Bulb Irises vs. Rhizome Irises

The 27 Most Common Iris Flowers
Even though there are only two categories of irises, there are way more than just two types of irises. Instead, there are dozens of iris flowers, each one belonging to one of the two categories described above.

Taxonomy
Iris is the largest genus of the family Iridaceae with up to 300 species – many of them natural hybrids. Modern classifications, starting with Dykes (1913), have subdivided them. Dykes referred to the major subgroupings as sections. Subsequent authors such as Lawrence (1953) and Rodionenko (1987) have generally called them subgenera, while essentially retaining Dykes' groupings, using six subgenera further divided into twelve sections. Of these, section Limneris (s…
Evolution
The concept of introgressive hybridization (or "introgression") was first invented to describe the pattern of interspecific hybridization followed by backcrossing to the parentals that is common in this genus.
• Iris (Bearded rhizomatous irises)
• Limniris (Beardless rhizomatous irises)
Distribution and habitat
Nearly all species are found in temperate Northern Hemisphere zones, from Europe to Asia and across North America. Although diverse in ecology, Iris is predominantly found in dry, semi-desert, or colder rocky mountainous areas. Other habitats include grassy slopes, meadowlands, bogs and riverbanks.
Cultivation

Water purification
In water purification, yellow iris (I. pseudacorus) is often used. The roots are usually planted in a substrate (e.g. lava-stone) in a reedbed-setup. The roots then improve water quality by consuming nutrient pollutants, such as from agricultural runoff. This highly aggressive grower is now considered a noxious weed and prohibited in some states of the US where it is found clogging natur…
Overview
In humans and most mammals and birds, the iris (plural: irides or irises) is a thin, annular structure in the eye, responsible for controlling the diameter and size of the pupil, thus the amount of light reaching the retina. Eye color is defined by that of the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm.
Structure
The iris consists of two layers: the front pigmented fibrovascular layer known as a stroma and, beneath the stroma, pigmented epithelial cells.
The stroma is connected to a sphincter muscle (sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles (dilator pupillae), which pull the iris radially to enlarge the pupil, pulling it in folds.
Eye color
The iris is usually strongly pigmented, with the color typically ranging between brown, hazel, green, gray, and blue. Occasionally, the color of the iris is due to a lack of pigmentation, as in the pinkish-white of oculocutaneous albinism, or to obscuration of its pigment by blood vessels, as in the red of an abnormally vascularised iris. Despite the wide range of colors, the only pigment that contri…
Clinical significance
• Angle closure glaucoma
• Anisocoria
• Horner's syndrome
• Iridocyclitis
• Iritis
Alternative medicine
Iridology (also known as iridodiagnosis) is an alternative medicine technique whose proponents believe that patterns, colors, and other characteristics of the iris can be examined to determine information about a patient's systemic health. Practitioners match their observations to "iris charts", which divide the iris into zones corresponding to specific parts of the human body. Iridologists see the eyes as "windows" into the body's state of health.
Etymology
The word "iris" is derived from the Greek goddess of the rainbow, because of the many colours of the iris.
