Stoloniferous rhizomes, Iris Paradoxa are sometimes small 1cm, but the plant has very developed secondary roots. These stretch in two wicks sometimes three, lie deep in the ground.
The leaves are lanceolate, greenish-gray, crescent-shaped, they are no more than 4 cm long.
The stem is also small door 1, see 2 inflorescences. One of his paradoxes, and they are numerous, and that the leaves are the roots do not occupy more than 10cm square, while the flower is much more developed. The flower blossoms between April and May. Brown to black, it is disproportionate compared to its very small leaves, extremely reduced. It's a beautiful Oncocyclus with surprising shapes. The erected petals form the bulk of the flower, lined with purple. The sepals are reduced to tabs that bear a pretty beard. Iris Paradoxa at the least developed falls of the genus iris.<ref name="irisbotanique">{{cite web |title=chapitre I (partie 5) Les Oncocyclus II |url=http://irisbotanique.over-blog.com/article-chapitre-i-partie-5-les-oncocyclus-ii-124148159.html |website=dictionaire des iridacée |publisher=irisbotanique.over-blog.com |accessdate=30 November 2019 |language=fr}}</ref>

Iris paradoxa
Botanical Description
About 15-25 cm in height. Leaves falcate, 2-4mm wide. Flowers to 10cm in diameter, with short, narrow, horizontal to somewhat arching, extensively bearded falls and very large erect, rounded standards. The colour varies greatly; the falls may be blackish-violet to golden yellow and the standards white with darker veins to uniform deepest purple, pale blue or pale yellow, early summer.<ref name="Alpine">{{cite web |title=Iris paradoxa |url=http://encyclopaedia.alpinegardensociety.net/plants/Iris/paradoxa?sessionid=DAFAC31909783BD6248D9410C9F4DE02 |website=Alpine Garden Society |accessdate=22 February 2020 |language=en}}</ref>

I. paradoxa is a rhizomatous herbaceous perennial, 10-25cm high, with narrow leaves 2-4mm wide, and flowers in spring or early summer. The erect standards may be white, veined with deep blue-violet, to uniform deepest purple, pale blue or pale yellow; the somewhat horizontal falls may be blackish-violet, through pale purple densely overlaid with black-purple veins, to golden yellow, and the beards are velvety black-purple; it is dormant in late summer<ref name="RHS">{{cite web |title=Iris paradoxa |url=https://www.rhs.org.uk/Plants/9331/i-Iris-paradoxa-i/Details |website=rhs.org.uk |accessdate=22 February 2020}}</ref>

The paradox of this species is to have very small external tepals ("sepals"). The beard is well developed, almost black. The internal tepals ("petals") are lined with purple on a white (choschab form) or purple to mauve (paradoxa form) background.

Of delicate culture, like the other species of the Oncocyclus group.<ref name="bulbeuses">{{cite web |title=Iris paradoxa |url=http://www.iris-bulbeuses.org/iridaceae/iris-paradoxa.htm |publisher=iris-bulbeuses.org |accessdate=26 August 2020 |language=French}}</ref>

Description

I. nectarifera has


Stoloniferous rhizomes, Iris Paradoxa are sometimes small 1cm, but the plant has very developed secondary roots. These stretch in two wicks sometimes three, lie deep in the ground. The leaves are lanceolate, greenish-gray, crescent-shaped, they are no more than 4 cm long. The stem is also small door 1, see 2 inflorescences. One of his paradoxes, and they are numerous, and that the leaves are the roots do not occupy more than 10cm square, while the flower is much more developed. The flower blossoms between April and May. Brown to black, it is disproportionate compared to its very small leaves, extremely reduced. It's a beautiful Oncocyclus with surprising shapes. The erected petals form the bulk of the flower, lined with purple. The sepals are reduced to tabs that bear a pretty beard. Iris Paradoxa at the least developed falls of the genus iris.[2]

Iris paradoxa Botanical Description About 15-25 cm in height. Leaves falcate, 2-4mm wide. Flowers to 10cm in diameter, with short, narrow, horizontal to somewhat arching, extensively bearded falls and very large erect, rounded standards. The colour varies greatly; the falls may be blackish-violet to golden yellow and the standards white with darker veins to uniform deepest purple, pale blue or pale yellow, early summer.[3]

I. paradoxa is a rhizomatous herbaceous perennial, 10-25cm high, with narrow leaves 2-4mm wide, and flowers in spring or early summer. The erect standards may be white, veined with deep blue-violet, to uniform deepest purple, pale blue or pale yellow; the somewhat horizontal falls may be blackish-violet, through pale purple densely overlaid with black-purple veins, to golden yellow, and the beards are velvety black-purple; it is dormant in late summer[4]

4-10" (1025 cm). Standards purple or violet; falls darker; blackish beard. 2n=20. [5]

General Description:Grows 4"-10" tall. Standards are purple or violet. Falls are darker, with a blackish beard. [6] Distinguishing Features:This is the only iris with falls that are extremely smaller than the standards.[6]

The paradox of this species is to have very small external tepals ("sepals"). The beard is well developed, almost black. The internal tepals ("petals") are lined with purple on a white (choschab form) or purple to mauve (paradoxa form) background.

Of delicate culture, like the other species of the Oncocyclus group.[7]

Height: under 6 in. (15 cm) - 6-12 in. (15-30 cm) Bloom Color: Lavender,Medium Purple,Dark Purple/Black Bloom Time: Early (E) + Early midseason (EM) Foliage Color: Blue-Green[8]

Height 4-10" (10-25 cm). Described in Flora USSR: "Falls almost black violet, standards bright violet or dark violet blackish purple hairs."[9]

Paradoxa deserves its name for, whereas in most irises the standards are smaller than the falls, in this case the falls are merely narrow straps covered as it were with black velvet, while the standards are large and circular, veined with deep blue on a bluish-white ground.[10]

Like other irises, the flowers have 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals, known as the 'standards'.[11] 7–8.5 cm (3–3 in) long

Biochemistry

As most irises are diploid, meaning having two sets of chromosomes. This can be used to identify hybrids and classification of groupings.[11] 2n=20 [6]Chromosomes: 2n = 20[2]

Taxonomy

Iris paradoxa f. choschab from Gothenburg Botanical Garden, Sweden

Unusual iris[4] Species: paradoxa (par-uh-DOKS-uh) (Info)[8] Iris paradoxa was rightly named " the unexpected," for it is entirely unlike any other species.[10]


It was first published and described by Steven in
