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.
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the part of the shoot of seed plants where flowers are formed and which is accordingly modified. 1 A spike is a type of raceme with flowers that do not have a pedicel. 2  A racemose corymb is an unbranched, indeterminate inflorescence that is flat-topped or convex due to their outer pedicels which are progressively longer than inner ones. raceme (rəˈsiːm). 1  an inflorescence in which the flowers are borne along the main stem, with the oldest flowers at the base. 2  It can be simple, as in the foxglove, or compound. noun. 1  an inflorescence in which the flowers are borne along the main stem, with the oldest flowers at the base. 2  It can be simple, as in the foxglove, or compound. 3  See panicle. 1 A flower head or capitulum is a very contracted raceme in which the single sessile flowers share are borne on an enlarged stem. 2  It is characteristic of Dipsacaceae. 3  A catkin or ament is a scaly, generally drooping spike or raceme. 1 A spike is a type of raceme with flowers that do not have a pedicel. 2  A racemose corymb is an unbranched, indeterminate inflorescence that is flat-topped or convex due to their outer pedicels which are progressively longer than inner ones. Spike: Unbranched inflorescence with sessile flowers (no pedicels). Raceme: Unbranched inflorescence with flowers on pedicels. Panicle: A branched or compound raceme (i.e. main rachis with branches bearing flowers on pedicels). Corymb: Flat-topped inflorescence with youngest flowers at the end of main axis or rachis. Cyme: Flat-topped inflorescence with oldest flowers at the end of main axis. Spadix: Inflorescence Of The Arum Family (Araceae) The spadix is the characteristic inflorescence of the remarkable arum family (Araceae). It consists of a thickened, fleshy axis (spike) bearing clusters of sessile, apetalous, unisexual flowers. Inflorescence can also be defined as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. 1 A spike is a type of raceme with flowers that do not have a pedicel. 2  A racemose corymb is an unbranched, indeterminate inflorescence that is flat-topped or convex due to their outer pedicels which are progressively longer than inner ones. 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, axis means a shoot, in this case one bearing the flowers. Examples of racemes occur on mustard (genus Brassica) and radish (genus Raphanus) plants. A spike is an unbranched, indeterminate inflorescence, similar to a raceme, but bearing sessile flowers (sessile flowers are attached directly, without stalks). 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. A spike is an unbranched, indeterminate inflorescence, similar to a raceme, but bearing sessile flowers (sessile flowers are attached directly, without stalks). Examples occur on Malabar nut (Justicia adhatoda) and chaff flowers (genus Achyranthes) Definition of RACEME. : a simple inflorescence (as in the lily of the valley) in which the flowers are borne on short stalks of about equal length at equal distances along an elongated axis and open in succession toward the apex — see inflorescence illustration. ADVERTISEMENT. For example a double raceme is a raceme in which the single flowers are replaced by other simple racemes; the same structure can be repeated to form triple or more complex structures. Compound raceme inflorescences can either end with a final raceme (homoeothetic), or not (heterothetic). 1 A spike is a type of raceme with flowers that do not have a pedicel. 2  A racemose corymb is an unbranched, indeterminate inflorescence that is flat-topped or convex due to their outer pedicels which are progressively longer than inner ones.
