FRUIT. Elliptical; epicarp puberulent with yellow simple hairs with granular ornamentation, shriveled when dry, revealing the underlying reticulum of endocarp ridges. Mesocarp 135–150 µm thick when dry. Length 10.0– 12.4 mm, width 7.0– 9.6 mm, thickness 6.0– 8.9 mm.

ENDOCARP. Cream, elliptical in lateral view, globose in transverse section, length ca 10.9 mm, width ca 9.9 mm, thickness ca 7.5 mm. Keel surrounding the endocarp in the plane of symmetry, with the thicker margin containing the primary vascular bundle embedded within the endocarp wall, occasionally divided into two parts subapically. Apex asymmetrical in lateral view; base rounded-flat and symmetrical. Outer surface of the endocarp ridged, with three main longitudinal ridges; the median ridge beginning at the point of the base then dichotomizing at the ¾ of the endocarp length; the apical ¼ of the endocarp length is ridgeless. Ridges rounded and thin, each with a median channel, enclosing 1–3 polygonal areoles, extended transversally and longitudinally. Vasculature of the endocarp resting in the channels of the ridges. Endocarp wall 154–181 µm thick excluding ridges (460–470 µm thick including ridges). Endocarp wall homogenous, with 9–12 rows of isodiametric cells, 14–26 µm in diameter. Locule surface unknown, lacunate.


A tissue (placenta?, degradation?) obscures the surface of the locule.
