Parts of an Iris Flower:
S- standards the upturned three petals, (technically called sepals) that surround the three style arms
F – falls the downturned three petals, (correctly called petals) that possess beards. These may also be horizontally flared or flat instead of downturned)
B – beards Elongate groups of fuzzy hairs in the middle at the upper base of all three falls
SASpace Age Space Age iris have something extra, beard appendages called horns, spoons or flounces
Spoons Appendages extending from the tip of the beards that widen into spoon shaped petaloids.
Horns A protrusion or extension of the beards, often ending in a point or may be hair covered.
Flounces Wide, folded, often canoe or fan shaped appendages extending from the tips of the beards.
Hafts Areas on each side of the narrow of the falls, on each side of the beards
Shoulders The areas on the arching upper middle part of the falls on each side just beyond the haft areas.
Pistil The style arms with stigmatic lips and the ovary. The female flower parts
Claw The narrow base of the standard and fall, the expanded leaf-like part is called the blade.
Ovary The enlarged green, three-chambered structure enclosing the ovules where fertilization occurs.
Spathes The pair of modified green leaves that enclose the flower bud, usually turning tan after it blooms.
Stamen The anther plus its attachment filament. The anthers contain the granular pollen. The male flower parts.
