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. [1] 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. [1]

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.
Fossils of Persea indica have been described from the fossil flora of Kızılcahamam district in Turkey, which is of early Pliocene age. [2]
Lauraceae, or the laurels, is a plant family that includes the true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genera worldwide. They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as Sassafras, are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. The genus Cassytha is unique in the Lauraceae in that its members are parasitic vines. Most laurels are highly poisonous.

Tilia platyphyllos, the large-leaved lime or large-leaved linden, is a species of flowering plant in the family Malvaceae (Tiliaceae). It is a deciduous tree, native to much of continental Europe as well as southwestern Great Britain, growing on lime-rich soils. The common names largeleaf linden and large-leaved linden are in standard use throughout the English-speaking world except in the British Isles, where it is known as large-leaved lime. The name "lime", possibly a corruption of "line" originally from "lind", has been in use for centuries and also attaches to other species of Tilia. It is not, however, closely related to the lime fruit tree, a species of citrus.
Pinus canariensis, the Canary Island pine, is a species of gymnosperm in the conifer family Pinaceae. It is a large, evergreen tree, native and endemic to the outer Canary Islands of the Atlantic Ocean.

Persea is a genus of about 150 species of evergreen trees belonging to the laurel family, Lauraceae. The best-known member of the genus is the avocado, P. americana, widely cultivated in subtropical regions for its large, edible fruit.
Laurel forest, also called laurisilva or laurissilva, is a type of subtropical forest found in areas with high humidity and relatively stable, mild temperatures. The forest is characterized by broadleaf tree species with evergreen, glossy and elongated leaves, known as "laurophyll" or "lauroid". Plants from the laurel family (Lauraceae) may or may not be present, depending on the location.

This fossil flora in Turkey stems from at least six Pliocene deposits in Güvem and Beşkonak villages, 80 kilometres (50 mi) north of Ankara, 22 kilometres (14 mi) north of Kızılcahamam and 125 kilometres (78 mi) south of the Black Sea coast. They are 1,000 metres (3,300 ft) to 1,500 metres (4,900 ft) above sea level, extending 15 kilometres (9.3 mi) north-south and 7 kilometres (4.3 mi) east-west. Between six and seven million years ago, a fresh water lake existed there in a forested area with mostly broad leaved deciduous tree species, dominated by sequoia and oak.
The Madeira evergreen forests is a laurissilva ecoregion of southwestern Europe. It covers the archipelago of Madeira and some nearby islands in the Atlantic Ocean. Laurel forest, known as Laurisilva of Madeira, once covered the islands. Over centuries the laurel forests were mostly cleared. Madeira's remaining forests are now protected.
