Cymose: Central axis stops growing and ends in a flower, Further growth is by means of axillary buds. Old flowers present at apex and young flowers at base.
Types of cymose:
Simple cyme (Solitary): Determine inflorescence consists of a single flower. It may be terminal or axillary. Eg: Hibiscus.
2. Monochasial Cyme (Uniparous): The main axis ends with a flower. From two lateral bracts, Only one branch grows further. It may be Helicoid or Scorpioid.
(a) Helicoid: Axis develop on only one side and looks like a coil, atleast during the stage of early development. Eg: Hamelia, Potato.
(b) Scorpioid: Monochasial cyme in which axes develop on alternate sides. Eg: Heliotropium.
3. Simple dichasium (Biparous):
(i) A central axis ends in a terminal flower, further growth is produced by two lateral buds.
(ii) Each cyme consists of three flowers of which central one is old one. This is true cyme. Eg: Jasminum.
4. Compound dichasium: It has many flowers. A terminal old flower has lateral simple dichasial cyme on both sides. Each compound dichasium consists of seven flowers. Eg: Clerodendron
5. Polychasial Cyme (Multiparous): The central axis ends with a flower. The lateral axes branches repeatedly. Eg: Nerium.
