 |
| Cyme | A determinate inflorescence in which growth of the central axis is terminated by a flower that opens first and each branch or pair of branches subtending this flower then is terminated by a single flower. This pattern, when repeated several times, often results in a somewhat flat-topped inflorescence. |  |
| Cymose | Like a cyme. | |
| Cymule | A small cyme. | |
| Determinate inflorescence | A type of inflorescence in which the terminal or central flower opens first; for example in cymes. | |
| Dichasial cyme | A determinate inflorescence in which growth of the central axis is terminated by a flower that opens first and each pair of branches subtending this flower then is terminated by a single flower. | |

| Flagelliflorous | A plant with a whiplike inflorescence that usually hangs below the crown. |  |
| Glomerule | A tightly congested cymose inflorescence or inflorescence derived from it, usually with sessile flowers; e.g., in the Asteraceae. | |
| Head | Same as capitulum in the Asteraceae. | |
| Helicoid cyme | A determinate inflorescence that has the lateral flowers developing on alternate sides of the axis and often appears coiled. | |

| Inflorescence | The structure in which the flower or flowers are displayed on a plant. |  |
| Involucre (diminutive = involucel) | A series of fused, overlapping, or free bracts that subtend inflorescences (e.g., in some Apiaceae, many Asteraceae, and Euphorbia of the Euphorbiaceae) or flowers (e.g., the female flowers of species of hickory (Carya spp.). |  |
| Ligulate capitulum (head) | Inflorescence of Asteraceae with only ligulate flowers. | |
| Pale | A bract found in the head of Asteraceae. | |
| Paleate (paleaceous) | Possessing pales. | |
| Panicle | A compound raceme in which the primary branches are racemose, which, in turn, give rise to secondary and sometimes higher order racemose branches. |  |
| Peduncle | The stalk of an inflorescence. |  |
| Peduncular bract | A bract on the peduncle in Arecaceae located on the main axis of the inflorescence between the prophyll and the first bract of the rachis; any bract associated with the peduncle; e.g., in the Orchidaceae. |  |
| Pedunculate | Possessing a peduncle. | |
| Pherophyll | Leaflike bract found in frondose inflorescences. | |
| Phyllary (plural = phyllaries) | One of a series of overlapping bracts that subtends the capitulum (head) of Asteraceae. |  |
