Flora

Simplified schematic of an island's flora - all its plant species, highlighted in boxes.

In botany, flora (plural: floras or florae) has two meanings. The first meaning, flora of an area or of time period, refers to all plant life occurring in an area or time period, especially the naturally occurring or indigenous plant life. The second meaning refers to a book or other work which describes the plant species occurring in an area or time period, with the aim of allowing identification. Some classic and modern floras are listed below.

The term flora comes from Latin language Flora, the goddess of flowers in Roman mythology. The corresponding term for animal life is fauna. Flora, fauna and other forms of life such as fungi are collectively referred to as biota.

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 an historic era as in fossil flora. Lastly, floras may be subdivided by special environments:

Bacterial organisms are sometimes included in a flora [1] [2], and sometimes the terms bacterial flora and plant flora are used separately.

Flora treatises

Traditionally floras are books, but some are now published on CD-ROM or websites. The area that a flora covers can be either geographically or politically defined. Floras usually require some specialist botanical knowledge to use with any effectiveness.

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.
