuation mark.
- may not contain the words “form” or “variety” or translations thereof.
- may not contain the words “cultivar”,“grex”, “group”, “hybrid”, “maintenance”, “mixture”, “selection”, “series”, “sport”, “strain”, “improved”, or “transformed”.
- may not include punctuation marks other than the above (e.g. “?” is not acceptable).
- may not include fractions when written with numerals, but may be spelled out (“1/2” is not acceptable, but “One Half” is).
- may not be the name of another genus if such naming could cause confusion.
- may not be too similar in character to an existing name (e.g. Since P. ‘Tereza’ already exists, an application for registration of the epithet P. ‘Teresa’ would be rejected).
- may not exaggerate the characteristics of a plant and may subsequently be replaced by cultivars that more aptly fit the description (e.g. P. ‘Longest Peduncle Ever’).
- may not be purely descriptive (e.g. P. ‘White’ could describe many Passiflora cultivars, and therefore would not be accepted).
- may not contain descriptors that are misleading with respect to the cultivar (e.g. a plant with pure white flowers with straight filaments should not be named P. ‘Wavy Black’).
- may not give a false impression that a cultivar is related to cultivars to which it is not related, or that falsely associates it with a person or institution (e.g. a plant not from Strybing Arboretum should not be named P. ‘Strybing Green’ and a plant not bred by Ron Boender should not be called P. ‘Boender’s Delight’—unless of course the individual or institution supported the epithet).
- may not contain the name of a living person without the assent of that living person.
There are also certain characteristics suggested for epithets. Recommendations include that epithets:
- should be as short and simple as possible.
- should not contain words that would be difficult to spell or pronounce.
- should not contain terms likely to be found in the marketplace as they may cause confusion at the place a plant is being sold (e.g. terms like “container grown”, “ten dollars”, “bonsai”, and “two-litre” should generally be avoided, whereas “million-dollar” is unlikely to cause confusion at the marketplace).
There is a subjective line in the ICNCP, Recommendation 21K, which states “A cultivar name should not be published if its epithet may cause offence.” As not all offenses are predictable, this rule shall be taken on a case-by-case basis.
Additional Recommendations for Registration:
As it is best that registered plants be preserved and have complete records, it is strongly recommended that the registrant:
- grow the new cultivar for at least a full year after first bloom to determine vigor, floriferousness, temperature tolerances, fruit characteristics, et cetera.
- distribute the new cultivar to a minimum of 3 people via asexual propagation.
- enter as many measurements and as much information as possible, as this registration record is permanent and unalterable.
- list the parentage used to create the hybrid.
- if the hybrid was a joint effort, name the pollen donor, breeder, raiser, introducer, or anyone else that participated in the process.
If the chosen name or entire registration is rejected by the registrar, the registrant will have the opportunity to challenge the rejection if he/she believes it to be unjust. The complete written appeal arguing why the hybrid properly fits within the guidelines presented herein will be reviewed by no less than three (3) PSI officers, who will confer with the registrar expressing their opinion of whether or not the hybrid should be registered. The registrar may at that time reverse his/her decision or agree with the initial determination. The outcome of the appeal will be final.
By submitting a hybrid registration, the registrant grants an immediate, irrevocable, perpetual, worldwide non-exclusive license to the PSI, to reproduce, distribute, display and create derivative works of the photos, (along with a name credit), in connection with and in promotion of the PSI. The PSI will not be required to pay any consideration or seek any additional approval in connection with such use.
