Description

FRUIT. Elliptical or globose, asymmetrical at the apex, length 10–23 mm, width 8–11 mm, thickness 6–13 mm.

ENDOCARP. Elliptical in lateral view, length ca 12 mm, width ca 8.8 mm, thickness ca 6.9 mm. Keel surrounding the endocarp in the plane of symmetry. Apex slightly asymmetrical and acute; base with small rounded protuberance at the point of the base. Outer surface of the endocarp rugose, irregular; rugosities distributed randomly at the surface. Vasculature of the endocarp free. Endocarp wall 373– 468 µm thick excluding rugosities (535–545 µm thick including rugosities). Endocarp wall with two cell layers: outermost layer with 10–12 rows of anticlinally oriented cells, cells 15.7–34.0 µm in length; innermost layer with 10 rows of periclinally oriented cells, cells 13.8–19.8 µm in width. Locule surface smooth, not lacunate.
