An "umbel" is a type of flower cluster where multiple stems arise from a single point, resembling an umbrella. This structure is common in plants from the Apiaceae family, which includes species like carrots and parsley. Each flower in an umbel is typically small and can vary in color, often forming a flat or rounded shape. Umbels can be classified into two main types: simple and compound. A simple umbel has flowers on individual stems, while a compound umbel features smaller umbels branching off from the main stem. This arrangement helps attract pollinators and can enhance seed production in plants.
