Blighia is a genus of three species of flowering plants in the soapberry family, Sapindaceae. They are trees or large shrubs native to tropical Africa from Guinea east to Kenya, and south to Angola and KwaZulu-Natal. [1] The fruit is partly edible, with the Ackee (B. sapida) being grown commercially for fruit production. The genus is named for Captain William Bligh (formerly of HMS Bounty), who brought samples back to England.

The species are evergreen trees growing to 10–20 metres (33–66 ft) tall, with pinnate leaves. The flowers are produced in small panicles. The fruit is an oval capsule 4–8 centimetres (2–3 in) long containing three seeds, each surrounded by an edible fleshy yellow aril, and a thick, leathery orange or red skin; the fruit apart from the aril is very poisonous.

<span class="mw-page-title-main">Aril</span> Membranous or fleshy appendage that partly or wholly covers a seed

An aril, also called an arillus, is a specialized outgrowth from a seed that partly or completely covers the seed. An arillode or false aril is sometimes distinguished: whereas an aril grows from the attachment point of the seed to the ovary, an arillode forms from a different point on the seed coat. The term "aril" is sometimes applied to any fleshy appendage of the seed in flowering plants, such as the mace of the nutmeg seed. Arils and arillodes are often edible enticements that encourage animals to transport the seed, thereby assisting in seed dispersal. Pseudarils are aril-like structures commonly found on the pyrenes of Burseraceae species that develop from the mesocarp of the ovary. The fleshy, edible pericarp splits neatly in two halves, then falling away or being eaten to reveal a brightly coloured pseudaril around the black seed.

<i>Artocarpus integer</i> Asian tree related to breadfruit and jackfruit

Artocarpus integer, commonly known as chempedak or cempedak, is a species of tree in the family Moraceae, in the same genus as breadfruit and jackfruit. It is native to Southeast Asia. Cempedak is an important crop in Malaysia and is also popularly cultivated in southern Thailand and parts of Indonesia, and has the potential to be utilized in other areas. It is currently limited in range to Southeast Asia, with some trees in Australia and Hawaii.

<i>Coccinia</i> Genus of flowering plants

The scarlet gourds are a genus with 25 species. It is distributed in sub-Saharan Africa and with one species, C. grandis also in South Asia and Southeast Asia, and it is also introduced into the New World. Incidentally, C. grandis is also a cultivated crop and it is used for culinary and medical purposes.

<i>Lansium parasiticum</i> Species of tree

Lansium parasiticum, commonly known as langsat, is a species of tree in the family Meliaceae with commercially cultivated edible fruits. The species is native to Southeast Asia. Despite its name, it is not parasitic; the specific epithet parasiticum derives from the fact that it can grow as an epiphyte in the wild, which was once thought to be an indication of parasitism.

<i>Artocarpus odoratissimus</i> Species of plant in the family Moraceae

Artocarpus odoratissimus is a species of flowering plant in the Moraceae family. It is a commonly called marang, madang, timadang, terap, tarap, kiran, green pedalai, or johey oak. It is native to Borneo, Palawan, and Mindanao Island, and is closely related to the jackfruit, cempedak, and breadfruit trees which all belong to the same genus, Artocarpus.

<span class="mw-page-title-main">Red-flanked duiker</span> Species of mammal

The red-flanked duiker is a species of small antelope found in western and central Africa in countries as far apart as Senegal and Sudan. Red-flanked duikers grow to almost 15 in (35 cm) in height and weigh up to 31 lb (14 kg). They have russet coats, with greyish-black legs and backs, and white underbellies. They feed on leaves, fallen fruits, seeds and flowers, and sometimes twigs and shoots. The adults are territorial, living in savannah and lightly wooded habitats, and the females usually produce a single offspring each year. They have lifespans of ten to fifteen years in captivity.

Jamaican vomiting sickness, also known as toxic hypoglycemic syndrome (THS), acute ackee fruit intoxication, or ackee poisoning, is an acute illness caused by the toxins hypoglycin A and hypoglycin B, which are present in fruit of the ackee tree. While in the fully ripened arils, hypoglycin A is at levels of less than 0.1 ppm, in unripe arils it can be over 1000 ppm and can cause vomiting and even death. Some countries in the Caribbean and Western Africa experience frequent cases.

<span class="mw-page-title-main">Hypoglycin A</span> Chemical compound

Hypoglycin A is a naturally occurring amino acid derivative found in the unripened fruit of the Ackee tree and in the seeds of the box elder tree. It is toxic if ingested, and is the causative agent of Jamaican vomiting sickness. A 2017 Lancet report established a link between the consumption of unripened lychees resulting in hypoglycaemia and death from acute toxic encephalopathy.

<span class="mw-page-title-main">Hypoglycin B</span> Chemical compound

Hypoglycin B is a naturally occurring organic compound in the species Blighia sapida. It is particularly concentrated in the fruit of the plant especially in the seeds. Hypoglycin B is toxic if ingested and is one of the causative agents of Jamaican vomiting sickness. It is a dipeptide of glutamic acid and hypoglycin A.

<i>Inga edulis</i> Species of tree

Inga edulis, known as ice-cream bean, ice-cream-bean, joaquiniquil, cuaniquilguama or guaba, is a fruit native to South America. It is in the mimosoid tribe of the legume family Fabaceae. It is widely grown, especially by Indigenous Amazonians, for shade, food, timber, medicine, and production of the alcoholic beverage cachiri. It is popular in Peru, Ecuador, Pernambuco-Brazil, Venezuela and Colombia. The taxonomic name Inga is derived from its name with the Tupí people of South America (ingá) while the species name edulis is Latin for "edible". The common name "ice-cream bean" alludes to the sweet flavor and smooth texture of the pulp.

Nina Lilian Etkin was an anthropologist and biologist. Etkin was noted for her work in medical anthropology, ethnobiology, and ethnopharmacology.

Her work involved complementary and alternative medicines for prevention and treatment in Hawai‘i; the use of ethnomedicines in Indonesia; and health issues in Nigeria. She won numerous grants and awards from national and international agencies and published several books as well as over 80 professional articles in peer reviewed journals.

<span class="mw-page-title-main">Methylene cyclopropyl acetic acid</span> Chemical compound

Methylene cyclopropyl acetic acid (MCPA) is found in lychee seeds and also a toxic metabolite in mammalian digestion after eating hypoglycin, present in the unripe ackee fruit, grown in Jamaica and in Africa. By blocking coenzyme A and carnitine, MPCA causes a decrease in β-oxidation of fatty acids, and hence gluconeogenesis.

<i>Diploglottis diphyllostegia</i> Species of plant in the family Sapindaceae

Diploglottis diphyllostegia, commonly known as the northern tamarind, native tamarind or wild tamarind, is a tree in the lychee family Sapindaceae which is endemic to Queensland, Australia. It is an attractive tree with potential in cultivation, with a dense crown of dark green leaves and masses of fruit in spring and summer.
