Mixed Inflorescence

Inflorescences may also have classified based on branching, number and arrangement of flowers, and some specialized structures.

I.   Indeterminate (racemose)

II.   Determinate (cymose)

III.   Mixed inflorescence: Inflorescence of some plants show a combination of indeterminate and determinate pattern

IV.   Special inflorescence: Inflorescence which do not confined to these patterns

Mixed Inflorescence

Inflorescences in which both racemose and cymose patterns of development occur in a mixed manner. It is of the following two types.

1. Thyrsus: It is a ‘Raceme of cymes’. Indefinite central axis bears lateral pedicellate cymes, (simple or compound dichasia). Example: Ocimum, Anisomeles.

2. Verticil or Verticillaster: Main axis bears two opposite lateral sessile cymes at the axil of the node,each of it produces monochasial scorpioid lateral branches so that flowers are crowded around the node. Example: Leonotis, Leucas.
