Unbranched, indeterminate type of inflorescence bearing pedicellate flowers along its axis
This article is about the botanical term. For mixtures of chiral compounds in chemistry, see Racemates.
The inflorescence of a Phalaenopsis orchid, is a typical raceme.
A raceme (/reɪˈsiːm,rə-/) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus Brassica), radish (genus Raphanus), and orchid (genus Phalaenopsis) plants.
