|
palea 2 pl. paleae, paleas |
= pale, palet |
STRUCTURE |
|
The distal bract of the (usually) two that immediately subtend the flower in a grass (Poaceae) spikelet; the other is the lemma. |

STRUCTURE |
|
A small papery (chartaceous) to membranous bract borne on the compound receptacle (torus) of a capitulum (head) in Asteraceae (Compositae). |
|
pale 2 |
= palea, palet |
STRUCTURE |
|
The upper or distal of the (usually) two distinctive bracts immediately subtending the flower in a grass (Poaceae) spikelet. |
|
pale 1 |
= palea, palet, receptacular bract |
STRUCTURE |
|
A small papery (chartaceous) to membranous bract borne on the compound receptacle of a capitulum (head) in Asteraceae (Compositae). |
|
palate |
|
STRUCTURE |
|
The lower, prominent labium (lip) of a personate (gaping, ringent) corolla. |
|
palaceous |
|
architecture |
foliaceous structure |
Having the petiole attached to the abaxial face of the blade at some point within the margin and adnate to it from there to the margin, thus peltate but with the distal portion of the petiole adnate to the blade, the whole shovel- or spade-like. |
|
paired |
= conjugate, geminate |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
|
pachycaulous |
|
architecture |
plant |
Having thick, more or less succulent stems. |
|
ovuliferous scale |
< cone scale, macrosporophyll (not recommended), megasporophyll |
STRUCTURE |
|
A fertile scale in a female cone (megastrobilus), bearing one or two naked ovules, and subsequently seed(s), subtended by and borne closely upon a sterile, fleshy or woody scale sometimes termed a bract scale; in Pinophyta. |
|
ovule |
|
STRUCTURE |
|
A complex reproductive structure borne by a seed-plant sporophyte, consisting of outer, sporophytic tissues that enclose a haploid, gametogenic tissue usually regarded as a highly reduced megagametophyte. Following fertilization, the entire structure matures to become a seed that contains an embryo, the first stage of the next sporophytic generation. Ovules (and seeds) are borne naked on megasporophylls (in Pinophyta) or within an ovary (in Magnoliophyta). |
|
ovoid |
= egg-shaped |
solid shape |
|
Transversely circular, broadest near a bluntly rounded base, and convexly attenuate to a narrower rounded apex; like a fowl egg. See also obovoid. |
|
overlapping 2 |
= imbricate(d) |
arrangement |
planate structures |
Overlapping one another laterally and/or longitudinally. |
|
overlapping 1 |
= imbricate(d) |
aestivation |
|
Having members whorled or spirally inserted and overlapping one another, each overlapping or overlapped to either side, and also above or below if spirally arranged or in multiple whorls. |
|
ovate |
= egg-shaped |
plane shape |
|
Elongate and wholly convex, widest near a bluntly rounded base and attenuate to a narrower rounded apex; like the lateral outline of a fowl egg. See also obovate. |
|
ovary |
|
STRUCTURE |
|
The proximal portion of a pistil (either simple or compound) within which the ovules are borne; usually of somewhat greater diameter and/or volume than the remainder of the pistil. |
|
oval |
= elliptic(al) |
plane shape |
|
Elongate, widest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
|
ostiole |
|
STRUCTURE |
|
The distal aperture of a syconium (fig); in Ficus (Moraceae). |
|
osseous |
= bony |
texture |
|
Very hard and rather brittle, like bone. |
|
orthotropous |
= atropous |
orientation |
ovule |
Having the (straight) ovule sessile or funiculate and divaricate, the micropyle facing away from the ovary wall (placenta). |
|
orientation |
|
CHARACTER |
|
Attitude or direction with respect to some explicit or implicit structure(s) or context. The lexicon relating to orientation includes some conceptually complex terms whose meanings also embrace aspects of structural composition or shape. Overlaps conceptually with arrangement, habit, insertion, position, and shape. |
|
orbiculate |
= round; orbicular misapplied |
plane shape |
|
Circular. |
|
orbicular |
= globose, globular, rotund, spheric(al), spheroid(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a sphere or globe. |
|
opposite 2 |
|
arrangement |
|
Having the members of each whorl inserted directly above and/or below those of the next adjacent whorl(s). See also antipetalous, antisepalous. |
