| 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. |  |
| Pleiochasium | Referring to a cyme in which each of the main axes produces more than two branches. | |
| Pleiothyrse | A complex thyrse; e.g. those of some species of Apocynaceae subfamily Asclepiadoideae. | |
| Pseudoraceme | A raceme of 1-flowered cincinni. | |
| Raceme | An indeterminate inflorescence with a single axis, the flowers borne on pedicels of more or less equal length, and the uppermost flower the youngest. Compare with spike. |  |
| Racemose | Racemelike. | |
| Rachlla | A secondary axis of an inflorescence; e.g., the axis of the spikelet in Poaceae or the axis that bears the flowers in Arecaceae. |  |
| Radiate capitulum (head) | Inflorescence of Asteraceae with marginal ray flowers and central disk flowers. |  |
| Ramiflorous | Producing flowers on leafless branches or leafless parts of stems; a special type of cauliflory. Compare with cauliflorous. |  |
| Ramiflorous inflorescence | Refers to inflorescences that arise from the branches. Inflorescences that arise from the trunk are called cauliflorous. The branches can be much smaller in diameter than those shown here. |  |
| Ramifructus | Fruits born on the branches. | |
| Rhipidium (plural = rhipidia) | An alternately branching fan-shaped cyme with axes in one plane. | |
| Scorpioid cyme | A sympodial, determinate inflorescence whose lateral branches all develop from one side; it usually appears coiled and bears secund flowers. Same as bostryx. | |
| Solitary flower (inflorescence) | Referring to the presence of a single flower in an inflorescence. |  |
| Spadix (plural = spadices) | A congested spike with very small flowers that often is subtended by a spathe; e.g., the inflorescences of Araceae. |  |
| Spathe | A conspicuous bract that subtends or surrounds a spadix; in the Araceae, the lower part is called the tube and the upper part the blade; in Arecaceae the large, often woody bract derived from either the prophyll or peduncular bract. |  |
| Spicate | Referring to a spikelike inflorescence. | |
| Spike | An indeterminate, unbranched inflorescence with sessile flowers and the uppermost flowers the youngest. Compare with raceme. |  |
| Spikelet | A small secondary spike, such as the basic unit of the inflorescence of Cyperaceae and Poaceae; a spikelike branch of a compound inflorescence of the Bromeliaceae. | |
| Suprafoliar inflorescence | Referring to an inflorescences that arises from above the leaves. |  |
| Syconium (plural = syconia) | A hollow, fruitlike receptacle lined by tiny achenes, the characteristic inflorescence of figs (Ficus spp., Moraceae). Also called figs. |  |
| Syncephalous | Referring to an inflorescence of fused capitula. | |
| Synflorescence | A number of separate inflorescences clustered such that they appear as a single inflorescence; e.g., in Monotagma spp. (Marantaceae). | |
| Thyrse | An inflorescence in which the main axis is indeterminate and the lateral axes are determinate; i.e., a raceme of cymes. | |
| Thyrsiform | Like a thyrse. | |
| Umbell | A convex- or flat-topped inflorescence with all pedicels arising from the same point. |  |
| Umbellate | Like an umbel. | |
| Verticillaster | A pair of cymes arising from the axils of opposite leaves or bracts such that they falsely appear to be in a verticil; e.g., in some Acanthaceae and Lamiaceae. |
