Coffea arabica 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').

This illustration shows a lentil plant. Lentils are the round, flat seeds of a small leguminous plant <i>(Vicia (Lens) hirsuta)</i>, of which numerous varieties are cultivated in the countries bordering the Mediterranean and elsewhere. The seeds are highly nitrogenous, and of great food value. They form the principal constituent of the well-known <i>Revalenta arabica</i> of commerce. They consist of -- starch, 50 percent; casein, 24 percent; fat, 2 percent; and water, 14 percent. The dark green German lentils are much more palatable than the reddish-yellow Egyptian variety.
