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 ). |
