Description FRUIT. Elliptical, apex slightly acuminate and asymmetrical, length 14–26 mm , width 10–20 mm , thickness 10–13 mm . ENDOCARP. Elliptical-globose in lateral view, length ca 16.4 mm , width ca 11.3 mm , thickness ca 9.3 mm . Channel surrounding the endocarp in the plane of symmetry. Apex slightly asymmetrical and acute. Outer surface of the endocarp rugose, with ca 2–3 main longitudinal channels that separate irregular mounds. Vasculature of the endocarp resting in the channels, between rugosities. Endocarp wall 692–795 µm thick with and without rugosities. Endocarp wall with two cell layers: outermost layer with 13 rows of anticlinally oriented cells, cells 16.8–30.2 µm in length, innermost layer with 20 rows of periclinally oriented cells, cells 13.5–28.2 µm in width. Inner endocarp surface smooth, lacunate.
