Description

FRUIT. Elliptical, apex elongate. Epicarp strigose, with yellow simple hairs with granular ornamentation, shriveled when dry, faintly revealing the underlying endocarp ridges. Length 23–30 mm, width 13– 18 mm, thickness 7–10 mm.

ENDOCARP. Elliptical in lateral view, length ca 17 mm, width ca 12.2 mm, thickness ca 8.2 mm. Apex slightly asymmetrical, acute in lateral view, with apical hole. Outer surface of the endocarp pitted and ridged. Ridges sharp and thin, with three main longitudinal ridges; the median ridge running from the point of the base up to ¾ of the endocarp length, the two lateral ridges running from the point of the apex almost to the base, each connected with the keel by four transverse ridges enclosing three areoles. Pits large (0.4–1.2 mm in diameter), exclusively circular, organized in longitudinal lines, 8–9 pits longitudinally, ca 6 pits transversally with one pit between median ridge and lateral ridges, and two pits between lateral ridges and the keel (ca 44–48 pits per face). Pits associated with bullate tubercles, ca 302 µm in length inside the endocarp. Cellular details of endocarp wall unknown. Inner endocarp surface with regularly spaced and rounded papillae; papillae 13.2–18.0 µm (av. 15.9 µm) in diameter, ca 600–800 papillae per 0.25 mm 2. Locule lacunate.
