| Term | Synonyms | Category | Limitation | Definition |
|---|---|---|---|---|
| pulverulent | = granuliferous, powdery | coating | Covered with a more or less even deposit of fine, dry particles. See also lentiginous (dusty, lentiginose), which is not clearly distinct in its application. | |
| pulvinate 1 | architecture | inflorescence axis, petiole | Having a pulvinus. | |
| pulvinate 2 | = cushion-shaped, mound-shaped, pulviniform | solid shape | Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface. | |
| pulviniform | = cushion-shaped, mound-shaped, pulvinate | solid shape | Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface. | |
| pulvinus pl. pulvini | STRUCTURE | A short, cushion-like swelling at the junction of stem and leaf or of inflorescence axis and branch. | ||
| punctate 1 | = dotted | coloration | Having small, round, clear or colored spots that contrast with the ground color. See also puncticulate (small-dotted). | |
| punctate 2 | = dotted | relief | Having small, round, shallow depressions or low protrusions. See also puncticulate (small-dotted). | |
| puncticulate | = small-dotted | coloration | Finely punctate (dotted). | |
| puncticulate | = small-dotted | relief | Finely punctate (dotted). | |
| punctiform | = dot-like | plane shape | Very small and generally circular in outline. | |
| punctum pl. puncta | = dot | FEATURE | A small, generally round sector of distinct coloration or relief. | |
| pungent 1 | = acrid | apex | Terminating abruptly in a rigid, relatively short, sharp point composed of both vascular and laminar tissues. | |
| pungent 2 | = acrid | odor | Sharp or astringent. | |
| pustulate | = blistered, bullate, puckered | relief | Having relatively coarse, irregularly disposed, rounded protrusions or convexities resembling blisters. See also papillate, papillose. | |
| pustule | = blister, bulla | FEATURE | A relatively coarse, rounded protrusion or convexity. See also papilla. | |
| putrid | = fetid | odor | Stinking like rotting flesh. | |
| pyramidal | solid shape | Transversely triangular or polygonal, broadest at the base and regularly attenuate to an angular apex, all faces essentially plane. | ||
| pyrene 1 | = stone | STRUCTURE | The hard inner portion of a drupe, consisting of osseous endocarp and included seed. | |
| pyrene 2 | = stone | STRUCTURE | The hard seed of a drupelet; esp. in Rosaceae. | |
| pyriform | = pear-shaped | solid shape | Basically circular in transverse section, broadest toward one end, attenuate toward and much narrower at the other, both ends rounded; slenderly turbinate or obturbinate; like a pear. | |
| pyxis pl. pyxides | nominative | fruit | Like a capsule but circumscissile, the one or more seeds being released from the locule(s) upon separation of the distal, cap-like portion of the pericarp. See also diplotegium. | |
| quadr(i)… | = four-…, tetra… | prefix | Indicating presence of or constitution by four entities of the type denoted by the term's stem; as in quadrangular, quadrilocular. | |
| quincunx | aestivation | Imbricate in one whorl of five members, two wholly exterior, two wholly interior, and one partially exterior and partially interior. | ||
| raceme | nominative | inflorescence | An elongate, unbranched main axis bearing pedicellate flowers inserted singly along it. | |
| raceme-like | = racemiform | architecture | capitulescence, inflorescence | Resembling a raceme, but not strictly such. |
