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:
  1. Helicoid Monochasial Cyme: successive branching occurs at the same side such that the inflorescence acquires helical shape, e.g., Begonia, Drocera, etc.
  2. Scorpioid Monochasial Cyme: successive branching occurs on both sides in zig-zag or alternate manner, e.g., Ranunculus.
