Description

FRUIT. Elliptical, apex acute, smooth when dry. Mesocarp 200–400 µm thick when dry. Length 13– 23 mm, width 5–7 mm, thickness 8.0– 9.4 mm.

ENDOCARP. Brown, compressed in the dorsoventral axis, elliptical in lateral view, lenticular in transverse section, length ca 12.9 mm, width ca 6.5 mm, thickness ca 8.8 mm. Apex acute. Outer surface of the endocarp ridged, with ca three main longitudinal ridges; the median ridge is thicker than other ridges, spanning from the base to the apex. Ridges thin and rounded, forming a diffuse pattern of small interconnected ridges running from the main ridge. Endocarp wall 544–761 µm thick excluding ridges (744–940 µm thick including ridges). Vasculature on the endocarp surface resting on ridges, with the endocarp primary vascular bundle positioned outside the endocarp wall. Endocarp wall with ca 20 rows of isodiametric cells, homogeneous; outermost layer with 13–17 rows of cells, cells 45–60 µm in diameter; innermost layer with 5–7 rows of cells, cells 20–35 µm in diameter. Locule surface smooth and lacunate.
