Definition
Noun: - A type of plant placentation: In botany, this term refers to the arrangement of ovules (the structures that develop into seeds) along the wall of a simple ovary, specifically along its ventral suture (the seam or line of fusion).
Usage
This is a highly specific botanical term used to describe the internal structure of a flower's ovary. - Ventral placentation is a characteristic feature in the flowers of the pea family (Fabaceae). - The botanist identified the plant by examining its ventral placentation under a microscope.
Advanced Usage
- In botanical classification: This term is used in plant taxonomy and morphology to differentiate between types of placentation (e.g., axile, parietal, free-central, basal).
- The key to distinguishing this genus lies in its unique ventral placentation.
Variants and Related Words
- Placentation (n): The general arrangement of ovules within the ovary of a flowering plant.
- Ovule (n): The structure in seed plants that develops into a seed after fertilization.
- Ovary (n): The part of a flower's pistil that contains the ovules.
- Suture (n): In botany, a seam or line of fusion, especially on a fruit or ovary.
Synonyms
- Marginal placentation: This is often used as a synonym, as the ventral suture is typically the margin of the carpel (the ovule-bearing unit).

Noun
- with ovules borne on the wall along the ventral suture of a simple ovary
