Iris relicta is a plant species within the genus Iris, and it belongs to the subgenus Iris as well. This rare rhizomatous perennial originates from the mountains of Italy. It is of medium size, bearing purple flowers adorned with white beards. While it is seldom cultivated as an ornamental plant in temperate regions, its history has been perplexing. Initially mistaken as a variety of Iris germanica, it was later recognized as a distinct species, though it shared a name with another bearded iris. The clarification of its taxonomy only occurred in 1996.
Description
It is similar in form to Iris × germanica.
It is classed as a medium-sized bearded iris,{{cite web |first=Gianluca |last=Corazza |title=Iris relicta |date=31 May 2013 |url=http://www.signa.org/index.pl?Iris-relicta |publisher=signa.org (Species Iris Group of North America) |access-date=12 November 2015}} and grows up to between {{convert|30|-|40|cm|0|abbr=on}} tall.{{cite web| title=Iris summary |date=14 April 2014 |url=http://www.pacificbulbsociety.org/pbswiki/files/Iris/Iris_Summary.pdf |publisher=pacificbulbsociety.org | access-date=23 November 2014}} It has a branched stem.
Like other irises, it has 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner smaller petals (or tepals), known as the 'standards'.{{cite book |first=Claire |last=Austin |title=Irises; A Garden Encyclopedia |year=2005 |publisher=Timber Press |isbn=978-0881927306 }}{{rp|17}}
The flowers come in shades of purple,{{cite web |first=Alain |last=Franco |title=(SPEC) Iris relicta Colas |date=2 December 2013 |url=http://wiki.irises.org/bin/view/Spec/SpecRelicta |publisher=wiki.irises.org (American Iris Society) |access-date=25 November 2015}} from red-purple, to blue-purple. In the centre of the falls is a 'beard', or line of white hairs.
After the iris has flowered, it produces a seed capsule, that has not been described.
=Biochemistry=
As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings.{{rp|18}}
It has a chromosome count of 2n=40.{{cite journal |last=Colasante |first=Maretta |date=1996 |title=Taxonomic note on some Italian Bearded Irises: Iris relicta Colas. nom. nov. and Iris bicapitata Colas. sp.nov |url=http://147.163.105.223/flora/6-213.pdf |journal=Flora Mediterranea |volume=6 |pages=213 |access-date=14 September 2015}}
It was counted by Colasante & Sauer in 1993 and by Colasante in 1996.
It is the same as Iris setina, Iris bicapitata, Iris lutescens and Iris revoluta.{{cite journal |last=Colasante |first=M. |last2=Vosa |first2=C.G. |date=2000 |title=Iris:Allocyclic segments as Chromosome markers? |url=http://bib03.caspur.it/ojspadis/index.php/Annalidibotanica/article/viewFile/9071/9011 |journal=Annali di Botanica |volume=58 |pages=127–134 |access-date=28 October 2015 }}{{Dead link|date=January 2020 |bot=InternetArchiveBot |fix-attempted=yes }}
Taxonomy
The Latin specific epithet relicta refers to a remnant, primitive, left behind and relict.D. Gledhill {{Google books|NJ6PyhVuecwC|The Names of Plants|page=328}} This name was chosen due to the diminishing size of the population of irises found on the mountains in Italy.
It was first published and described by Nicola Terracciano (1837–1921) as Iris germanica var. suaveolens in 'Atti dell' Accademia delle Scienze Fisiche e' Matematiche (Atti Accad. Sci. Fis.) series 4, (Appendix 2) on page 7 in 1890, as a variety of Iris germanica.{{cite web |title=Iridaceae Iris relicta Colas |url=http://www.ipni.org/ipni/idPlantNameSearch.do?id=994819-1 |publisher=ipni.org (International Plant Names Index) |access-date=12 November 2015}}
It was then published as Iris suaveolens by (N. Terracc.) N. Terracc. ex A. Terracc in 'Nuovo Giorn. Bot. Ital.', series. 2, on page182 in 1894.
But this name was rejected by other authors and iris authorities as it was already used by another iris species, since 1853.
Later it was re-classified as a separate species by Prof. Maretta Colasante in Giornale Botanico Italiano ('Giorn. Bot. Ital.') Vol.123 Supplement 1 on page 112 in 1989, and then called Iris relicta by Colasante in (Fl. Medit.) Vol.6 page 214 in 1996.{{cite web |title=Taxon: Iris relicta Colasante |url=https://npgsweb.ars-grin.gov/gringlobal/taxonomydetail.aspx?432698 |publisher=ars-grin.gov (Germplasm Resources Information Network) |access-date=12 December 2015}} Based on specimens found on 'Monte delle Fate' in Lazio, Italy.
It was verified by United States Department of Agriculture and the Agricultural Research Service on 7 April 2003, and the updated on 3 December 2004.
It is listed in the Encyclopedia of Life,{{cite web |title=Iris relicta |url=http://eol.org/pages/31189228/overview |publisher=eol.org |access-date=25 November 2015}} and in the Catalogue of Life, it is listed as Iris relicta and notes that Iris germanica var. suaveolens is a synonym.{{cite web |title=Iris cuniculiformis |url=http://www.catalogueoflife.org/annual-checklist/2014/search/all/key/Iris+germanica |publisher=eol.org |access-date=25 November 2015}}

=Habitat=
==Synecology==
Part of the Ausoni Mountains are protected by Wilderness Area, (covering 4,230 hectares and was established in 1999), forests (made of oak, cork oak and maple), cover most of the mountain valleys. Under the forest trees are rare and endemic flora, including Crocus imperati subsp imperati, Narcissus poeticus, Asphodeline lutea (Asfodelina), Daphne oleoides (spatula Daphne) and Iris relicta.
Conservation
It is listed as 'very rare', and is protected in the 'Wilderness Area' in Italy.
Cultivation
=Propagation=
Irises can generally be propagated by division,{{cite web |title=How to divide iris rhizomes |url=http://www.gardenersworld.com/how-to/projects/propagating/how-to-divide-iris-rhizomes/169.html |publisher=gardenersworld.com |access-date=12 October 2015}} or by seed growing.
Toxicity
Like many other irises, most parts of the plant are poisonous (rhizome and leaves), and if mistakenly ingested can cause stomach pains and vomiting. Handling the plant may cause skin irritation or an allergic reaction.David G Spoerke and Susan C. Smolinske{{Google books|a7-f66fRfzQC|Toxicity of Houseplants|page=236}}
