Classifications

Plants are grouped into floras based on region ( Phytochorion, floristic regions), period, special environment, or climate. Regions can be distinct

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: weedy species,
invasive species An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adv ...

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.
