Prunus lusitanica, the Portuguese laurel cherry [4] or Portugal laurel, [5] is a species of flowering plant in the rose family Rosaceae, native to the Iberian Peninsula, Morocco, the Macaronesian archipelagos, and the French Basque Country. [6] [7] [8]
The split between the subspecies (subsp. azorica, hixa, and lusitanica) is dated around the Pliocene. [9]
Prunus lusitanica is an evergreen shrub or small tree growing to 3-8m tall (though it can reach 15-20m in cultivation). [10] [11] [12] [13] The bark is smooth and dark-grey. [10] The leaves are alternate, oval, 7–15 cm long and 3–5 cm broad, [10] with an acute apex and a dentate margin, glossy dark green above, lighter below. [12] They superficially resemble those of the bay laurel, which accounts for its often being mistaken for one.
The flowers are small (10–15 mm diameter) with five small white petals; they are produced on erect or spreading racemes 15–25 cm long in late spring. The fruit is a small cherry-like drupe 8–13 mm in diameter, green or reddish green at first, turning dark purple or black when ripe in late summer or early autumn. [10] [14]
It occurs in the western Mediterranean Basin, France, Spain, and Portugal, and Macaronesia, Azores, Canary Islands and Madeira.
Prunus lusitanica is rare in the wild, found mainly along mountain streams, preferring sunshine and moist but well-drained soils. It is moderately drought-tolerant. It reproduces either sexually (the most successful method) or asexually by cloning from shoots. [15]
The species was first scientifically described by Linnaeus in Species Plantarum in 1753. Its specific epithet lusitanica means "of Lusitania", referring to the Roman name for Portugal. [16]
Three subspecies are accepted: [3]
Prunus lusitanica is grown as an ornamental shrub and is widely planted as a hedge and for screening in gardens and parks. It is introduced and locally naturalised in the temperate zone in northern France, Great Britain, Ireland, New Zealand, Western Canada- including the southern BC Mainland and Vancouver Island From Victoria Up Island through the Cowichan, Nanaimo and Parksville as well as the western United States in California, Oregon and Washington State.[ citation needed ]
Similar to its relative Prunus laurocerasus , P. lusitanica has been recognized by some botanists and land managers in both western Washington and Oregon as invasive. It is thought to have spread from cultivated areas into natural areas by birds who consume the fruit and then defecate the seeds away from the source plant.[ citation needed ]
It has gained the Royal Horticultural Society's Award of Garden Merit. [18]
The leaves of Prunus lusitanica contain cyanide and will release this into the environment if burnt [19] or if crushed. [20] The fruit is somewhat edible if fully ripe, but if it is bitter, it is toxic and should not be eaten. [21]
Macaronesia is a collection of four volcanic archipelagos in the North Atlantic Ocean, off the coast of North Africa and Europe. Each archipelago is made up of a number of Atlantic oceanic islands, which are formed by seamounts on the ocean floor whose peaks have risen above the ocean's surface.
Prunus laurocerasus, also known as cherry laurel, common laurel and sometimes English laurel in North America, is an evergreen species of cherry (Prunus), native to regions bordering the Black Sea in southwestern Asia and southeastern Europe, from Albania and Bulgaria east through Turkey to the Caucasus Mountains and northern Iran.
Dracaena draco, the Canary Islands dragon tree or drago, is a subtropical tree in the genus Dracaena, native to the Canary Islands, Cape Verde, Madeira, western Morocco, and possibly introduced into the Azores.
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.
Juniperus oxycedrus, vernacularly called Cade, cade juniper, prickly juniper, prickly cedar, or sharp cedar, is a species of juniper, native across the Mediterranean region, growing on a variety of rocky sites from sea level. The specific epithet oxycedrus means "sharp cedar" and this species may have been the original cedar or cedrus of the ancient Greeks.
The Habitats Directive is a directive adopted by the European Community in 1992 as a response to the Berne Convention. The European Community was reformed as the European Union the following year, but the directive is still recognised.
Cortegada is an almost tidal island in a coastal inlet near Pontevedra in Galicia, Spain. It is part of the Atlantic Islands of Galicia National Park.
Juniperus deltoides, the Eastern prickly juniper, is a species of juniper native to the eastern Mediterranean. Although it is sometimes considered a subspecies of Juniperus oxycedrus, phylogenetic studies have found the two are not closely related.
Juniperus navicularis, the Portuguese prickly juniper, is a species of juniper endemic to the southwestern Iberian Peninsula. Although it is sometimes considered a subspecies of the Mediterranean Juniperus oxycedrus, phylogenetic studies have found the two are not closely related.
Pico da Vara is the highest mountain on the island of São Miguel, in the Portuguese archipelago of the Azores, and principal special protection of the Nature Reserve of Pico da Vara. The area around the mountain includes the largest remaining stand of the native laurisilva forest on the island, home to the critically endangered endemic Azores bullfinch.
The Botanical Garden of Faial is an ecological garden, component of the Faial Nature Park, established in 1986 to educate and protect the biodiversity common on Faial, an island of the Azores archipelago.
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.
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.
Goniolimon, sometimes called the statices, are a genus of flowering plants in the leadwort and plumbago family Plumbaginaceae, native to northern Africa, southern Europe, western and central Asia, Siberia, Mongolia and China. Low-lying perennial shrubs, some species are cultivated as ground covers.
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 elevation. 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.
Herniaria lusitanica is a species of flowering plant in the family Caryophyllales. It is endemic to the Iberian Peninsula and the Berlengas archipelago.
Limonium bonduellei, the yellow statice, is a species of flowering plant in the family Plumbaginaceae. The Global Biodiversity Information Facility calls it Algerian statice and lists it as Limonium sinuatum subsp. bonduellei, but a 2018 molecular study showed that it is good species with 100% bootstrap support. An annual facultative halophyte reaching 50 cm (20 in), it is native to Spain and North Africa, and has been introduced to Italy. It is naturalized in New Zealand.
Sideritis pusilla is a species of flowering plant belonging to the family Lamiaceae.
