Compound corymb -It is a modified raceme with relatively a short main axis, in which the lower flowers have much elongated pedicels so that the flowers come to the same level. Typical example Cauliflower
- Compound umbel - In a compound umbel, all the umbel inflorescences arise from a common point and appear to be at about the same level (example-wild carrot, coriander)
This organization is the same for compound spikes, catkins, corymb, and heads.
- Compound head- A dense concave, convex, spherical or flat - topped inflorescence of numerous sessile flower clustered on a common disc or receptacle. A capitulum is usually subtended by an involucre of bracts. Eg. Compositae (Asteraceae) family.
- Compound raceme- A compound raceme, also called a panicle, had a branching main axis. Examples of racemes occur on mustard (genus Brassica) and radish (genus Raphanus) plants.
