Flowers do not appear solitary in a stem. They are generally arranged in a fixed pattern we call inflorescence. Flowers included in the inflorescence are generally called florets. Inflorescences can be:
MAIN SINGLE INFLORESCENCES:
In racemes florets are attached along a floral peduncle with stems similar in length. Young florets appear above and old ones below.
Spikes are inflorescences similar to racemes, but florets are attached directly to the floral peduncle,without stems.
(see image of a spike -Mint - Menta rotundifolia )
In corymbs. all the florets are arranged along a floral peduncle but , differently to racemes, stems have different length in such a way that all the florets appear at the same flat round level.

Panicles are formed by several racemes gathered together.
Compound umbels are formed by several umbels gathered together.
