The 2 basic species of the coffeetree or coffea produce 2 different species which support the world coffee market: Coffea Robusta and the coffea Arabica
- Coffea arabica (pronounced /əˈræbɪkə/) is a species of coffee indigenous to Ethiopia and Yemen. It is also known as the "coffee shrub of Arabia", "mountain coffee" or "arabica coffee". Coffea arabica is believed to be the first species of coffee to be cultivated, being grown in southwest Arabia for well over 1,000 years. It is considered to produce better coffee than the other major commercially grown coffee species, Coffea canephora (robusta). Arabica contains less caffeine than any other commercially cultivated species of coffee. Wild plants grow to between 9 and 12 m tall, and have an open branching system; the leaves are opposite, simple elliptic-ovate to oblong, 6-12 cm long and 4-8 cm broad, glossy dark green. The flowers are white, 10-15 mm in diameter and grow in axillary clusters. The fruit is a drupe (though commonly called a "berry") 10-15 mm in diameter, maturing bright red to purple and typically contain two seeds (the coffee 'bean').
Coffea canephora (Robusta Coffee; syn. Coffea robusta) is a species of coffee which has its origins in western Africa. It is grown mostly in Africa and Brazil, where it is often called Conillon. It is also grown in Southeast Asia where French colonists introduced it in the late 19th century. In recent years Vietnam, which only produces robusta, has surpassed Brazil, India, and Indonesia to become the world's single largest exporter. Approximately one third of the coffee produced in the world is robusta.
