T.S. of the pseudoberry shows the outer tissues of thalamus separated by a zone of viscid mass from the inner tissues of the seed. Fruit tissue consist of an outer epicarp formed of a single layer of epidermis composed of squarish or rounded, thickly cuticularized cells followed by 3 or 4 layers of thick walled, larged sized, squarish cells containing tannins; mesocarp consist of multiple layers of small relatively clear cells with interspersed groups of stone cells. Fruit wall delimited inside by multiple layers of large, rounded, thin walled parenchymatous cells containing yellow to dark brown tannins; the seed consists of an outer viscid zone delimited towards inside by a ring of tissues made of several layers of isodiametric cells mostly containing brown pigment in outer 2 or 3 layers and a ring of vascular bundles. Inner to this is a zone comprising of radially elongated, compactly arranged thin-walled cells rich in starch towords the center; centre of the seed occupied by a mass of uniform, isodiametric, parenchymatous embryonic cells.
