Translationsumbel
umbel an inflorescence, characteristic of umbelliferous plants, in which the flowers arise from the same point in the main stem and have stalks of the same length, to give a cluster with the youngest flowers at the centre Umbel a cluster of plants whose flower scapes are all of the same length and branch out as if from the apex of a shortened main rachis. The flowers, therefore, are located much at the same level (in cherry blossoms, primroses, and masterworts). The peripheral flowers in the umbel open first, and then the inner ones blossom. Plants frequently have compound umbels, formed by small umbels with short scapes that are located in place of flowers on long rachises that branch out from the apex of the main rachis. Such small umbels are called umbellets, and the rachises on which they sit are called rays. Compound umbels are characteristic of almost all the plants of the family Umbelliferae (carrots, dill, angelica). umbel[′əm·bəl] (botany) An indeterminate inflorescence with the pedicels all arising at the top of the peduncle and radiating like umbrella ribs; there are two types, simple and compound. umbel
umbel an umbrella-shaped inflorescence that forms a RACEME in which the central axis has not elongated. Examples include the flowers of cow parsley, parsley, lovage.umbel
