Binomial System for Nomenclature

 The scientific name of a plant consists of two words written in
Italics.

 The first name is the generic (Genus) beginning with a capital letter
e.g. Atropa, Linum, Rhamnus. It may be abbreviated to its first
(capital) letter.

 The second is the specific name (Species) beginning with a small
letter that never used by itself. Atropa belladonna A. belladonna

 It is more complete to place the surname of the person who first
named the species after its specific name. Atropa belladonna L.
(For Linnaeus).
