The first scientific attempt to name the organism was polynomial nomenclature which consisted of number of words that incorporate all its important characters. E.g.: Caryophyllum was named as Caryophyllum saxatilis folis gramineus umbellatis corymbis, which means caryophyllum growing on rocks having grass like leaves and umbellate corymb arrangement of flowers. However polynomial system of nomenclature was not favoured by many scientists as it is difficult to remember long descriptive names. To over come this problem a system was developed by Carolus Linnaeus known as “Binomial nomenclature”. This system provides organisms with appropriate and distinct names consisting of two words, the generic name and the specific epither E.g. potato is named as Solanum tuberosum. Solanum represents genus and tuberosum species. The first name or genus begins always with a capital letter and second or species name with small letter, and both are separately underlined, when written and italicised when printed.
