Jongkind & O.Lachenaud Fig. 9.1–9.9 Material examined Specimen used for endocarp and fruit description CAMEROON • 1969; J.J. Bos 4277 ; P[ MNHN-P-P04495129 ]. Description FRUIT. Epicarp strigose, smooth when dry. Mesocarp 750–820 µm thick when dry. Length 21–25 mm , width 9–15 mm , thickness 5.0– 10.2 mm . ENDOCARP. Cream, lenticular in transverse section, length ca 18.4 mm , width ca 9.2 mm , thickness ca 8.5 mm . Keel surrounding the endocarp in the plane of symmetry. Apex slightly asymmetrical, bulged; base subacute, symmetrical. Outer surface of the endocarp ridged, with 4–6 main longitudinal ridges; the median and a lateral ridge reaching the point of the base on each face. Ridges angular and broad, almost rectangular, with a median channel clearly visible, delimiting a reticulate pattern enclosing 20– 24 polygonal longitudinally elongate areoles. The ridges merge with the bulge at the apex. Endocarp primary vascular bundle in a channel on the keel. Endocarp wall 180–200 µm thick excluding ridges ( 320–385 µm thick including ridges). Endocarp wall with ca 17 rows of periclinally oriented cells, cells 7–16 µm in width. Locule surface smooth and lacunate.
