compressed |
= complanate; < flattened |
solid shape |
|
Flattened bilaterally, parallel to the longitudinal axis, as though pressed or squeezed from opposing sides, the external surface otherwise basically convex. Used alone, this term usually implies a strong degree of flattening; otherwise, it is often used in combination with some other term that describes the overall shape exclusive of ("before") flattening, e.g., compressed-ovoid. See also depressed, obcompressed. |

STRUCTURE |
|
A second- or higher-order division or leaflet of a pinnate frond; a division of a pinna; in Polypodiophyta. |

FEATURE |
|
A small, generally round sector of distinct coloration or relief. |

Upon or otherwise directly associated with the stamens. |
|
hood-shaped |
= cucullate, cuculliform |
solid shape |
|
Convex or compressed-convex overall with a distal peak or ridge, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a hood or cowl. See also helmet-shaped (galeate, galeiform), which overlaps conceptually. |
|
surface |
|
FEATURE |
|
The exterior or bounding area or layer of any structure, regarded as being infinitely thin; usually described as to relief, reflectance, and/or vesture. |
|
labellum pl. labella |
< labium, lip |
STRUCTURE |
|
The third petal of a tripetalous flower when distinctively different from the other two, usually enlarged relative to them and/or differently shaped or colored, usually apparently the abaxial (lower) petal of the three due to resupination during ontogenesis; esp. in Orchidaceae. |
|
trumpet-shaped |
= tubiform |
solid shape |
|
Obteretely tubular with a relatively short distal flare (the limb if a perianth, calyx, or corolla). |
|
balding |
= glabrescent |
pubescence |
|
Becoming bald (glabrous, psilate) with age. |
|
micropyle |
|
FEATURE |
|
The small pore in the integuments of an ovule at its apex, through which the pollen tube grows; or the corresponding aperture or scar in the coat of the seed that develops subsequently. |
|
androecial tube |
|
STRUCTURE |
|
The tubular portion of an androecium in which the component structures have fused with one another laterally over part or all their lengths. |
|
banded |
|
coloration |
|
Broadly striped; having one or more elongate, relatively broad and, when multiple, more or less parallel, areas of contrasting hue and/or intensity. |
|
microsporangium pl. microsporangia |
|
STRUCTURE |
|
A sporangium that produces microspores. |
|
calyptriform |
|
solid shape |
|
Hollow, roughly circular in cross-section, broader and open distally, and tapering to a closed apex, like a candle snuffer or elongate hood. |
|
oil-secreting |
|
exudation |
|
Producing and exuding an oily substance, often aromatic; when oil-secreting glands are indicated in the nominative, often they are called simply oil glands. |
|
cochleate |
= snail-shell-shaped |
solid shape |
|
Relatively broad and short, basically round in transverse section, resembling a rapidly tapering spire overall, the exterior helically convoluted; like a snail shell. |
|
perisperm |
|
STRUCTURE / SUBSTANCE |
|
A genetically diploid (2n chromosomes) nutritive tissue in a seed; containing stored carbohydrate and/or oil utilized by the embryo prior to and especially upon germination; derived from the nucellus. See also endosperm (albumen). |
|
crustaceous |
= crusty |
texture |
|
Thin, dry, hard, and brittle. |
|
proximal |
> basal |
position |
|
Upon or associated with the portion of a structure closest to its developmental origin. |
|
dorsifixed |
|
fixation |
|
Attached on the abaxial side well above the base. |
|
ribbed 2 |
|
solid shape |
|
Having two or more prominent, elongate, relatively narrow, essentially parallel protrusions that extend over all or most of its length or circumference. |
