oleas

Oleas is a genus of flowering plants in the family Oleaceae. The genus is native to the Mediterranean region and parts of Asia. Plants in the genus Oleas are typically shrubs or small trees, known for their leathery leaves and fragrant flowers. The most well-known species is Oleas europaea, commonly known as the olive tree. This species is cultivated for its fruit, which is used to produce olive oil and as a table olive. The olive tree has a long history of cultivation, dating back thousands of years, and is deeply embedded in the culture and mythology of many Mediterranean civilizations.

The genus Oleas is characterized by opposite, simple leaves, often entire or serrated, and small, white or creamy flowers borne in axillary clusters. The fruit is a drupe, varying in size, shape, and color depending on the species and cultivar. While Oleas europaea is by far the most economically significant species, other members of the genus are found in various habitats, from arid scrublands to montane forests. The genus is an important part of Mediterranean ecosystems and has contributed significantly to human agriculture and diet. Research continues into the genetic diversity and cultivation of Oleas species.
