Pseudostigma

Pseudostigma is a term used in botany to describe a structure that resembles a stigma but is not the true receptive surface of a carpel. Stigmas are typically the uppermost part of a pistil or carpel in a flower, responsible for receiving pollen. Pseudostigmas, however, can arise from various parts of the flower or even from other plant organs and may mimic the appearance or function of a stigma, such as attracting pollinators or aiding in pollen capture. They are not homologous to the true stigma and are not involved in fertilization. Their presence can sometimes lead to confusion in plant identification or evolutionary studies. Examples of structures that might be considered pseudostigmas can include modified petals, sepals, or bracts that have developed a sticky or hairy surface, or a shape that resembles a stigma. The precise definition and application of the term can vary among botanists and depending on the specific plant group being studied. Understanding the distinction between a true stigma and a pseudostigma is crucial for accurate botanical descriptions and interpretations of floral morphology and reproductive biology.
