FRUIT. Elliptical, asymmetrical at the apex, red-green when mature. Epicarp strigose with yellow simple hairs with granular ornamentation, faintly rugose when dry, revealing the underlying endocarp rugosities.
Mesocarp 100–200 µm thick when dry. Calyx persistent. Length 20–37 mm, width 10.0–17.7, thickness 4–8 mm.
ENDOCARP. Cream, elliptical in lateral view, lenticular in transverse section, length ca 25.5 mm, width ca 12.8 mm, thickness ca 6.9 mm. Channel surrounding the endocarp in the plane of symmetry. Apex asymmetrical, acute in lateral view; base rounded, symmetrical. Outer surface of the endocarp rugose with ca 73–91 mounds; mounds more or less square polygonal, each with more or less branched freely ending channel inside. Mounds organized in 5–6 longitudinal lines separated by four main longitudinal channels. The main channel on each face reaching a pore positioned subapically. Vasculature of the endocarp in the channels between mounds; primary vascular bundle half-embedded, positioned in the channel surrounding the endocarp. Endocarp wall 293–329 µm thick excluding mounds (484–496 µm thick including mounds). Endocarp wall with three cell layers: outermost layer with 1–4 rows of isodiametric, occasionally anticlinally oriented cells, cells 26–35 µm in length, followed by a layer with 7–10 rows of periclinally oriented cells, cells 24.6–29.0 µm in width; innermost layer with one row of periclinally oriented cells, cells 10.1–13.8 µm in width, lining the inner endocarp surface with regularly spaced and rounded papillae; papillae 21.9–30.6 µm (av. 25.6 µm) in diameter, ca 138 papillae per 0.25 mm 2. Locule lacunate.
