Floral Diagram
Understanding and interpreting the graphical representation of a flower's cross-section, showing the arrangement and number of its parts.
What is Floral Diagram?
A diagrammatic representation of the transverse section of a flower, showing the arrangement and number of floral organs in relation to the mother axis.
Key points
- To interpret the information presented in a floral diagram.
- To draw a floral diagram from a given flower description or specimen.
- To relate floral diagrams to floral formulas.
- To identify floral characteristics from a diagram.
Common exam trap
Confusing the posterior side (mother axis) with the anterior side.
