Iris subg. Iris:

Subgenus Iris is one subgenus of Iris, The genus was originally clasified by Carl Linnaeus, but then further organised by Brian Mathew between 1981 and 1987.[1]

It has been divided into six sections; Bearded irises (or pogon irises), Psammiris, Oncocylclus, Regelia, Hexapogon and Pseudoregelia.



Section Bearded irises (or pogon irises)[edit]

This is the largest section of the subgenus. Most irises come from Southern or eastern Europe.[1] Note 'pogon' refers to the Greek word for beard.[2] It has several species of iris including;


Bearded Iris hybrid 'Stepping out'

It also includes thousands of hybrids which have been divided into various height categories.[3]

  • MDB - Miniature Dward bearded
  • SDB - Standard Dwarf bearded
  • IB - Intermediate bearded
  • BB - Border bearded
  • MTB - Miniature Tall bearded
  • TB - Tall bearded

Psammiris[edit]

This section of irises was first described by Spach. Irises from Russia and Northwest china. Mostly rhizomatous, and flowering in late spring.[1] Note psammos derives from the Greek word for sand.[2]


Iris humilis subsp.arenaria

Oncocylus[edit]


Iris atropurpurea from Israel

All irises are rhizomatous perennials. They also generally need rich soils that drain easy and are in full sun. Most also prefer a dry period after flowering.[5] Irises mostly from Turkey, Caucasus and Iran. The flowers usually only have one flower. Some of these species have been bred with bearded irises to create unique colours and markings.[1] Oncocyclus is a Greek word, with onco meaning mass, or bulk, and cyclus meaning circle.[6]

Regelia[edit]


Iris hoogiana

Mostly from the mountainous regions of Iran, Afghanistan and the Altai Mountains.[7] Most irises have a stem that has 2 flowers.[1] It was named in 1904 by Robert Lynch in his book 'The Book of The Iris' after Dr Regel.[8]

Hybrids of Regelia irises and Oncocyclus irises are known as 'Regelicyclous'.[9]

Hexapogon[edit]

Mostly from the desert area of Central Asia, Iran and Afghanistan. Most irises have beards on the falls and standards.[1] Note 'hexa' refers to the number 6 and 'pogon' refers to the Greek word for beard.[2]

Pseudoregelia[edit]

Mostly from the mountainous regions of Eastern Asia. Most irises have flowers that have blothes or colour spots on.[1]

Tigridia pavonia:

Tigridia pavonia is the best-known species from the genus Tigridia, in the Iridaceae family. Common names include jockey's cap lily,[3] Mexican shellflower[4] peacock flower,[4] and tiger flower.[4] The species is widespread across much of Mexico as well as Guatemala, El Salvador, and Honduras. The species is also considered naturalized in Ecuador and Peru.[4][5]

It is very popular as an ornamental plant among lovers of interesting flowers. The blooms come in a variety of colours. They open early in the morning and are already closed around 5 P.M. when dusk begins to fall. Every day a different bloom is opened. The plants that are grown from seeds bloom in the first year after they are sowed.
