The coffee plant is a woody perennial evergreen dicotyledon that belongs to the Rubiaceae family. It has a main vertical trunk (orthotropic) and primary, secondary, and tertiary horizontal branches (plagiotropic). Two main species of coffee are cultivated today. Coffea arabica known as Arabica coffee accounts for 75-80% of the world's production. Coffea canephora, known as Robusta coffee, is more robust than the Arabica plants, but produces an inferior tasting beverage with a higher caffeine content. The coffee plant can grow to heights of 10 meters if not pruned, but producing countries will maintain the coffee at a height reasonable for easy harvesting.
Arabica contains less caffeine than any other commercially cultivated species of coffee. Wild plants grow to between 7-12 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 produced in axillary clusters, each flower white, and 1-1.5 cm diameter. The fruit is a berry 10-15 mm long, maturing bright red to purple, containing two seeds (the coffee 'bean').Also used as a traditional medicine. Reported to be analgesic, anaphrodisiac, anorexic, antidotal, cardiotonic, CNS-stimulant, counterirritant, diuretic, hypnotic, lactagogue, nervine, stimulant, coffee is a folk remedy for asthma, atropine-poisoning, fever, flu, headache, jaundice, malaria, migraine, narcosis, nephrosis, opium-poisoning, sores, and vertigo.
