A floral diagram is a graphic representation of the structure of a flower. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification or can help in understanding angiosperm evolution.
The need to identify which plant is which has existed for time immemorial. The ability depends to a large extent on what criteria and whose system is used. Determination now relies on modern taxonomy to define the identify of organisms. Taxonomy is the branch of biology which deals with identity, nomenclature and classification.
The number of stamens may or may not be equal to the number of petals. Thus, the flower is said to be isostomous if it has the same number of stamens as petals (as can be seen in the liliaceae and amaryllidaceae); anisostomous if the number of petals is different from the number of stamens (for example, in the genus Brassica, there are four ...
A pioneering system of plant taxonomy, Linnaeus's Systema Naturae, Leiden, 1735. This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A taxonomic system is a coherent whole of taxonomic judgments on circumscription and placement of the considered taxa. It is only a "system" if it is applied to a ...
In plant taxonomy, which is the study of the classification and identification of plants, the morphology of plant's flowers are used extensively – and have been for thousands of years. Although the history of plant taxonomy extends back to at least around 300 B.C. with the writings of Theophrastus , [ 124 ] the foundation of the modern ...

Plant identification is a determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification manuals. The process of identification connects the specimen with a published name. Once a plant specimen has been identified, its name and properties are known.
In 2002 Plantlife conducted a "County Flowers" public survey to assign flowers to each of the counties of the United Kingdom and the Isle of Man. [1] The results of this campaign designated a single plant species to a "county or metropolitan area" in the UK and Isle of Man. [2] Some English counties already had flowers traditionally associated with them before 2002, [3] and which were ...
