Mesocarp ca 75 µm thick when dry. Length 10–19 mm , width 5–10 mm , thickness 4.0– 5.1 mm . ENDOCARP. Cream, length ca 13.1 mm , width ca 6.9 mm , thickness ca 4.5 mm . Outer surface of the endocarp ridged, with ca three main longitudinal ridges (with other small longitudinal ridges); the median ridge reaching the point of the base. Ridges rounded-angular and thin, delimiting a reticulate pattern, enclosing ca 20–60 small areoles with arbuscular freely ending ridgelets. Endocarp wall 135–156 µm thick excluding ridges ( 180–232 µm thick including ridges). Endocarp primary vascular bundle in a channel on the keel. Endocarp wall with three cell layers: outermost layer with 1–2 rows of isodiametric to periclinally oriented cells, cells 12.3–24.1 µm in width, followed by a layer with 8–12 rows of periclinally oriented cells, cells 9–23 µm in width. Innermost row with small periclinally oriented cells, cells ca 9 µm in width and inflated into the locule surface.
