Flora, manuals, monographs and catalogues are some of the taxonomic aids.
(i) Flora contains the useful account of habitat and distribution of plants of a given area. These provide the index to the plant species found in a particular area.
(ii) Manuals are useful in providing information for the identification of names of species found in an area.
(iii) Monographs contain all the information about a particular taxon.
(iv) Catalogue is a list that enumerates all the species found in a particular area.
