The collection of the prime sources of various species of plants, animals and other organisms, which help in their classification and identification, is known as taxonomical aid.
For the identification of species and their placement in taxanomical hierarchy, both laboratory and field studies are important. The information gathered about species is stored. Also, specimens are actually collected, preserved and stored for verification if need later on. Herbarium, museum, zoological park, key and botanical garden are several aids which help in taxonomic studies.
