In botany, flora (plural: floras or florae) has two meanings.

The first meaning  refers  Flowers ,Flower Goddess and plant life in an area or time period (especially the naturally occurring or indigenous plant life). The corresponding term for animal life is fauna.

The second meaning refers to a book or other work which describes the plant species in an area or time period, with the aim of allowing identification.

The term flora comes from the Latin language. Flora was the goddess of flowers in Roman mythology.

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 an historic era as in fossil flora.

Bacterial organisms are sometimes included in a flora    . Other times, the terms bacterial flora and plant flora are used separately.
