Abstract
THE anormalis factor (Am Am) of Coffea arabica affects the size of the plant, its branching habit and its leaves, flowers, fruits and seeds. The internodes of the branches are shorter than in the typica variety, taken as standard. The leaves are extremely abnormal, often almost palmate and of various sizes. The corolla has a variable number of lobes, the stamens are almost normal, but the style and stigma are very reduced and misshaped. The number of flowers and fruits is normal. The seeds have a slightly corrugated surface. A rather high percentage of loeules contains more than one ovule. The anormalis shows incomplete dominance in F 1.
