CHARACTER |

|
pubescence |
|
CHARACTER |
|
Collective aspect of trichomes borne on the surface. Many of the terms traditionally used for describing pubescence have been defined and used in so many differing and often contradictory ways that they have become hopelessly ambiguous. This is attributable mainly to overdefinition within this portion of the traditional lexicon — that is, to highly arbitrary and widely variant restriction of a term's scope to some one detailed combination of trichome character states (shape, size, orientation, etc.). By derivation these are essentially general terms, really suited only for denoting overall aspect. The diversity actually encountered in nature defies comprehensive and unambiguous resolution into any limited suite of precisely specified, mutually exclusive, complex character states that can be associated with these terms, which are best used only in their general senses. Sometimes, such description will be sufficient in itself; more often, additionally or alternatively, the various attributes of the individual trichomes should be described. This is the only strategy that allows for full description of any possible condition, including the presence of more than one type of trichome. The various terms used for describing pubescence have never been semantically consistent; in some cases they refer to the trichomes themselves, while in others they apply to the bearing surface or structure; e.g., sericeous (the trichomes themselves are collectively silky) versus barbate (the structure is bearded). See also coating, indumentum (vesture). |
|
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 ). |
|
habit |
|
CHARACTER |
|
General appearance and/or function, usually including explicit or implicit reference to one or more aspects of habitat or other features of the external environment; a logically imprecise traditional category of terms that overlaps conceptually with architecture, arrangement, duration, insertion, location, orientation, position, shape, and texture. |
