总状花序（raceme）是一种不分支的花序类型，具带柄花朵，该短柄称之为花梗，沿花序轴排列。总状花序中，早开的花位于底部，新开的花位于顶部。

A raceme (/reɪˈsiːm/ or /rəˈsiːm/) is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers — flowers having short floral stalks called pedicels — along its axis. In botany, an axis means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers are borne towards the base and new flowers are produced as the shoot grows, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. Cimicifuga racemosa. A compound raceme, also called a panicle, has a branching main axis. Examples of racemes occur on mustard (genus Brassica) and radish (genus Raphanus) plants.
