Coffee plants in Zambia. [photos by S van Noort, Iziko ]

A shrub or small tree with clusters of two-seeded fruit (the seeds being the 'coffee beans') that are red or purple when ripe. Native to Ethiopia but the commercialisation of coffee as a drink has its origins in Arabia (Yemen), which had a monopoly over the market from about 1400 to 1700 AD. Coffee is now produced worldwide in tropical regions but most of the production is from Brazil and Colombia. Coffee is drunk mainly because of the stimulating effects of caffeine - a typical cup of coffee has about 150 mg of this addictive substance. However, many people simply like its taste and smell, hence the popularity of decaffeinated coffee.

See also Cichorium intybus (Chicory), which is used as a coffee substitute or addititive.

Ecological relationships

Bacteria

Acid-producing, nitrogen-fixing bacteria that are found in roots, rhizospheres and stems of coffee plants.
