Raceme

The inflorescence of a Phalaenopsis orchid is a typical raceme.

A raceme (/rˈsm, 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.
