Troglodytarum alpinum

A sketch of a Mountain Troll, by Newt Scamander, labelled with its proper scientific name, Troglodytarum alpinum

"She lingered in that charming little garden to say hello to the gnomes, such a glorious infestation! How few wizards realise just how much we can learn from the wise little gnomes — or, to give them their correct name, the Gernumbli gardensi."
Xenophilius Lovegood at Bill and Fleur's wedding[src]

Taxonomy is the science of defining and naming groups of biological organisms on the basis of shared characteristics. Organisms were grouped together into taxa and these groups were given a taxonomic rank, creating a hierarchy: the principal ranks in use in the 21st century were (in descending order) kingdom, phylum, class, order, family, genus and species.

Wizarding species

Wizarding creatures and plants were also subject to taxonomic classification:

  • Trolls are grouped together in the Troglodytarum genus. Individual species include the Mountain Troll (Troglodytarum alpinum) and the Forest Troll (Troglodytarum sylvaticum).[1]
  • Urtica diocia is the taxonomic name of the stinging nettle, or burn hazel, used in potion-making.[4]

Behind the scenes

  • Falco aesalon is the name given by English ornithologist Marmaduke Tunstall in 1771 to the Eurasian merlins, which he considered a different species from the North American kind, Falco columbarius (it is still not completely resolved if the two are different species or not). In the Harry Potter universe, Falco Aesalon was the name of an Ancient Greek wizard who, appropriately enough, could turn into a falcon at will, being the first Animagus on record.
