Plant taxonomists are scientists who have been trained in any plant diversity discipline to discover and provide responses to the following questions :

• How can plants be recognized? (Identification);
• With what name should plants be called so that their information can be freely exchanged without ambiguity? (Nomenclature);
• Which are their closest relatives? Are there any other similar plants or do they have similar properties, or compatible genetic systems? (Classification);
• Where and how can they be found? (Ecology-Biogeography);
• Do they show any property that can be used? (Resource management);
• What is the population size of a specific taxon? (Ecology and Conservation).

The taxonomist should have the abilities to collect, preserve samples, gather information and analyze data to achieve the adequate identification. The specialist should also have aptitudes to do exploration work in the field, to climb mountains, camp for several days in cold and hot weather and little food, know how to live in harmony with country people, etc, etc. The exact name of the organism is the key for ALL that needs to be told or written about the species it belongs to. Due to the complexity of the nomenclature, the International Code of Botanical Nomenclature ruling this aspect was created. The essential tools of a taxonomist are the herbarium specimens, a microscope, botanical literature, and specialized colleagues in taxonomical groups who work in other herbariums in the country or abroad.
