Gynophore

from Wikipedia, the free encyclopedia
Caper flower with gynoeceum sitting on the gynophor
Long gynophores in Crateva magna, a caper plant

In botany, an elongated internode in the flower between the male sexual organs ( Androeceum ) and the female sexual organs ( Gynoeceum ) is called a gynophor (from the Greek gynē , genitive gynaikos = woman, Greek -phoros = -bearing) .

The earliest evidence for the word is the book Élements de physiologie végétable et de botanique by CFB de Mirbel, published in 1815 .

It forms an extension of the floral axis between Gynoeceum and perianth , it is also called punch-holder or ovary carrier designated. The gynophore is pronounced , for example, in some species of the caper family . The sequence of the flower organs, starting from the outside, reads the perianth - Androeceum - Gynoeceum. If instead of the internode between Androeceum and Gynoeceum, the one between the flower envelope and Androeceum as well as the Gynoeceum is stretched, one speaks of an androgynophore . A so-called anthophore is also possible , which is formed between the sepals and the other flower organs in the form of a flower-bearing stalk, and separates both parts, as in the ciliate herbs ( Silene ) in the carnation family .

  • Gynophore

  • Androgynophore

  • Anthophore

A Gynophor is not the same as a pedicled ovary , a prop foot or a Karpophor , the fruit holder, here form other basalt ropes on the ovary a stem or an extension, for the most part carpel derived. However, the term is often used synonymously.

With a cyathium , a reduced and complex inflorescence that appears like a single flower, the middle and raised female flower can also be viewed as standing on a gynophore.
