Rules of binomial nomenclature:
i. The name of the plant or animal is composed of two Latin or Greek words.
ii. Generic name is a simple noun which should come first and always begin with a capital letter.
iii. Specific name is the descriptive adjective which should come later and begin with a small letter.
iv. The names should be based on some special characters of the organism.
v. Usually the name of the author, who has named and described a plant or animal, is also written in full
or abbreviated form after the scientific name. e.g Mangifera indica L, where L stands for Linnaeus.
vi. The generic and specific name must be underlined separately if hand written or in italics when printed.
