Description

FRUIT. Elliptical, slightly asymmetrical at the apex, laterally highly compressed, red-brown when mature. Epicarp glabrous. Calyx persistent.

ENDOCARP. Cream, elliptical in lateral view, lenticular in transverse section. Small keel surrounding the endocarp in the plane of symmetry. Apex slightly asymmetrical in lateral view; base rounded and symmetrical.Outer surface of the endocarp ridged, with thin rounded to sharp ridges delimiting a reticulate pattern enclosing areoles; most areoles with freely ending ridgelets. Vasculature of the endocarp free or resting on the ridges; endocarp primary vascular bundle positioned outside the endocarp wall. Endocarp wall thin, divided into distinctive layers, at least one layer with anticlinally oriented cells (outer part) and another with periclinally oriented cells (inner part). Locule surface with regularly spaced and large papillae, irregular in shape. Locule surface lacunate.
