Although iris bloom have all the same basic element as other bloom , they have some special feature as well . flag are passing well - equip to both draw in pollenate insects and help the insects to change the pollen into their ovaries . Flower parts in the iris are not simply designed to make the blossoms beautiful , but are made with insects in mind .
Perianth
The perigonium contains both the petals ( corolla ) and the sepals ( calyx ) of the iris blossom . The sepal are the outer petal - like structures that protect the iris flower before it blooms and unfold . Instead of straight sepal like other efflorescence , irises have " fall . "
Falls
Part of the perianth , the petal - similar falls attract cross-pollinate insects to the centre of the flush with a bright - colored middle production line in each of the falls . The descent also flatten out and bend down to act as a landing place website for the dirt ball . In most irises , the gloam are lighter in colour than the rest of the petal , usually a shocking white or yellow .
Standards
Each iris efflorescence has three standards , or erect inner petal . Like the fall , the criterion also attract pollinating insects to the efflorescence ’s nectar . Unlike the outer petals with the spill , however , the touchstone are unremarkably solid in color , without the central funnies of lighter coloring .
Style Arms
The style arms of the iris flower are part of the pistil , or female reproductive organ . iris ' fashion arms are located in the marrow of the bloom and resemble petal , unlike other flower that have a distinguishable flair connecting the ovary to the stigma .
Stigmatic Lip
The stigmatic lip represent as the stigma in the iris flower . The anastigmatic lip helps to rub the pollen from the worm ’s consistence into the pollen underground that carries the male reproductive pollen grains down to the ovary . The anastigmatic lip is located at the top of the style branch .
Stamen
Beneath the arched style limb is the stamen , which contain the manly reproductive pollen grain . In the iris flower , the stamen grows in the center of the bloom , powerful beside the style arm . Because the stamen spring up so close to the style arm , pollen metric grain easily transfer to the female generative organs .
Beard
Many specie of iris efflorescence have beards . The beard is a fuzzy structure that grows on the top surface of the falls . The beard serves as a perching setup that offer pollinating insects a clutches to hold onto when they ’re enter the iris flush to look for ambrosia .
