Raceme vs. Corymb — What's the Difference?

A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called pedicels) along its axis. In botany, an axis means a shoot, in this case one bearing the flowers.

Corymb is a botanical term for an inflorescence with the flowers growing in such a fashion that the outermost are borne on longer pedicels than the inner, bringing all flowers up to a common level. A corymb has a flattish top with a superficial resemblance towards an umbel, and may have a branching structure similar to a panicle.

An inflorescence having stalked flowers arranged singly along an elongated unbranched axis, with the flowers at the bottom opening first.

A usually flat-topped flower cluster in which the individual flower stalks grow upward from various points of the main stem to approximately the same height.

(botany) An indeterminate inflorescence in which the flowers are arranged along a single central axis.

(botany) A cluster of flowers with a flat or convex top.

A flower cluster with an elongated axis and many one-flowered lateral pedicels, as in the currant and chokecherry.

A flat-topped or convex cluster of flowers, each on its own footstalk, and arising from different points of a common axis, the outermost blossoms expanding first, as in the hawthorn.

Usually elongate cluster of flowers along the main stem in which the flowers at the base open first

Flat-topped or convex inflorescence in which the individual flower stalks grow upward from various points on the main stem to approximately the same height; outer flowers open first
