ALNUS JORULLENSIS Meaning and
Definition
-
Alnus jorullensis, commonly known as Mexican alder or evergreen alder, is a tree species native to Mexico and Central America. It belongs to the family Betulaceae and is characterized by its rapid growth and tolerance to various environments. The species name "jorullensis" is derived from the Jorullo volcano in Mexico, where the tree was first discovered.
Mexican alder is a deciduous tree that can reach heights of up to 30 meters (98 feet) and has a spreading, symmetrical crown. Its leaves are dark green, alternate, serrated, and usually elliptical or oval-shaped. The bark is smooth and grayish when young, developing shallow fissures and becoming darker with age.
This tree is primarily found in riparian habitats, such as riverbanks and wetlands, where it plays a vital role in preventing soil erosion. The root system of Alnus jorullensis is characterized by nodules that contain nitrogen-fixing bacteria, allowing it to convert atmospheric nitrogen into a usable form for itself and surrounding plants. This ability helps improve soil fertility in areas where the tree is present.
Alnus jorullensis produces small and pendulous flowers, which are catkins that appear in late winter or early spring. These flowers are wind-pollinated and give rise to fruiting cones containing tiny seeds. The tree is often cultivated for ornamental purposes due to its attractive foliage and graceful appearance.
Due to its adaptability and ecological benefits, Alnus jorullensis has been introduced to various regions beyond its native range, including parts of Europe, Africa, and Asia. It is regarded as an important species for reforestation efforts in areas prone to erosion or in need of habitat restoration.

The word "Alnus jorullensis" is a scientific name for a tree species known as the Jorullo Alder. In botanical nomenclature, scientific names are given using a standardized format called binomial nomenclature, which consists of two parts: the genus name (Alnus) and the species name (jorullensis).
The genus name "Alnus" has its roots in Latin and ultimately derives from the ancient Celtic word "aln" or "alen" which referred to the alder tree. The species name "jorullensis" is derived from the Jorullo Volcano, located in the state of Michoacán, Mexico.
