Description

FRUIT. Slightly asymmetrical at the apex, brown-black when mature. Epicarp strigose, with yellow uncinate hairs, shriveled when dry. Mesocarp 200–250 µm thick when dry. Length 30–38 mm, width 15–23 mm, thickness 9.0– 13.4 mm.

ENDOCARP. Globose in transverse section, length 26.1–27.6 mm, width 12.9–14.0 mm, thickness 10.5– 10.8 mm. Keel surrounding the endocarp in the plane of symmetry. Apex acute. Primary vascular bundle positioned outside the endocarp wall. Endocarp wall 474–490 µm thick. Endocarp wall with three cell layers: outermost layer with ca 14 rows of anticlinally oriented cells, cells 20.3–40.5 µm in length, followed by a layer with ca 7 rows of periclinally oriented cells, cells 16.1–22.4 µm in width; innermost layer with one row of periclinally oriented cells, cells 6.7–8.7 µm in width, lining the locule surface with regularly spaced and rounded papillae; papillae 12.8–20.6 µm (av. 15.7 µm) in diameter, ca 1020–1070 papillae per 0.25 mm 2. Locule surface not lacunate.
