The basic definition for this term is: group of two or more flowers on the same stalk or peduncle. An inflorescence can vary greatly in format, from the long spike, like the Gladioli, to the larger and rounder, like hydrangea. (Also see raceme, panicle, spike and umbel.)
Group of fruits developed by the development of the ovaries in the flowers from an inflorescence, like the pineapple or jack.
Space between nodes on a stem or branch
Received its name in homage of the Greek Goddess of the rainbow.
Spike: Type of long inflorescence without branching, formed by flowers fixed on a single axis. Similar to the raceme; the difference between them is the absence of pedicels in the spike’s flowers. E.g., gladioli.
