1. Illegitimate Names: In taxonomy, an illegitimate name refers to a name that does not follow the rules and principles set by the International Code of Nomenclature for algae, fungi, and plants. Both scientific and non-scientific names can be illegitimate if they conflict with the rules, such as being previously used for another species or not being published with a correct description. 2. Description: In taxonomy, a description is a formal presentation of a new species in which the species' appearance, behavior, and other characteristics are detailed. It is a precise, scientific account including information like colors, shapes, sizes, habitat, and other distinguishing features, which is then verified through various specimens and observations. 3. Homonym: In the context of taxonomy, a homonym is a term used when the same scientific name is used to refer to more than one taxon. Homonyms can be of two types, either they are 'primary' (for identical names within the same kingdom) or 'secondary' (for identical names between kingdoms). 4. Nomenclature: In taxonomy, nomenclature refers to the system of assigning names to organisms. Taxonomic nomenclature specifically relates to the scientific naming of organisms according to international codes, which include the binomial nomenclature introduced by Linnaeus (Genus, species). 5. Systematics: This is the branch of biology that deals with classification and nomenclature of organisms. It involves organizing living organisms into groups or taxa, based on their similarities, differences, and evolutionary relationships. Systematics provides a system for identification, nomenclature, and classification of all living things. 6. Taxonomic Key: This is a tool used by scientists to identify, categorize and classify species of plants and animals. It often uses dichotomous choices (two distinct alternatives) that lead to the correct identification of the species. Taxonomic keys work by the process of elimination by offering paired statements (couplets) where one applies to the organism and the other does not.
