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

Origin: [L. racemus a bunch of berries, a cluster of grapes. See Raisin.]
A raceme is a type of inflorescence that is unbranched and indeterminate and bears pedicellate flowers — flowers having short floral stalks called pedicels — along the axis. In botany, axis means a shoot, in this case one bearing the flowers. In a raceme, the oldest flowers are borne towards the base and new flowers are produced as the shoot grows. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. Cimicifuga racemosa. A compound raceme is called a panicle. A spike is a type of raceme in which individual flowers are sessile. The term spikelet can refer to a small spike, although it is primarily used to refer to the ultimate flower cluster unit in the grasses, in which case the stalk supporting the cluster becomes the pedicel. A true spikelet comprises one or more florets enclosed by two glumes, and is not a raceme. A spadix is a form of spike in which the florets are densely crowded along the axis. They are enclosed or accompanied by a highly specialized bract called a spathe and are a characteristic of the Araceae family.
