The first word in a biological name represents the genus while the second component denotes the specific epithet. Both the words in a biological name, when handwritten are separately underlined or printed in italics to indicate their Latin origin. The first word denoting the genus starts with a capital letter while, the specific epithet starts with a small letter, e.g., Mangifera indica
