Inflorescence Terms: Indeterminate (Racemose), Determinate (Cymose) and both
a flower cluster; the arrangement of flowers on a floral axis.
the stalk to the base of an inflorescence.
the central stalk (axis) within the inflorescence.
the stalk to an individual flower in an inflorescence.
a modified leaf subtending an inflorescence or a flower.
|subtend||occurring at the base of another part.|
developing on a leafless or nearly leafless peduncle or scape arising directly from the base of the plant. Synonym: basal. Example: dandelion.
|axillary||developing from a leaf axil.|
|terminal||developing at the terminal end of a shoot.|
a terminal inflorescence where vegetative growth continues after flowering occurs, so the inflorescence seems to have arisen in the middle of a stem. Example: bottlebrush.
developing directly from a woody trunk. Example: redbud.
|Indeterminate|| (Racemose) OLDEST AT BOTTOM or OUTSIDE; |
an inflorescence in which lateral flowers develop first, while the floral axis continues to grow. Flowers mature from base to apex.
unbranched indeterminate elongate inflorescence with sessile flowers.
unbranched indeterminate elongate inflorescence with pedicellate flowers.Examples: foxglove, snapdragon, Acacia baileyana
a branched indeterminate inflorescence with pedicellate flowers on secondary branches; a compound raceme.
Examples: Paulownia, Schinus (Brazilian Pepper), lilac. Indeterminate.
a convex or flat-topped raceme, where the lower pedicels are longer than the upper, bringing all the flowers to approximately the same level. Indeterminate
a convex or flat-topped inflorescence without a rachis, where all the pedicels originate from the same point on the peduncle, much like an umbrella. Example: onion. Can be determinate or indeterminate.
|compound umbel|| |
an umbel where each primary branch (ray) terminates in another, smaller umbel (an umbellet) carrying the flowers. Example: many members of the carrot family, such as Queen Anne's lace. Can be determinate or indeterminate.
|Determinate||(Cymose) OLDEST AT TOP or CENTER; an inflorescence in which the terminal or central flower develops first, which arrests further elongation of the floral axis. Flowers mature from apex to base.|
a determinate inflorescence composed of a single flower. Example: poppy.
broad, convex or flat-topped, or long determinate cluster, with central flowers opening first. Specialized terminology can be applied depending on the type of cyme. A cyme developing along two axes may be a dichasium, compound dichasium, or compound cyme. A cyme developing along only one axis may be a elicoid cyme (bostryx), scorpioid cyme (cincinnus), rhipidium or drepanium. Examples: rose, liatris.
