a small tuft of hair; a cavity or pocket formed by a plant which is usually inhabited by insects, particularly ants or mites. Domatia are usually found in the axils of the lateral veins where they meet the main vein on the underside of the leaf and there is often a corresponding raised dome on the upper surface of the leaf.
