Description
FRUIT. Globose, symmetrical at the apex. Epicarp smooth or slightly rugose when dry, revealing the endocarp faint rugosities. Mesocarp ca 350 µm thick when dry. Calyx persistent. Length 18.8 mm, width 14.7 mm, thickness 10.4 mm.
ENDOCARP. Globose in lateral view, length ca 15.8 mm, width ca 13.6 mm, thickness ca 10.2 mm. Keel surrounding the endocarp in the plane of symmetry, with a central channel. Base with a small rounded protuberance at the point of the base. Outer surface of the endocarp smooth with sparse rugosities randomly distributed, and short ridge beginning the apex and running transversally and subapically over 0.5 mm at the most. Vasculature of the endocarp free. Endocarp wall 714–809 µm thick. Endocarp wall with two cell layers: outermost layer with ca 17 rows of anticlinally oriented cells, cells 21.7–32.8 µm in length; innermost layer with 14 rows of periclinally oriented cells, cells 16.9–26.7 µm in width. Inner endocarp surface smooth, not lacunate.
