Answer
Publications of Carolus Linnaeus' binomial system. The rules are as follows:
(1) Biological names are generally in Latin and written in italics. They are Latinised or derived from Latin irrespective of their origin.
(2) The first word in a biological name represents the genus while the second component denotes the specific epithet.
(3) Both the words in a biological name, when handwritten, are separately underlined, or printed in italies to indicate their Latin origin
(4) The first word denoting the genus starts with a capital letter while the specific epithet starts with a small letter. It can be illustrated with the example of Mangifera indica.
Name of the author appears after the specific epithet, i.e., at the end of the biological name and is written in an abbreviated form, e.g., Mangifera indica Linn. It indicates that this species was first described by Linnaeus.
