Plant taxonomy is the science that finds, describes, classifies and names plants. It thus is one of the main branches of taxonomy. Example for the Liliales order : Divisions Land plants (embryophytes) Non-vascular plants (bryophytes) Marchantiophyta - liverworts Anthocerotophyta - hornworts Bryophyta - mosses Vascular plants (tracheophytes) Lycopodiophyta - clubmosses Equisetophyta - horsetails Pteridophyta - true ferns Psilotophyta - whisk ferns Ophioglossophyta - adderstongues Seed plants (spermatophytes) †Pteridospermatophyta - seed ferns Pinophyta - conifers Cycadophyta - cycads Ginkgophyta - ginkgo Gnetophyta - gnetae Magnoliophyta - flowering plants Adiantum pedatum (a fern...

There is no sharp boundary between "plant taxonomy" and "plant systematics", although in practice "plant systematics" will be involved with higher level relationships between plants (see history of plant systematics) rather than with the actual handling of plants (see herbarium). Plant taxonomy is wellknown for being turbulent, and traditionally there is no really close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy. Classes Magnoliopsida - Dicots Liliopsida - Monocots The flowering plants (also angiosperms or Magnoliophyta) are one of the major groups of modern plants, comprising those that produce seeds in specialized reproductive organs called flowers, where the ovulary or carpel is enclosed. ...

A history of plant systematics should either start with folk taxonomy or with Theophrastus’s Historia Plantarum, the first scientific treatise published on plants. ... In Botany, a herbarium is a collection of preserved plants or plant parts, mainly in a dried form. ... A taxon (plural taxa), or taxonomic unit, is a grouping of organisms (named or unnamed). ...
