Flora

Flora is the plant life occurring in a particular region or time, generally the naturally occurring or indigenous—native 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. Sometimes bacteria and fungi are also referred to as flora, as in the terms gut flora or skin flora.

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 people.

 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.
