Description
FRUIT. Elliptical, brown when mature, length 25–34 mm, width 15–17 mm, thickness 11–13 mm.
ENDOCARP. Cream, with a cork-like texture, elliptical in lateral view, lenticular in transverse section, length ca 33.8 mm, width ca 17 mm, thickness ca 10.7 mm. Keel surrounding the endocarp in the plane of symmetry, with the thicker margin containing the primary vascular bundle embedded within the endocarp wall. Apex asymmetrical in lateral view; base rounded, symmetrical. Outer surface of the endocarp ridged with two types of ridges. Primary ridges comprising three main longitudinal ridges; the median ridge reaching the point of the base. Primary ridges large, rectangular, with a median channel and with wavelet ornamentation on both sides of the channel; delimiting a reticulate pattern enclosing 7–8 square-polygonal areoles transversally. Secondary ridges thin and sharp, delimiting a dense reticulum enclosing numerous areoles. Vasculature of the endocarp resting in the channels of the ridges. Endocarp possessing a symmetrical pair of pores positioned eccentrically and subapically on the endocarp faces. Endocarp wall 258–322 µm thick excluding ridges (433–597 µm thick including the secondary ridges and ca 959 µm thick including primary ridges). Endocarp wall with three cell layers: outermost layer with ca 2–4 rows of isodiametric to anticlinally oriented cells, cells 30.7–32.6 µm in width; middle layer with 11 rows of periclinally oriented cells, cells 11.9–21.0 µm in width; innermost layer with one row of periclinally oriented cells, cells 6.3–8.4 µm in width, covering the inner endocarp surface with papillae. Locule lacunate.
