"Coffee is the seed of an evergreen shrub, which is cultivated in hot climates, and is a native of Abyssinia and of Arabia. This shrub is from 15 to 20 feet in height, and belongs to the Rubiaceæ. The fruit is of an oval shape, about the size of a cherry, and of a dark-red color when ripe. Each of these contains two cells, and each cell a single seed, which is the coffee as we see it before it undergoes the process of roasting."—(Charles Leonard-Stuart, 1911)

"The bean with its roots in unboiled water will grow for a considerable time, as long as the mineral matter in the water will provide it with food materials. The roots of the plant in the boiled water will quickly die and the whole plant will then wither, because the roots no longer send the water up to the leaves." — Ritchie, 1918

A trailing plant of the bean family, bearing a hairy stem, small yellow flowers, and two-paired primate leaflets. The flowers are sterile above ground. After they wither, the forming stalk of the ovary bends downward and forces the young pod underground, and the seeds mature some distance below the surface.

The pea weevils or seed beetles are a subfamily (Bruchinae) of beetles, now placed in the family Chrysomelidae, though they have historically been treated as a separate family. They are granivores, and typically infest various kinds of seeds or beans, living for most of their lives inside a single seed. The family includes about 1,350 species found worldwide.

Coca is a plant in the family Erythroxylaceae, native to north-western South America. The plant plays a significant role in traditional Andean culture. Coca leaves contain cocaine alkaloids, a basis for the drug cocaine, which is a powerful stimulant. Coca should not be confused with the similarly named South American cocoa bean from which chocolate is made. The plant resembles a blackthorn bush, and grows to a height of 2&ndash;3 m (7&ndash;10 ft). The branches are straight, and the leaves, which have a green tint, are thin, opaque, oval, and taper at the extremities. A marked characteristic of the leaf is an areolated portion bounded by two longitudinal curved lines, one line on each side of the midrib, and more conspicuous on the under face of the leaf. The flowers are small, and disposed in little clusters on short stalks; the corolla is composed of five yellowish-white petals, the anthers are heart-shaped, and the pistil consists of three carpels united to form a three-chambered ovary. The flowers mature into red berries.

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').
