|
papilionaceous |
= butterfly-like |
architecture |
corolla |
Having a relatively large, erect adaxial (upper) petal (the standard, banner or vexillum), two smaller lateral petals (the wings or alae), and two individually smaller but connate or coherent abaxial (lower) petals that together form a carinate structure (the keel or carina), the whole loosely resembling a butterfly with wings spread. |
|

|
FEATURE |
|
A small, conoidal protrusion resembling a pimple. See also pustule (blister, bulla). |
|
papillar(y) |
= papilliform |
solid shape |
|
Small, conoidal, and protruding from a larger structure; resembling a pimple; esp. trichomes. |
|
papillate |
= papillose |
relief |
|
Having small, conoidal protrusions overall; appearing pimply. |
|
papilliform |
= papillar(y) |

|
pappose |
|
architecture |
flower, fruit |
Bearing a pappus; esp. in Asteraceae (Compositae). |
|
pappus pl. pappi |
|
STRUCTURE |
|
A set of one or more awns (aristae, bristles, setae) or scales at the summit of an inferior ovary just beneath or outside the free portion of the corolla; persisting in the fruit (cypsela) and often aiding wind or animal dispersal; in Asteraceae (Compositae). Considered by some to be an evolutionarily modified upper calyx portion, the lower portion having been incorporated into the floral tube casing adnate to the ovary wall; considered by others to be an outgrowth from the ovary wall. |
|
pappus scale |
|
STRUCTURE |
|
A pappus element that is more or less planate and relatively thin and broad; may terminate in one or more awn- or bristle-like appendages. |
|
papyraceous |
= chartaceous, papery |
texture |
|
Very thin, flexible, and readily torn; like paper. See also membranaceous (membranous), pergamentaceous (parchment-like). |
|
paracytic |
= rubiaceous |
architecture |
stomate |
Having one or more subsidiary cells to either side, all oriented parallel to its long axis. |
|
parallelodromous |
|
venation |
|
Having two or more primary veins that run more or less parallel to one another over most of the laminar length and converge near the apex. |
|
paraphysis pl. paraphyses |
|
STRUCTURE |
|
An elongate, multicellular, sterile structure borne between sporangia within a sorus; in Polypodiophyta. |
|
parasitic |
|
nutrition |
plant |
Heterotrophic and obtaining essential nourishment directly from other living organisms that derive no reciprocal benefit. |
|
parchment-like |
= pergamentaceous |
texture |
|
Very thin, pliable, and fairly tough; like parchment. See also chartaceous (papery, papyraceous), membranaceous (membranous). |
|
parietal |
|
placentation |
|
Upon the inner wall surface of a unilocular ovary, thus peripheral within the locule. |
