Cymose Inflorescence and Its Types
Cymose Inflorescence:
- This type of inflorescence is also known as determinate or definite inflorescence.
- Each peduncle or axis, whether main or axillary terminates into a flower.
- Younger flowers arise from the base of the older ones.
- Hence, the arrangement of flowers is in basipetal succession, that is, the older ones appear at the top and the younger ones at the base.
Uniparous / Monochasial Cyme:
- Main axis terminates into a flower.
- The lateral branch arise at the base of the terminal flower and acts as main axis.
- It also terminates into the flower.
- Monochasial cyme is of two types:
- Helicoid Monochasial Cyme: successive branching occurs at the same side such that the inflorescence acquires helical shape, e.g., Begonia, Drocera, etc.
- Scorpioid Monochasial Cyme: successive branching occurs on both sides in zig-zag or alternate manner, e.g., Ranunculus.
