Description
FRUIT. Elliptical, red when mature. Epicarp glabrous, ridged, with diffuse long arbuscles, revealing the underlying reticulum of endocarp ridges. Mesocarp 200–250 µm thick. Length 24–26 mm, width 18.3 mm, thickness 14.0– 17.5 mm.
ENDOCARP. Elliptical in lateral view, globose in transverse section, length ca 23 mm, width ca 17.6 mm, thickness ca 17 mm. Keel faintly apparent, with a median channel, surrounding the endocarp in the plane of symmetry. Apex truncate; base rounded and slightly asymmetrical, positioned in opposition to the apex asymmetry. Outer surface of the endocarp ridged with 3–4 main longitudinal ridges; the median and a lateral ridge reaching the point of the base. Ridges sharp and thin, with a median channel (corresponding to the trace left by the vasculature of the fruit), forming a partial and sparse reticulum with ca 16–17 areoles, some areoles transversally extended, others small and randomly positioned, with freely ending ridgelets, occasionally arbusclular. Endocarp possessing a symmetrical pair of pores positioned eccentrically and subapically at the apical end of the median ridge. Vasculature of the endocarp resting in the channels of the ridges; endocarp primary vascular bundle positioned outside the endocarp wall. Endocarp wall 240–362 µm thick excluding ridges (400–430 µm including ridges). Endocarp wall with two layers: outermost layer with 3–4 rows of isodiametric cells, cells 18–28 µm in diameter, innermost layer with 10–13 rows of periclinally oriented cells, cells 13–21 µm in width. Locule surface smooth and lacunate.
