zuzu said:... Sprengel then described it again in 1826. Sprengel's is listed as an illegitimate name (nom. illeg.) because the name was already published by Nuttall.
Thank you for the term "illegitimate name"!
It led me to all these very valuable terms of art. Now I have Latin names ... for Latin names!

"
Nomen illegitimum (Latin for illegitimate name) is a technical term, used mainly in botany. It is usually abbreviated as nom. illeg."
(Unlike names written in Magic Marker on polyethylene plastic: nomina illegibilii.)

" ambiguous names,
nomina ambigua, have been used with more than one meaning
names causing confusion,
nomina confusa, are based on a mixed culture
perplexing names,
nomina perplexa, confusingly similar names
perilous names,
nomina periculosa, names that may lead to accidents endangering life or health or with potential serious economic consequences
In botanical nomenclature the phrase
nomen dubium has no status, although it is informally used for names whose application has become confusing. In this regard however, its synonym nomen ambiguum is of more frequent use."
