Pampas	A Spanish term referring to grass-dominated plains, especially those found in eastern Argentina.

Papilionoid	Referring to flowers similar to those of Fabaceae subfamily Papilionoideae; e.g., those of the Polygalaceae.
Papilla (plural = papillae, adj. = papillate)	Small projections that are often found on leaf blade surfaces. Papillae usually represent modifications of the cuticle.
Papilla (plural = papillae; adj. = papillate)	Referring to an abaxial leaf blade surface or a stigma that bears minute protuberances that appear to be outgrowths of the cuticle of the leaf blade or of the stigma.
Papillae	Minute, rounded protuberances that may cover a surface, e.g., the abaxial leaf blade surfaceae.

Paracytic stomata	Referring to a stomatal type in which the two subsidiary cells are parallel to the long axis of the guard cells. The brachyparacytic type is the same as the paracytic type.
Paracytic stomata	Referring to a stomatal type in which the two subsidiary cells are parallel to the long axis of the guard cells. The brachyparacytic type is the same as the paracytic type.
Parallel venation	Generally applied to secondary or higher-order veins that are parallel to each other and to the margins of the leaf, sepal, or petal in which they occur but in monocots they are often numerous primary veins of the same size.
Parallelodromous	Referring to a leaf venation in which there are multiple parallel primary veins that originate at the leaf blade base and converge toward the leaf blade apex. Mostly restricted to monocotyledons. See Ellis et al. 2009 for more detailed descriptions of leaf characters.
Páramo	A Spanish term referring to a high-elevation, humid, Andean vegetation ranging from Venezuela to northern Peru.
Paraphyletic	A taxonomic group encompassing some but not all of the descendants of its most recent common ancestor.

Parasite (parasitic)	An organism that obtains its nutrition entirely (e.g., Helosis cayennensis) or partly (e.g., Loranthaceae) from other plants.
Parenchyma	Ground tissue composed of mostly isodiametric, thin-walled cells that usually retain the ability to divide.
Parietal placentation	A type of placentation found in compound, unilocular ovaries in which the ovules arise from placentae inserted on the wall of the locule near the sutures.
Paripinnada	Dos veces pinnada; por ejemplo, las hojas de muchas especies de Fabaceae-Mimosoideae. Ver pinnada
Paripinnate leaf	Pinnate with an even number of leaflets; i.e., without a terminal leaflet. Same as even-pinnate and parapinnate..

Patelliform	Shaped like a kneecap; e.g., the glands of some species of Diospyros (Ebenaceae).
Patent	Spreading.
Pearl bodies	Glycogen-rich food bodies on the surfaces of the leaves of species of Pourouma (Cecropiaceae). Compare with Muellerian bodies.
Peciolo	Rabillo que une a la lámina de una hoja con el tallo o rama; en las hojas compuestas es el rabillo que está entre la inserción de la hoja en el tallo o rama y el par basal de foliolos
Peciólulo	Peciolo que sostiene a la hojuelas en las hojas compuestas. Hay varios órdenes de peciólulos en las hojas que son dos o más veces compuestas. En las hojas palmeadas-compuestas los peciólulos están dispuestos de manera radial desde un punto central
Peconha	For trees smaller than ten centimeters in diameter, a climber can use an adjustable loop called a peconha in Brazilian Portuguese. A peconha was traditionally made of bark fiber, but is now made of canvas.The climber places it around his feet, grips the tree with both hands and his looped-together feet, and essentially hops up the tree.

Pectinate	Pinnately divided into many more or less parallel segments and resembling the teeth of a comb.
Pedaliform	Resembling the sole of a foot in shape.
Pedate	Palmately divided with the lateral divisions 2-cleft.
Pedatisect	Pedately divided with the sinuses nearly reaching the middle. Compare with pedate.
Pedicel	The stalk of the flower. Flowers without pedicels are called sessile.
Pedicel (adj. = pedicellate)	The stalk supporting some flowers.
Pedicel scar	The scar left by the stalk to which the fruit is attached.
Pedicel/hypanthium	The pedicel is articulate in all species of Lecythidaceae. In some species the hypanthium tapers to the articulation and resembles a pedicel and, in other species, the hypanthium is truncate and does not resemble a pedicel. Thus, everything from the calyx to the articulation and from the articulation to the rachis is called the pedicel/hypanthium.
Pedicel/hypanthium tapered to articulation	The pedicel/hypanthium is tapered gradually to the ariculation such that a true pedicel appears to be present
Pedicel/hypanthium truncate at articulation	There is no clear cut pedicel in this type of pedicel/hypanthium
Pedicelo	Estructura usualmente linear u oblonga que sostiene a la flor
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.
