A genus connects the bigger picture.

A genus is the level at which most field identifications start to feel precise. Botanists who recognise a genus from its leaves or fruit can often narrow a plant down to a handful of candidate species.

Scientific names follow international rules, so the same name refers to the same plant in Malaysia, Indonesia or anywhere else. Local names are valuable too, but one local name can cover several different species.

Writing a scientific name correctly

  1. Start the genus with a capital letter: Canarium.
  2. Write the specific epithet in lower case: Canarium odontophyllum.
  3. Set the whole name in italics, or underline it when writing by hand.
  4. After the first mention, the genus may be shortened to its initial: C. odontophyllum.

Parts of a name

Genus
The group of closely related species; the first word of the name.
Specific epithet
The second word, which picks out one species within the genus.
Binomial
The two words together: the species’ scientific name.

Naming rules: International Code of Nomenclature for algae, fungi, and plants.
