Definition
Meaning
A dried plant or specimen preserved for scientific study.
Any dried biological specimen (especially botanical) used as a reference in scientific collections; a specific type of herbarium specimen.
Linguistics
Semantic Notes
Strictly a technical term from botany and taxonomy. While it refers to a dried specimen, the term itself is a noun, not a process. It belongs to a class of technical Latin-derived terms used in scientific nomenclature.
Dialectal Variation
British vs American Usage
Differences
No significant difference in usage. The term is equally rare and confined to specialist botanical/herbarium contexts in both regions.
Connotations
Neutral, purely denotative. Implies a specimen prepared to a formal standard for a scientific collection.
Frequency
Virtually never used outside professional botanical literature, museum catalogs, or historical texts on specimen collection.

Examples
By Part of Speech
verb
British English
- The botanist needed to exsiccate the moss carefully for the new exsiccatum.
American English

Learning
Memory Aids
Mnemonic
Think: 'EXit SICCAtum' – a plant has 'exited' its moist (siccus = dry) state to become a dried specimen.
Conceptual Metaphor
KNOWLEDGE IS A PRESERVED OBJECT (The preserved physical specimen embodies and fixes botanical knowledge for future reference.)
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque. In Russian botanical contexts, 'гербарный образец' or simply 'образец' is the standard term, not a Latinate equivalent of 'exsiccatum'.
- Do not confuse with general words for 'dry' or 'dried' (сухой, высушенный). It is a specific noun for a scientific object.
Common Mistakes
- Using it as a verb (to exsiccatum). The verb is 'exsiccate'.
- Using it in general contexts to mean 'something dried'.
- Misspelling as 'exiccatum' or 'exsicatum'.

FAQ
Frequently Asked Questions
No, it is an extremely rare technical term used almost exclusively by botanists, taxonomists, and historians of science.
Its core meaning is a dried plant specimen. By strict definition, it is botanical, though in very broad technical use it might be extended to other dried biological specimens, but this is uncommon.
The standard plural is 'exsiccata', following its Latin neuter plural form.
An exsiccatum is a scientifically prepared specimen, mounted and labelled with precise data (date, location, collector, species identification) for permanent reference in a formal collection like a herbarium. A simple dried flower lacks this scientific documentation and purpose.
