Amiedi is a soup eaten by the Urhobo people of Nigeria.
 It is made with palm oil ("Elaeis guineensis") extract.
Valeriana is a genus of flowering plants in the family Caprifoliaceae, members of which may by commonly known as valerians.
 It contains many species, including the garden valerian, "Valeriana officinalis".
 Some species are native to Europe, others to North America and South America (especially in the Andes).
Cadang-cadang is a disease caused by Coconut cadang-cadang viroid (CCCVd), a lethal viroid of Coconut ("Cocos nucifera"), Anahaw ("Livistona rotundifolia") Buri ("Corypha utan"), and African Oil Palm ("Elaeis guineensis").
 The name cadang-cadang comes from the word gadang-gadang that means dying in Bicol.
 It was originally reported on San Miguel Island in the Philippines in 1927/1928.
 "By 1962, all but 100 of 250,000 palms on this island had died from the disease," indicating an epidemic.
 Every year one million coconut palms are killed by CCCVd and over 30 million coconut palms have been killed since Cadang-cadang has been discovered.
 CCCVd directly affects the production of copra, a raw material for coconut oil and animal feed.
 Total losses of about 30 million palms and annual yield losses of about 22,000 tons of copra have been attributed to Cadang-cadang disease in the Philippines.
Ganoderma orbiforme is a species of polypore fungus that is widespread across southeast Asia.
 It is a plant pathogen that causes basal stem rot, a disease of the African oil palm ("Elaeis guineensis").
 The fungus was first described scientifically in 1838 by Elias Magnus Fries from collections made in Guinea.
 Leif Ryvarden transferred it to the genus "Ganoderma" in 2000.
 In addition to its type locality, the fungus has also been collected from the Bonin Islands in the Pacific, and from Venezuela and Puerto Rico.
 Microsatellite markers have been developed to help identify the fungus and study the genetic diversity of "G. orbiforme".
Palm oil (also known as dendê oil, from Portuguese ] ) is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of the oil palms, primarily the African oil palm "Elaeis guineensis", and to a lesser extent from the American oil palm "Elaeis oleifera" and the maripa palm "Attalea maripa".
Palm kernel oil is an edible plant oil derived from the kernel of the oil palm "Elaeis guineensis".
 It should not be confused with the other two edible oils derived from palm fruits: palm oil, extracted from the pulp of the oil palm fruit, and coconut oil, extracted from the kernel of the coconut.
Motandra guineensis grows as a climbing shrub or liana up to 40 m long, with a stem diameter of up to 10 cm .
 Its fragrant flowers feature a white to greenish white corolla.
 Fruit is dark green with paired follicles, each up to 18 cm long.
 "M. guineensis" is found in a variety of habitats from sea-level to 1200 m altitude.
 Local medicinal uses include as a treatment for eye infections, toothache, headache and postpartum stomach pain.
 The plant is found in Guinea, Mali, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Benin, Nigeria, Sudan, Cameroon, the Central African Republic, Gabon, the Republic of Congo, the Democratic Republic of Congo, Burundi, Uganda and Angola.
Elaeis guineensis is a species of palm commonly called African oil palm or macaw-fat.
 It is the principal source of palm oil.
 It is native to west and southwest Africa, specifically the area between Angola and the Gambia; the species name "guineensis" refers to the name for the area, Guinea, and not the modern country which now bears that name.
 The species is also now naturalised in Madagascar, Sri Lanka, Malaysia, Indonesia, Central America, the West Indies and several islands in the Indian and Pacific Oceans.
 The closely related American oil palm "Elaeis oleifera" and a more distantly related palm, "Attalea maripa", are also used to produce palm oil.
Valeriana occidentalis is a species of flowering plant in the honeysuckle family known by the common name western valerian.
 It is native to the western United States, particularly the northwestern quadrant, but it occurs as far south as Arizona and as far east as Colorado and South Dakota.
 It occurs in moist, forested mountain habitat.
 It is an erect herb growing 30 to 75 centimeters tall with whorls or opposite pairs of leaves at intervals along stem.
 The leaves are generally divided into lobes or are compound, with each leaf made up of a few oval-shaped leaflets.
 The inflorescence is a dense cyme of many funnel-shaped white flowers each 3 or 4 millimeters long with three long, protruding stamens.
 The fruit is a ribbed achene about half a centimeter long which may be tipped with the featherlike remains of the flower sepals.
Palm butter or palm cream, frequently known as moambe, mwambe or nyembwe, is an ingredient made from the pericarp (not the seeds) of palm nuts, the fruit of the African oil palm ("Elaeis guineensis") tree.
 It forms an important ingredient in stews and sauces in African cuisine.
