placentation |
|
CHARACTER |
|
Disposition of the placenta(e) within an ovary. |
fixation |
|
CHARACTER |
|
Mode of attachment to a supporting structure. |
base |
|
CHARACTER |
|
Configuration of the lowermost or proximal portion of a structure, its extent determined somewhat subjectively in relation to the shape of the structure as a whole. The concept of base varies from one descriptive context to another, since the base is not a clearly delimited, morphologically distinct entity. The terms for describing basal condition are not strictly coordinate logically — some are more inclusive than others, and some describe conditions involving what can be regarded as appendages — and precise characterization may require using more than one descriptor. The semantic antecedent of some descriptors is "base," whereas the antecedent of others is the structure as a whole (e.g., leaf ). |
duration |
|
CHARACTER |
|
Extent of lifetime, or persistence and physical state after maturation. |
prominence |
|
CHARACTER |
|
Elevation or depression of a discrete feature relative to the surrounding surface. |
arrangement |
|
CHARACTER |
|
Disposition of equivalent structures with respect to one another (positions/insertions and/or orientations, regarded collectively) within some explicit or implicit standard context. Overlaps conceptually with habit, insertion, orientation, position, and shape. |
plane shape |
|
CHARACTER |
|
Overall two-dimensional form or aspect(s) thereof. Overlaps conceptually with architecture, arrangement, habit, insertion, orientation, and position. |
extent |
|
CHARACTER |
|
Reach of the septum or septa within the ovary or fruit, relative to the ovary wall or pericarp and its center. |
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. |
location |
|
CHARACTER |
|
Position with respect to aspects of environmental context. |
germination 1 |
|
CHARACTER |
|
The process wherein a dormant embryo resumes active metabolism and growth, the primary root and shoot emerging from the seed coat, the young sporophyte thereupon entering the seedling stage. |
nutrition |
|
CHARACTER |
|
Mode of acquiring nutrients. |
germination 2 |
|
CHARACTER |
|
The process wherein the contents of a spore begin active growth, exiting the confines of the spore wall via a pore or crack and giving rise to a gametophyte. |
manifestation |
|
CHARACTER |
|
Degree or nature of evidence when present within the context in point. |
reflectance |
|
CHARACTER |
|
Aspect as to proportion and pattern of incident light reflected from the surface. |
coating |
|
CHARACTER |
|
Exudate that covers the surface proper. See also indumentum (vesture), pubescence. |
exudation |
|
CHARACTER |
|
Discharged substance, as to type. |
aestivation |
|
CHARACTER |
|
Disposition of perianth (undifferentiated), calyx, or corolla members in the bud. |
porosity |
|
CHARACTER |
|
Presence and disposition of vessels (pores) in wood (xylem). |
relief |
= sculpture |
CHARACTER |
|
General topographic aspect of a surface. Overlaps conceptually with solid shape. |
derivation |
|
CHARACTER |
|
Ontogenetic origin. |
size |
|
CHARACTER |
|
Nature as to absolute or comparative extent in any one dimension or in area or volume. |
venation |
|
CHARACTER |
|
Configuration of laminar vasculature as to its hierarchical organization and the dispositions of component orders. For descriptive purposes, the orders of vasculature are ranked with reference only to the lamina in point, irrespective of rank within any larger vascular context. |
margin |
|
CHARACTER |
|
Configuration of all or part of the periphery of a planate structure, sometimes referred to as though it were discrete and an entity in its own right for descriptive purposes. The extent of the area considered to pertain to the margin in a given case is, of necessity, subjectively determined. As a general rule, peripheral concavities that do not exceed 1/5 the distance from the generalized edge to the center or main axis of the structure are considered components of marginal configuration, deeper concavities being considered components of overall shape. The margin is sometimes considered to be only the infinitely thin boundary itself, and such a definition is probably the one most technically correct from the standpoint of geometry and general usage. However, it is inconsistent with traditional usage in descriptive botany, which treats the margin as an entity of substance both semantically and conceptually. The semantic antecedent of some descriptors is "margin," whereas the antecedent of others is the structure as a whole (e.g., leaf). |
odor |
|
CHARACTER |
|
Olfactory stimulation. |
