The Aril Society International
Official Checklist


Covering Cultivars Registered

From 1800 Through 2013
Joseph G. Stringham, Editor
In this nonillustrated edition, registered and introduced aril and arilbred irises are presented without photographs. There are appendices at the end of the alphabetical section, listing cultivars appearing in the pedigree of some of the irises in the checklist that are difficult to find elsewhere. These irises were either not registered or their registration became obsolete. For the purpose of this checklist, registered cultivars are listed in capital letters, e. g., ALADDIN’S GEM; any unregistered names are listed in lower case, e. g., Vera. Garden names are listed in quotation marks, e. g., ‘Dirty Dora’. For ease of finding names in the main alphabetical section of the list, entries are set in bold characters. Likewise, in pedigrees the pod and pollen parent are separated by a boldface capital X. For example, ALADDIN’S GEM: (AR8701: … X Brownett). We hope this will make it easier to decipher some of the long and complicated pedigrees of some cultivars.
Our special thanks to Tom Waters who has supplied chromosome information to many more of the cultivars in this year’s Checklist. If any errors or omissions are found please contact us. Thank you.

Each entry gives the following information, as applicable:
1) Name

2) Classification

3) Hybridizer

4) Registration date: R = Registration

BRS = Before Registration System

5) Seedling #, Original Classification Code, Height, Season

6) Description

7) Parentage

8) Synonyms

9) Introduction data

10) Chromosome information and fertility observations

Several different classification systems have been used in the past. In this version of the checklist, every attempt has been made to assign a modern, appropriate classification code to each cultivar.
Our solution has been to include in the main list only those arilbreds that qualify under the chromosome complement system: i. e., those having one-quarter or more aril complement. Varieties with less than one-quarter aril complement which were once considered arilbreds but no longer qualify are placed in an appendix. Also placed in an appendix are irises not registered as arilbreds but may contain one quarter aril complement.

In 1995, the Aril Society passed a resolution adopting the classification system described by Brian Mathew in The Iris, which was published in 1981 and revised in 1989. This resolution also defines aril species as those in the oncocyclus and regelia sections of the Subgenus Iris, Genus Iris. Aril irises include not only these individual species and their hybrids, but also any advanced-generation descendant that has only aril ancestry.


Members of the oncocyclus section of bearded irises are characterized by one bloom to the stem. This includes selected clones that have been registered or introduced as named varieties; e. g., I. susiana, I. gatesii, I. paradoxa, and Real Ebony (selected clone of I. nigricans).


A hybrid involving only oncocyclus, which may result from a cross involving oncocyclus species, oncocyclus hybrids, or both, e. g., Ravid and Galilee Prince.


Members of the regelia section of bearded irises are characterized by normally producing as many as two blooms to the stalk. This includes selected clones that have been registered or introduced as named varieties, e. g., I. korolkowii, I. stolonifera, I. hoogiana, and Decorated Giant (selected clone of I. stolonifera).


A hybrid involving only regelia, which results from a cross involving regelia species, regelia hybrids or both, e. g., Vera.


A hybrid involving regelia and oncocyclus, predominately regelia in phenotype, typically resulting from a cross between

1. a regelia species or regelia hybrid and an oncocyclus species or oncocyclus hybrid,

2. a regeliocyclus and a regelia species or a regelia hybrid,

3. two regeliocycli, or

4. an oncogelia and a regelia species or a regelia hybrid.

For example, Andromache and Dunshanbe


A hybrid involving oncocyclus and regelia, predominately oncocyclus in phenotype, resulting from a cross between

1. an oncocyclus or oncocyclus hybrid and a regeliocyclus,

2. two oncogelias, or

3. an oncogelia and an oncocyclus species or oncocyclus hybrid.

For example, Purple Sequin, Judean Magic, and Moon Over Shiraz.



Arilbred irises are defined by the resolution adopted in 1995 as hybrid irises combining genetic characteristics of the aril irises and the eupogon irises. To be recognized as an arilbred and be eligible for awards by the Aril Society International, an iris must meet two separate criteria:

1. Arilbreds must contain one-quarter or more aril complement. This is determined according to the chromosome set system that was adopted in 1990 for defining aril content. The classification code (list and chart below) indicates not only what type of ancestry is involved but also the approximate amount.
Arilbreds are divided into three sub-classes: oncogeliabred, oncobred, and regeliabred. Irises in each of these sub-classes are further divided by aril chromosome complement. The majority of modern arilbreds are oncogeliabreds.

A hybrid containing any combination of oncocyclus and regelia and other eupogon irises, e. g., Oyez and Persian Padishah.


A hybrid containing both, and only, oncocyclus and eupogon irises, e. g., Opals for Ethel, Jeweled Veil, and Prairie Thunder.


A hybrid containing both, and only, regelia and eupogon irises, e. g., Miss Martha and Genetic Artist.

2. Arilbreds must exhibit at least two aril flower characteristics. The recognizable aril

flower characteristics include:

Regelia Type

1. Elongated standards or falls as in I. korolkowii.

2. Linear beards and beards on standards as well as the falls.

3. Conspicuous veining.

  1. A prominent V-shaped spot in contrasting color

Onco Type

5. Broadly domed and reflexed standards as in I. gatesii.

6. Ruffled and reflexed standards as in I. lortetii.

7. Accentuated globular form as in I. susiana.

8. Extremely broad falls.

9. Well recurved falls.

10. Thick, heavy, or broadly diffuse beards as in I. susiana or I. gatesii.

11. Exaggerated styles as in I. bismarckiana and I. iberica.

12. A definable signal spot at the end of the beard.

13. Flaring and lanceolate falls as in I. acutiloba.

14. Narrow and flaring falls as in I. paradoxa.

15. Linear beards as in I. meda and beards on standards as well as the falls.

BRS For cultivars introduced Before the Registration System was established.

DIS Disenrolled Cultivars. Those which qualified as arils or arilbreds under an earlier

system but do not meet today’s standards.

IN Ineligible Cultivars. Those that have never been elibible for awards as arils or

arilbreds, usually because they were registered in another category, but which have

enough aril ancestry to be of interest to hybridizers.

NR For cultivars introduced after the system was in place but Not Registered.


In July 1997, Tom Tadfor Little (now Tom Waters) produced A Checklist of Arilbred Dwarf and Medians through 1996. In this checklist, he employed an alphabetic notation for the chromosome configuration of arilbreds. A brief summary of this notation is given here:

A represents a set of 10 or 11 chromosomes from an aril (oncocyclus or regelia) species.

P represents a set of 8 chromosomes from Iris pumila.

T represents a set of 12 chromosomes from a bearded iris (usually TB, but may also be I. aphylla, I. reichenbachii, etc.)
Parentheses indicates a set that may or may not be present; a question mark indicates a set of unknown type.
In the absence of a chromosome count, the chromosome configuration is inferred from the parentage and (in some cases) breeding behavior.
In this notation, the fertile families of aril and arilbred irises have chromosome configurations of AA (diploid arils), AAAA (tetraploid arils), AAPP (amphidiploid-like aril-pumila hybrids) and AATT (amphidiploid-like arilbreds, such as the C. G. White fertile arilbreds and their descendants). All other configurations are expected to have limited fertility at best. These include the "Mohr type" quarterbreds (ATTT), the OGB+ triploids (AAT), arilbred medians from SDB x AB crosses (APTT), and arilbred dwarfs from SDB x aril crosses (APT).
PP indicates an irises that has some demonstrated fertility as a pollen parent; SP indicates one that has some demonstrated fertility as a seed parent.

The following listing is a compilation of aril species and variants (forms) that have appeared in literature during the last 100 years. Although reasonably comprehensive, the list is not complete. Many that have been designated as "species" by some authorities have been referenced as "varieties" by others. Some names are synonymous, some purely erroneous, and some are simply misspellings and alterations. A great deal of work needs to be done to clarify the species designations. For further information on aril species, please consult the Species Iris Group of North America SIGNA Checklist or Robert Pries, e-mail address:


The range of the oncocyclus species extends from the Negev desert of southern Israel and Jordan northward into Turkey, northern Iraq and Iran, and eastward into the Caucasus Mountains.

This edition supersedes previous versions of the ASI Official Checklist & Addenda. The ASI sources were based primarily on information published in the American Iris Society Decennial Checklists and their annual Registration & Introduction booklets. Additional sources include the British Iris Society Yearbooks, ASI yearbooks, earlier ASI checklists, the Historic Iris Preservation Society and other authoritative writings. Some photos of unregistered arils and arilbreds known to have been in commerce and used in hybridizing follow the Alphabetical List, under Unregistered Arils and Arilbreds.
