Coffea is a genus of flowering plants in the family Rubiaceae. Coffea species are shrubs or small trees native to tropical and southern Africa and tropical Asia. The seeds of some species, called coffee beans, are used to flavor various beverages and products. The fruits, like the seeds, contain a large amount of caffeine, and have a distinct sweet taste and are often juiced. The plant ranks as one of the world's most valuable and widely traded commodity crops and is an important export product of several countries, including those in Central and South America, the Caribbean and Africa.
The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include Coffea, the source of coffee, Cinchona, the source of the antimalarial alkaloid quinine, some dye plants, and ornamental cultivars.
Syzygium samarangense is a species of flowering plant in the family Myrtaceae, native to an area that includes the Greater Sunda Islands, Malay Peninsula and the Andaman and Nicobar Islands, but introduced in prehistoric times to a wider area and now widely cultivated in the tropics. Common names in English include wax apple, Java apple, Semarang rose-apple and wax jambu.
The curry tree, Murraya koenigii or Bergera koenigii, is a tropical and sub-tropical tree in the family Rutaceae, native to Asia. The plant is also sometimes called sweet neem, though M. koenigii is in a different family to neem, Azadirachta indica, which is in the related family Meliaceae.
Coffea arabica, also known as the Arabic coffee, is a species of flowering plant in the coffee and madder family Rubiaceae. It is believed to be the first species of coffee to have been cultivated and is currently the dominant cultivar, representing about 60% of global production. Coffee produced from the less acidic, more bitter, and more highly caffeinated robusta bean makes up most of the remaining coffee production. Arabica coffee originates from and was first cultivated in Yemen, and documented by the 12th century. Coffea arabica is called بُنّ in Arabic, borrowed from the Amharic "Buna".
A coffee bean is a seed of the Coffea plant and the source for coffee. It is the pip inside the red or purple fruit often referred to as a coffee cherry. Just like ordinary cherries, the coffee fruit is also a so-called stone fruit. Even though the coffee beans are not technically beans, they are referred to as such because of their resemblance to true beans. The fruits; cherries or berries, most commonly contain two stones with their flat sides together. A small percentage of cherries contain a single seed, instead of the usual two. This is called a "peaberry". The peaberry occurs only between 10% and 15% of the time, and it is a fairly common belief that they have more flavour than normal coffee beans. Like Brazil nuts and white rice, coffee beans consist mostly of endosperm.
Coffea canephora is a species of coffee that has its origins in central and western sub-Saharan Africa. It is a species of flowering plant in the family Rubiaceae. Though widely known as Coffea robusta, the plant is scientifically identified as Coffea canephora, which has two main varieties, robusta and nganda.
Olea capensis, the black ironwood, is an African tree species in the olive family Oleaceae. It is widespread in sub-Saharan Africa: from the east in Somalia, Ethiopia and Sudan, south to the tip of South Africa, and west to Cameroon, Sierra Leone and the islands of the Gulf of Guinea, as well as Madagascar and the Comoros. It occurs in bush, littoral scrub and evergreen forest.
Alocasia sanderiana, commonly known as the kris plant or Sander's alocasia, is a plant in the family Araceae. It is endemic to Northern Mindanao in the Philippines, but is commonly grown as an ornamental plant worldwide. It is classified as critically endangered in the wild by the International Union for Conservation of Nature.
Mycosphaerella coffeicola is a sexually reproducing fungal plant pathogen. It is most commonly referred to as the asexual organism Cercospora coffeicola.
Colletotrichum kahawae is a fungal plant pathogen that causes coffee berry disease (CBD) on Coffea arabica crops. The pathogen is an ascomycete that reproduces asexually. The asexual spores (conidia) are stored within acervuli. This disease is considered to be one of the major factors hampering C.arabica production in the African continent, which represents the current geographic range of the fungus. Coffee berry disease causes dark necrosis in spots and causes the green berries of the coffee to drop prematurely. High humidity, relatively warm temperatures, and high altitude are ideal for disease formation. Given the severity of the disease and the lack of effective control measures, there is great concern that the fungus may spread to other coffee producing continents, such as South America, which could have catastrophic consequences.
Grewia asiatica, commonly known as phalsa or falsa, is a species of flowering plant in the mallow family Malvaceae. It was first found in Varanasi, India, and was taken by Buddhist scholars to other Asian countries and the rest of the world. Grewia celtidifolia was initially considered a mere variety of phalsa, but is now recognized as a distinct species.
Coffea liberica, commonly known as the Liberian coffee, is a species of flowering plant in the family Rubiaceae from which coffee is produced. It is native to western and central Africa from Liberia to Uganda and Angola, and has become naturalised in the Philippines, Indonesia, Seychelles, the Andaman & Nicobar Islands, and Malaysia.
Gesha coffee, sometimes referred to as Geisha coffee, is a variety of coffee tree that originated in the Gori Gesha forest, Ethiopia, though it is now grown in several other nations in Africa, Asia, and the Americas. It is widely known for its unique flavor profile of floral and sweet notes, its high selling price, and its exclusivity as its demand has increased over the years.
Coffee is Uganda's top-earning export crop. In 1989 Uganda's coffee production capacity exceeded its quota of 2.3 million bags, but export volumes were still diminished by economic and security problems, and large amounts of coffee beans were still being smuggled out of Uganda for sale in neighbouring countries. Uganda is one of the few countries in the world with indigenous coffee, with Robusta coffee growing wild around Lake Victoria.
Coffee production in Guam is limited to local consumption. Like cacao, coffee has been introduced to and thrives in Guam. In the early 20th century, coffee was described as one Guam's most common plants, growing about most of the dwelling houses, and nearly every family has its cultivated patch. The climate and soil of the island is well adapted to it, producing the crop from sea level to the hill tops.
Coffea racemosa, also known as racemosa coffee and Inhambane coffee, is a species of flowering plant in the family Rubiaceae. It has naturally low levels of caffeine, less than half of that found in Coffea arabica, and a quarter of that in Robusta coffee. It is endemic to the coastal forest belt between northern KwaZulu-Natal in South Africa and Zimbabwe, found in an area less than 150 km2 (58 sq mi) in size. It was widely cultivated by the Portuguese during the 1960-1970s in Mozambique, currently there are only two plantations at Ibo Island and in Hluhluwe, which remain.
Grewia flavescens, called rough-leaved raisin, sandpaper raisin, and donkey berry, is a species of flowering plant in the family Malvaceae, native to sub‑Saharan Africa, Yemen, Saudi Arabia, and India. It is considered to be an underutilized crop, both for its fruit and its use for livestock forage.
Coffea affinis is a species of plant from the family Rubiaceae. It is a largely unknown coffee bean found in West Africa.
