plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. it is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things).
plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. in practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. the precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed.
plant taxonomy is well known for being turbulent, and traditionally not having any close agreement on circumscription and placement of taxa. see the list of systems of plant taxonomy.
