TINY JOY NOV-DEC 99 (#)
„Arabica is the only species (out of 600 or so) in the genus Coffea to be autogamous, meaning that it can fertilize itself with its own pollen resulting in distinct cultivars with distinct cup qualities. Also interesting to note is that wild coffea varieties (which would make awful coffee too) have 22 chromosomes, Canephora has 22, but some time long ago Arabica was formed naturally in the Harar region of Ethiopia by the cross of 2 wild coffee species followed by a spontaneous natural duplication of its chromosomes to 44. Bless that day!“

„Amarello - This cultivar, as its name indicates, produces a yellow fruit. It is not widely planted. It matures slower than its red counterpart since darker colors absorb more sunlight. For this reason, some claim it has a higher quality. Blue mountain - A famous cultivar favored for its resistance to the coffee berry disease and ability to thrive in high altitudes. Grown in Jamaica and now in Kona, Hawaii.“

What Is Coffee? - National Coffee Association
„Coffee traces its biological heritage to a genus of plants known as Coffea. Within the genus there are over 500 genera and 6,000 species of tropical trees and shrubs. The genus was first described in the 18th century by the Swedish botanist, Carolus Linneaus, who also described Coffea arabica in his Species Plantarum in 1753. Botanists have disagreed ever since on the exact classification. This is understandable considering that coffee plants can range from small shrubs to tall trees, with leaves from 1 to 40 centimeters in size, and from purple or yellow, to the predominant dark green, in color. It has been estimated that there are anywhere from 25 to 100 species of coffee plants.“

„Coffee plants belong to the botanical genus Coffea in the family Rubiaceae, which has 500 genera and over 6,000 species. Although there is some disagreement, the number of species belonging to Coffea ranges from 25 to 100. Most commercial green coffee is either the C. arabica or C. canephora species, which is referred to commercially as Arabica and Robusta, respectively. Coffea arabica is an allotetraploid inbreeder (2n = 44). Forty to fifty cultivars (infraspecific taxa) are known, and are suspected to be derived from two cultivars of C.“

„COFFEE: A tree, its seeds, and the beverage made from them. The coffee tree, a small evergreen of the genus Coffea, has smooth, ovate leaves and the clusters of fragrant white flowers that mature into deep red fruits abut ½ inches (1.27 cm) long. The fruit usually contains two seeds, the coffee beans, C. Arabica yields the highest-quality beans and provides the bulk of the world's coffee.“
