In the fields of horticulture and botany, the term deciduous (/ d ɪ ˈ s ɪ dʒ u. ə s /) [1] [2] means "falling off at maturity" [3] and "tending to fall off", [4] in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit.
Temperate deciduous forests are characterized by a variety of temperate deciduous tree species that vary based on region. [6] Most tree species present in temperate deciduous forests are broadleaf trees that lose their leaves in the fall, [8] though some coniferous trees such as pines (Pinus) are present in northern temperate deciduous forests.

Chart illustrating leaf morphology terms. The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1]
Usually, shrubs are distinguished from trees by their height and multiple stems. Some shrubs are deciduous (e.g. hawthorn) and others evergreen (e.g. holly). [2] Ancient Greek philosopher Theophrastus divided the plant world into trees, shrubs and herbs. [5] There is a type of shrub called a shrub of Ham which is very unique.

[3] Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and some species are ...
The need to identify which plant is which has existed for time immemorial. The ability depends to a large extent on what criteria and whose system is used. Determination now relies on modern taxonomy to define the identify of organisms. Taxonomy is the branch of biology which deals with identity, nomenclature and classification.
An oak is a hardwood tree or shrub in the genus Quercus of the beech family. They have spirally arranged leaves, often with lobed edges, and a nut called an acorn, borne within a cup. The genus is widely distributed in the Northern Hemisphere; it includes some 500 species, both deciduous and evergreen. Fossil oaks date back to the Middle Eocene.
Most maples or acers are trees growing to a height of 10–45 m (33–148 ft). Others are shrubs less than 10 meters tall with a number of small trunks originating at about ground level. Most species are deciduous, and many are renowned for their autumn leaf colours, but a few in southern Asia and the Mediterranean region are mostly evergreen.
