Decidue

Decidue is a term that appears sporadically in botanical and biological writings, but it does not have a fixed, widely accepted definition in modern scientific usage. It is not listed in major English dictionaries, and when encountered it is typically described as an archaic, regional, or contextual variant related to the concept of shedding or falling off.

Definitions and scope

In some historical or niche contexts, decidue is presented as an adjective or noun resembling deciduous in referring to parts of an organism that detach or shed—such as leaves, tissues, or other structures—in response to seasonal or environmental cues. In contemporary practice, however, standard terms such as deciduous, abscission, or molting are preferred, and decidue is often treated as obsolete or non-standard.

Etymology

The form decidue is generally linked to the Latin deciduus, meaning falling off. The term may emerge through truncation, regional spelling, or stylistic variation, rather than as a recognized instrument of current taxonomy or morphology.

Usage and status

Decidue remains rare and largely undocumented in current scientific nomenclature. When it appears, it is typically within historical texts, regional writings, or speculative literature, where its exact meaning should be inferred from the surrounding context.
