Is it Carpinus turczaninowii or turczaninovii ?

This is what ChatGPT tells us (dated 20260604):
'The currently accepted botanical name is Carpinus turczaninovii — with "ovii", not "owii". Multiple modern taxonomic references use Carpinus turczaninovii Hance as the correct name.

The confusion comes from the species being named after the botanist Nikolai Turczaninov. His surname has been transliterated both as Turczaninov and Turczaninow in different languages, which led many horticultural sources to use the spelling "turczaninowii". However, the original published species epithet was turczaninovii, and that is the accepted scientific name today.

So:

  • Carpinus turczaninovii — accepted scientific name
  • ⚠️ Carpinus turczaninowii — common alternative spelling found in horticultural literature and some garden databases, but generally treated as a variant spelling/synonym rather than the accepted name.

If you're preparing a botanical label, herbarium record, paper, or plant database entry, use Carpinus turczaninovii."
