IMPARIPINNATE Meaning and
Definition
-
Imparipinnate is an adjective used to describe a specific arrangement of leaflets in a compound leaf structure. The term is derived from the Latin words "impar," meaning odd or uneven, and "pinnatus," meaning feathered or wing-like. In botany, it refers to a leaf that is composed of leaflets, with an odd number of leaflets arranged on either side of the central axis or midrib.
An imparipinnate leaf typically consists of a single large leaflet, known as the terminal leaflet, positioned at the end of the petiole or leafstalk. This terminal leaflet is often larger in size compared to the lateral leaflets. On either side of the terminal leaflet, a series of smaller leaflets are arranged in an alternate or opposite pattern. These smaller leaflets are attached to the central axis or rachis of the leaf and are usually symmetrical, with a mirror-like appearance.
Imparipinnate leaflets are commonly found in plants belonging to various families such as Fabaceae (legume family) and Meliaceae (mahogany family). Examples of plants with imparipinnate leaves include the horse chestnut (Aesculus hippocastanum) and the mimosa tree (Albizia julibrissin). The imparipinnate leaf arrangement is considered an important botanical characteristic used in plant taxonomy and identification.
In summary, imparipinnate refers to the arrangement of leaflets in a compound leaf structure, with an odd number of leaflets positioned on either side of a central axis or midrib.
