Taxonomical aids are defined as the collection of the prime sources of various species of plants, animals and other organisms, which help in their classification, identification and study of the bio-resources. Biologists worldwide have established certain procedures and techniques that help in collecting and storing the data of specimens of the organisms.


Plant specimens are preserved by drying leaves and pressing them on sheets. These sheets along with specimens and their description are arranged according to universally accepted system of classification and placed in a store house called herbarium. The herbarium sheets carry information like date and place the specimen was collected, English, local and botanical names, family, collector’s name etc. These herbarium sheets provide a quick reference to taxonomical studies.
