Notes on wild coffea arabica from southwestern ethiopia, with some historical considerations

That the Arabica coffee plant (C.arabica) is abundant as a spontaneous component of the rain-forest between 3000 and 6000 ft. alt. in parts of Kaffa and Illubabor provinces in southwestern Ethiopia.
That modern man’s role in the domestication ofC. arabica in rain-forest districts of Ethiopia may date from relatively recent times. In no way can coffee be considered a refined crop in these districts, as are some food plants of the area, such as sorghum, maize, Ethiopian mustard, and the pulse plants.
That genetic variability in coffee plants in rain-forest districts of Ethiopia probably is much greater than in coffee plants grown in Latin America and in other areas of the world whereC. arabica is cultivated. Yemen was the major germ plasm center of cultivated Arabica coffee until a decade or two ago. But the coffee plant is not a native of Yemen.
