Description

FRUIT. Epicarp puberulent, reticulate-rugose when dry, revealing the underlying rugosities and ridges of the endocarp. Mesocarp thin. Length 14–21.4 mm, width 10.0– 11.1 mm, thickness 7.0– 11.2 mm.

ENDOCARP. Brown, globose in transverse section, length ca 19.4 mm, width ca 10.7 mm, thickness ca 10 mm. Sharp keel, sinuous and serrated, surrounding the endocarp in the plane of symmetry. Apex acute and asymmetrical; base rounded, slightly asymmetrical. Outer surface of the endocarp rugose and ridged. Ridges sharp and diffuse with only a median ridge serrated. Surface covered by ca 70 rugged protuberances, evenly distributed, and by ‘ridges’ that form small , vertically and longitudinally elongate mounds. Endocarp with a symmetrical pair of pores situated at the merging of the apex and the median ridge. Endocarp primary vascular bundle positioned outside the endocarp wall. Endocarp wall 370–477 µm thick excluding ridges (1200–1380 µm including ridges). Endocarp wall with three cell layers: outermost layer with 1–2 rows of isodiametric cells, cells ca 27–40 µm in diameter; followed by a layer of 15–21 rows of anticlinally oriented cells, cells ca 19–24 µm in length; innermost layer with 5–6 rows of periclinally oriented cells, cells ca 9–14 µm in width. Locule surface smooth and lacunate.
