Irises are perennial herbs, growing from creeping rhizomes,
or, in drier climates, from bulbs. They have long, erect flowering
stems, which may be simple or branched, solid or hollow, and
flattened or have a circular cross-section. The rhizomatous
species usually have 3–10 basal, sword-shaped leaves growing
in dense clumps. The bulbous species have cylindrical, basal
leaves.
Iris Flower Gifts
| The iris flower is of special interest
as an example of the relation between flowering
plants and pollinating insects. The shape of the
flower and the position of the pollen-receiving
and stigmatic surfaces on the outer petals form
a landing-stage for a flying insect, which in probing
the perianth for nectar, will first come in contact
of perianth, then with the stigmatic stamens in
one whorled surface which is borne on an ovary formed
of three carpels. |
