Classifications

Plants are grouped into floras based on region ( Phytochorion, floristic regions), period, special environment, or climate. Regions can be distinct
habitat In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical ...
s 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:
weed A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place", or a plant growing where it is not wanted.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24. ...
y 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

Often these are ''dichotomous'' keys, which require the user to examine a plant repeatedly, and decide which one of two alternatives given best applies to the plant.
