Flora (plants)

For other uses, see Flora (disambiguation).


Flora is the plant life occurring in a particular region or time, generally the naturally occurring or indigenousnative plant life. The corresponding term for animal life is fauna. Flora, fauna and other forms of life such as fungi are collectively referred to as biota. Bacterial organisms, algae, and other organisms are sometimes referred to as flora,[1][2][3] so that for example the terms bacterial flora and plant flora are used separately.

Etymology

"Flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology.

Flora classifications

Plants are grouped into floras based on region, period, special environment, or climate. Regions can be geographically distinct habitats like mountain vs. flatland. Floras can mean plant life of a historic era as in fossil flora. Lastly, floras may be subdivided by special environments:

  • Native flora. The native and indigenous flora of an area.
  • Agricultural and Horticultural flora (garden flora). The plants that are deliberately grown by humans.
  • Weed flora. Traditionally this classification was applied to plants regarded as undesirable, and studied in efforts to control or eradicate them. Today the designation is less often used as a classification of plant life, since it includes three different types of plants: weedy species, invasive species (that may or may not be weedy), and native and introduced non-weedy species that are agriculturally undesirable. Many native plants previously considered weeds have been shown to be beneficial or even necessary to various ecosystems.

Flora treatises

Main article: Flora (publication)



A flora treatise (usually simply known as a Flora), requires specialist botanical knowledge to use with any effectiveness. Traditionally flora treatises are books, but some are now published on CD-ROM or websites.

It is said that the Flora Sinensis by the Polish Jesuit Michał Boym was the first book that used the name "Flora" in this meaning, a book covering the plant world of a region.[4] However, despite its title it covered not only plants, but also some animals of the region.

A flora often contains diagnostic keys. Often these are dichotomous keys, which require the user to repeatedly examine a plant, and decide which one of two alternatives given in the flora best applies to the plant.

A compendium of world floras has been compiled by David Frodin.[5]
