Inflorescence Terms: Indeterminate (Racemose), Determinate (Cymose) and both

Terms	Definitions
inflorescence	a flower cluster; the arrangement of flowers on a floral axis.
peduncle	the stalk to the base of an inflorescence.
rachis	the central stalk (axis) within the inflorescence.
pedicel	the stalk to an individual flower in an inflorescence.
bract	a modified leaf subtending an inflorescence or a flower.
subtend	occurring at the base of another part.
scapose	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.
intercalary	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.
cauliflorus	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.
spike	unbranched indeterminate elongate inflorescence with sessile flowers.
raceme	unbranched indeterminate elongate inflorescence with pedicellate flowers.Examples: foxglove, snapdragon, Acacia baileyana
panicle	a branched indeterminate inflorescence with pedicellate flowers on secondary branches; a compound raceme. Examples: Paulownia, Schinus (Brazilian Pepper), lilac. Indeterminate.
corymb	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
umbel	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.
solitary	a determinate inflorescence composed of a single flower. Example: poppy.
cyme	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.
compound corymb	indeterminate
