Persea indica explained

Persea indica is a large, evergreen tree in the laurel family (Lauraceae), native to humid uplands on Madeira and the Canary Islands in the North Atlantic. It belongs to the genus Persea, a group of evergreen trees including the avocado. It is threatened by habitat loss.

It has been introduced to a number of islands in the nearby Azores.

Overview

Fossil evidence indicates that genus Persea originated in West Africa during the Paleocene, and spread to Asia, South America, Europe and North America. It is thought that the gradual drying of Africa, west Asia, and the Mediterranean from the Oligocene to the Pleistocene, and the glaciation of Europe during the Pleistocene, caused the extinction of the genus across these regions, resulting in the present distribution. Genus Persea disappeared from increasingly xerophytic Africa, starting with the formation of the Benguela Current. It is extinct in Africa, save for P. indica, which survives in the cloud forests of the Canary Islands.

Fossil record

Fossils of Persea indica have been described from the fossil flora of Kızılcahamam district in Turkey, which is of early Pliocene age.[1]
