Generic name is a singular noun and begins with a capital letter. All

names up to this rank are single word (i.e., Uninomial or Unitary) and are

written in italics in print: Example: Lilium, Digitalis.

Naming of Species: The name of species consists of two words:

◦ First name is the generic name.

◦ Second name is the specific epithet. The second name is never used alone.

◦ The surname of the person, who first named the plant (Author), has to be placed

after the specific epithet.
