Umbel
An umbel is an inflorescence which consists of a number of short flower stalks (called pedicels) which spread from a common point, somewhat like umbrella ribs. The word was coined in botany in the 1590s, from Latin umbella "parasol, sunshade." The arrangement can vary from being flat topped to almost spherical. Umbels can be simple or compound. The secondary umbels of compound umbels are known as umbellules or umbellets. A small umbel is called an umbellule. The arrangement of the inflorescence in umbels is referred to as umbellate, or occasionally subumbellate (almost umbellate).
