Panicle
A panicle is a much-branched inflorescence.[1] Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower). The branches of a panicle are often racemes. A panicle may have determinate or indeterminate growth.
This type of inflorescence is largely characteristic of grasses such as oat and crabgrass,[a] as well as other plants such as pistachio and mamoncillo. Botanists use the term paniculate in two ways: "having a true panicle inflorescence"[b] as well as "having an inflorescence with the form but not necessarily the structure of a panicle".
Corymb[edit]
A corymb may have a paniculate branching structure, with the lower flowers having longer pedicels than the upper, thus giving a flattish top superficially resembling an umbel. Many species in the subfamily Amygdaloideae, such as hawthorns and rowans, produce their flowers in corymbs.
