Description
Return nominal and observed petal counts from whorl metadata.
Plant observations and seed or growth summaries depend on sampling area, observation time, material basis and inclusion policy. A local count or ratio can be consistent with the supplied records without estimating a complete population, establishing germination quality or identifying a growth mechanism.
Return nominal and observed petal counts from whorl metadata.
When to use this tool
Use Botanical Petal Count Whorl Budget when checking the stated botanical observation, seed, growth or coverage convention.
How to use the tool and how it works
- Enter whorls, nominalPerWhorl, missing, extra. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read expected, observed, discrepancy. Use the output convention below.
Return nominal and observed petal counts from whorl metadata. Require nonnegative whole whorls/nominalPerWhorl/extra and missing <= whorls*nominal; expected = product, observed = expected-missing+extra, discrepancy = extra-missing.1

}Limitations and assumptions
- This is a supplied count model, not image recognition, a species character diagnosis or proof of abnormal morphology.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified observations and an appropriate sampling, growth or material-balance model; assess uncertainty and biological meaning separately.
