In botany, an inflorescence is a group or cluster of flowers arranged on a plant's stem that is composed of a main branch or a system of branches. [1] An inflorescence is categorized on the basis of the arrangement of flowers on a main axis and by the timing of its flowering (determinate and indeterminate). [2]
They usually present floral nectarys and the secretion of nectar comes from the perigonium or gynoecium, usually in the septa of the ovary. [32] [33] The flowers are arranged in cymose inflorescences at the apex of a scape, sometimes compressed and umbel-like, and are thus called "pseudoumbels". They are rarely reduced to solitary flowers.
adj. cymose. A type of inflorescence in which the main axis and all lateral branches end in a flower (each lateral may be repeatedly branched). cymose Having a cyme or cymes. cypsela A type of dry, one-seeded, indehiscent fruit formed from an inferior ovary
Sympodial growth occurs when the apical meristem is terminated and growth is continued by one or more lateral meristems, which repeat the process. The apical meristem may be consumed to make an inflorescence or other determinate structure, or it may be aborted.
The meristem can be defined as the tissue or group of plant tissues that contain undifferentiated stem cells, which are capable of producing any type of cell tissue.Their maintenance and development, both in the vegetative meristem or the meristem of the inflorescence is controlled by genetic cell fate determination mechanisms.

Pedicel – the stem or stalk that holds a single flower in an inflorescence. Peduncle – the part of a stem that bears the entire inflorescence, normally having no leaves, or the leaves having been reduced to bracts. When the flower is solitary, it is the stem or stalk holding the flower. Peduncular – referring to or having a peduncle.
