The Vinhatico, or Persea indica, is
a species of plant in the Lauraceae family.
It belongs to the evergreen tree genus Persea of
about 150 species, of which the avocado, P. americana, is the best known.
It is found in
the Azores, Madeira,
and Canary Islands in Macaronesia.
It is threatened by habitat loss.
It is the vegetable symbol of the island of La Gomera.
The
Family Lauraceae was part of Gondwanaland flora.
There they spread over most of the continent. The genus Persea died
out in increasingly xerophytic Africa, starting with the freezing of Antarctica
about 20 million years ago and the formation of the Benguela current. The genus
is extinct in Africa, save for P. indica, which survives in the
fog shrouded mountains of the Canary Islands, which with Madagascar, constitute
Africa's Laurel forest plant refugia.
Fossil
evidence indicates that the genus originated in West Africa during
the Paleocene, and spread to Asia, to South America, and to Europe
and thence to 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.
P.
indica is a species exclusive to Laurisilva,
since this habitat is constantly threatened by encroaching agriculture, the
laurel forest animal or vegetal species had already become rare in many of its
former habitats and are threatened by habitat loss.
