The column, or technically the gynostemium, is a reproductive structure that can be found in several plant families: Aristolochiaceae, Orchidaceae, and Stylidiaceae.
It is derived from the fusion of both male and female parts (stamens and pistil) into a single organ.[1] The top part of the column is formed by the anther, which is covered by an anther cap. This means that the style and stigma of the pistil, with the filaments and one or more anthers, are all united.
