hey...i cant understand the floral diagrams..i feel it very complicated
Dear Student,
You just need to understand the basic floral diagrm for each famly and rest will be easy to draw. Below I have provided a table which gives the detailed information about the families and the floral diagram. Just try to understand them. I am sure after this you will be able to make floral diagram for different flowers belonging to the different families. Its just that it needs lots of practice.
