umbel
Quick Summary
In botany, an umbel is a type of flower cluster where individual flower stalks (pedicels) grow from about the same point, creating a flat or rounded shape. This arrangement is typical of plants in the carrot family. The term "umbel" comes from the Latin word for umbrella, reflecting the flower cluster's appearance.1
The order Umbellales refers to a large group of herbaceous dicotyledonous plants characterized by having umbels or corymbs of small flowers. Many of these plants are economically significant, including the carrot and parsnip. The combining form "umbell-" is used in botanical terms to indicate a connection to umbels or an umbel-like structure.23
