Corymbs

Corymb is a botanical term for an inflorescence with the flowers growing in such a fashion that the outermost are born on longer pedicels than the inner, bringing all flowers up to a common level. A cyme has a flattish top superficially resembling an umbel, and may have a branching structure similar to a panicle. Flowers in a corymb structure can either be parallel, or alternate, and form in either a convex, or flat form.

Many species in the Maloideae, such as hawthorns and rowans, produce their flowers in corymbs. The Norway maple and yerba maté are also examples of corymbs.
