Description

FRUIT. Ovoid to elliptical, with the apex occasionally acuminate, laterally compressed, red when mature. Epicarp strigose to puberulent with yellow simple hairs with granular ornamentation and uncinate hairs, more or less ridged when dry, revealing the underlying reticulum of endocarp ridges. Calyx persistent,separated from the fruit by a gynophore.

ENDOCARP. Brown, elliptical to ovoid or partially globose in lateral view, lenticular in transverse section. Keel surrounding the endocarp in the plane of symmetry. Apex slightly asymmetrical in lateral view, with a subapical pore on each face, occasionally absent; base symmetrical. Outer surface of the endocarp pitted and ridged or rugose. Pits large, exclusively circular, organized in longitudinal lines. Pits associated with small, bullate tubercles protruding into the locule. Ridges thin to thick, forming a reticulate pattern, delimiting a few polygonal areoles. Vasculature of the endocarp resting on the ridges. Endocarp primary vascular bundle outside the endocarp wall. Endocarp wall with at least one layer with rows of periclinally oriented cells. Locule surface with regularly spaced and rounded papillae, occasionally lacunate, often hardly discernible.
