What is a type specimen?

It is the specimen selected by a botanist as an example of a particular species (and/or category of plants). Current international rules of naming plants require that a new name of a newly discovered species is supported by a type specimen in a recognized collection. The type is frequently the most clear indication of what a plant name represents and types are often examined so that plant names can be properly applied.

Several kinds of types are officially recognized in the International Code of Botanical Nomenclature
