Picconia is a genus of two species of flowering plants in the family Oleaceae, found in the laurel forests habitat of Macaronesia. [1]
They are evergreen shrubs to trees with large, opposite, entire, shiny, ovoid leaves and numerous flowers. The fruit is a drupe. The flowers are small, white and fragrant, followed by one-seeded, olive-like green fruits, ripening to bluish-black. [2] Picconia are native of open spots in the laurel forest of the Azores, Madeira and Canary Islands where they are found only in the humid to hyper-humid evergreen forests of the cloud belt. [3] Tree species with laurel-like leaves are predominant, forming a dense canopy up to 40 m high that blocks out most light, resulting in scant vegetation in the understory. [3] Most of these tree species in Africa are ancient paleoendemic [4] species of the genera Laurus, Ocotea, Persea, and Picconia, which in ancient times were widely distributed on the African and European continents.

Macaronesia is a collection of four volcanic archipelagos in the North Atlantic Ocean, off the coasts of the continents of Africa and Europe. Each archipelago is made up of a number of Atlantic oceanic islands, which are formed by seamounts on the ocean floor that have peaks above the ocean's surface. Some of the Macaronesian islands belong to Portugal, some belong to Spain, and the rest belong to Cape Verde. Politically, the islands belonging to Portugal and Spain are part of the European Union. Geologically, Macaronesia is part of the African tectonic plate. Some of its islands – the Azores – are situated along the edge of that plate at the point where it abuts the Eurasian and North American plates.
The trocaz pigeon, Madeira laurel pigeon or long-toed pigeon is a pigeon which is endemic to the island of Madeira. It is a mainly grey bird with a pinkish breast; its silvery neck patch and lack of white wing markings distinguish it from its close relative and probable ancestor, the common wood pigeon. Its call is a characteristic six-note cooing, weaker and lower-pitched than that of the wood pigeon. Despite its bulky, long-tailed appearance, this pigeon has a fast, direct flight.
Bolle's pigeon is a species of the genus Columba of family Columbidae, doves and pigeons, endemic to the Canary Islands, Spain. This bird is named after the German naturalist Carl Bolle, who was the first to distinguish it from the laurel pigeon. This wood pigeon is endemic to the laurel forest habitat.
The laurel pigeon or white-tailed laurel pigeon is a species of bird in the Columba genus in the family Columbidae. It is endemic to the Canary Islands, Spain, and resides in laurel forest habitat. It is the animal symbol of the island of La Gomera.
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.
Laurus is a genus of evergreen trees or shrubs belonging to the laurel family, Lauraceae. The genus contains three or more species, including the bay laurel or sweet bay, L. nobilis, widely cultivated as an ornamental plant and a culinary herb.
Garajonay National Park is located in the center and north of the island of La Gomera, one of the Canary Islands (Spain). It was declared a national park in 1981 and a World Heritage Site by UNESCO in 1986. It occupies 40 km2 and it extends into each of the six municipalities on the island.
Prunus lusitanica, the Portuguese laurel cherry or Portugal laurel, is a species of flowering plant in the rose family Rosaceae, native to southwestern France, Spain, Portugal, Morocco, and Macaronesia.
Laurus azorica, the Azores laurel or Macaronesian laurel is a species of plant in the laurel family (Lauraceae). It is endemic to the Azores.
Ocotea foetens, commonly called til or stinkwood is a species of tree in the family Lauraceae. It is evergreen and grows up to 40 m tall. It is a common constituent of the laurisilva forests of Madeira and the Canary Islands. Leaf fossils of this species are known from the Mio-Pleistocene of Madeira Island.
Picconia azorica, locally known as pau-branco, is a species of Picconia common to the majority of islands of the Portuguese archipelago of the Azores, where it is endemic. It can grow to a medium-sized tree, though it is usually found in the form of a shrub. It is threatened by habitat loss.
Picconia excelsa is a species of Picconia, endemic to Macaronesia, occurring on the Canary Islands (Spain) and Madeira (Portugal).
The Azores wood pigeon, Columba palumbus azorica is an endemic subspecies of the common wood pigeon, located in the Atlantic Azores islands of Portugal. This endemic subspecies is the only live pigeon present in the laurel forest habitat of the Azores Islands.
Laurus novocanariensis is a large shrub or tree with aromatic, shiny dark-green foliage. belonging to the evergreen tree genus Laurus of the laurel family, Lauraceae. The genus includes three species, whose diagnostic key characters often overlap. Under favorable conditions it is an impressive tree of 3 to 20 m. tall. It is native of rich soils in the cloud zone of always moist spots in subtropical climate with a high air-humidity, on the Canary and Madeira islands.
Hedera canariensis, the Canary Island ivy, Canary ivy or Madeira ivy, is a species of ivy, native to the Canary Islands and possibly the Atlantic coast of northern Africa.
Hedera azorica, the Azores ivy, is a species of ivy which is native to the Atlantic coast in the Azores Islands. It is an evergreen climbing plant, growing to 20–30 m high where suitable surfaces are available, and grows as ground cover where there are no vertical surfaces. It climbs by means of aerial rootlets which cling to the substrate.
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 laurissilva, once covered the islands. Over centuries the forests were mostly cleared. Madeira's remaining forests are now protected.
The Azores temperate mixed forests is a temperate broadleaf and mixed forests ecoregion of southwestern Europe. It encompasses the Azores archipelago in the Atlantic Ocean. These volcanic islands are an autonomous region of Portugal, and lie 1500 km west of the Portuguese mainland.
Ilex perado, the Macaronesian holly, is a species of holly endemic to Macaronesia, distributed throughout the Azores, Madeira and Canary islands. It is an important component of the natural high-altitude Macaronesian rainforest, known as 'laurisilva', found mostly at 500 to 1,200 m altitude but it also appears in forest formations at lower altitudes. Many of the subspecies have been classified as threatened, probably because of very small population sizes, and are protected by local, national and regional legislation.
