A (racemose or indefinite) inflorescence with branches arising from more or less the same point on a common peduncle. (In a simple umbel, each ray terminates in a flower; in a compound umbel, each ray itself bears an umbel, the latter being called a partial umbel).
An inflorescence in which the pedicels originate from one point on top of the peduncle and are usually of equal length.
Umbrella-like arrangement of flowers with all flower stems arising from the same point.
Umbrella-shaped inflorescence (flower cluster) in which pedicels (stalks of flowers or flower clusters) radiate from a common point, like the ribs of an umbrella.
A type of flower cluster. The individual flowers occur on stems of nearly equal length; the stems unite at one point, at the top of the flower stalk.
A flat-topped or slightly convex flower cluster in which a number of flower stalks of nearly equal length arise from the same center point.
A flowering head where the pedicels (individual flower stems) all spring from one point, usually the end of the peduncle. Compound umbels, found in some Umbelliferae, have umbels branching from peduncle umbels that them-selves are branching from the main stem.
A raceme in which the axis has not elongated, so that the flowers stalks arise at the same point. Thus the flowers are in a head, with the oldest at the outside.
A flower grouping with individual flower stalks or groups radiating from a central axis, often flat-topped and umbrella-like.
An indeterminate inflorescence in which a number of nearly equal peduncles radiate from a small area at the top of a very short axis, giving an umbrellalike appearance.
Said of an arrangement of peduncles when like the ribs of an umbrella, bearing flowers in a flat or convex canopy.
Inflorescence with numerous stalked flowers radiating from a single point, as in dill and fennel.
An umbrella-shaped flower cluster with all flower stalks evolving from same point.
An inflorescence with all branches arising (more or less) from the same point on a common peduncle; compound umbels are an umbel on which each branch bears another umbel.
A ± flat-topped inflorescence, with several branches all rising from one point at the top of the main stem; it may be simple (composed of one whorl of unbranched branches only), or compound (when each branch in turn bears a similar ‘secondary’ or ‘partial’ umbel).
A type of inflorescence where several flower stalks arise from one point, as in onions, agapanthus and parsley.
An umbrella-shaped inflorescence in which all the pedicels are attached to a common point.
A type of inflorescence in which several to many flower stalks arise from one point, as in onions, agapanthus or parsley.
A cluster of flowers formed by stalks of nearly equal length springing from a common centre. The individual flowers form a flat or convex or concave surface. This type of flower cluster is characteristic of the Umbelliferae family.
