Description

FRUIT. Elliptical, red when mature. Epicarp pilose and puberulent, with long and thin red hairs and simple hairs with granular ornamentation, shriveled when dry, revealing the underlying endocarp rugosities. Mesocarp ca 14 mm thick. Calyx not persistent. Length 53–95 mm, width 40–58 mm.

ENDOCARP. Cream, elliptical in lateral view, globose in transverse section, length ca 58 mm, width ca 37 mm. Keel surrounding the endocarp in the plane of symmetry, with the thicker margin containing a vascular bundle embedded within the endocarp wall. Apex slightly asymmetrical in the lateral view; base rounded, symmetrical. Outer surface of the endocarp rugose, with large mounds in 3–4 major longitudinal rows. Mounds formed by folds of the wall. Endocarp wall 694–850 µm thick without and with ridges. Endocarp wall with two cell layers: outermost layer with 15 rows of isodiametric cells, cells 20.5–58.5 µm in diameter; innermost layer with 15 rows of periclinally oriented cells, cells 10.3– 32.0 µm in width. Inner endocarp smooth with long and thin hairs. Locule surface folded, not lacunate.
