Description

FRUIT. Oblong, shriveled when dry, revealing the underlying reticulum of endocarp ridges. Mesocarp ca 200–250 µm thick when dry. Length 10–40 mm, width 8–15 mm, thickness 5–8 mm.

ENDOCARP. Brown, length ca 19.2 mm, width ca 7.7 mm, thickness ca 6 mm. Outer surface of the endocarp ridged, with 4–6 main ridges longitudinally, two of them reaching the point of the base on each face. Ridges rounded and thick, delimiting a reticulate pattern, faintly apparent, enclosing ca 40 small areoles with simple freely ending ridgelets. Endocarp wall 120–136 µm thick excluding ridges (163–185 µm thick including ridges). Endocarp primary vascular bundle outside the endocarp wall. Endocarp wall with three cell layers: outermost layer with 2–3 rows of isodiametric to periclinally oriented cells, cells 12.7–21.7 µm in width, followed by a layer of 6–7 rows of periclinally oriented cells, cells 8–19 µm in width. Innermost row contains small, periclinally oriented cells, cells ca 6.7 µm in width. Locule surface smooth.
